Hi Jez,

happy to stop talk-gb-thenorth and merge it but how would I do that? it
would be nice if it was kept in archived form

This one has not been used for several years now - it has 60+ subscribers.

Re: [Talk-GB] Possible Unattributed Map on Labrokes Website

[Tim Waters]

I think it's Blipstar  - a UK company who provide store locator tools

Looking at their example map
https://blipstar.com/blipstarplus/examples it seems to be the default
to hide the attribution (via CSS media query) on narrower window

Re: [Talk-GB] When is a hedge a wood?

[Tim Waters]

At first look I thought this was a once-hedge, a hedge that's been left to
itself. But each tree is equally spaced, looks the same age, doesn't seem
pollarded or coppiced as what you might expect a tree in a hedge to be, and
so I don't think that's the case now.  So to my mind now, it's a fence,
with individual mappable trees.

A hedge implies a barrier of kinds.

Re: [Talk-GB] Mapping horse steps?

[Tim Waters]

Wikipedia calls them "mounting blocks"
https://en.wikipedia.org/wiki/Mounting_block

I spotted a new ish concrete one the other day which had an official
looking "horse riders may mount here" sign above it, but I don't think
those signs are in the HM Sign Manual.  I prefer "mount" to "dismount" and
it might reflect the intended purpose of it, it's easier to fall off than
climb on the beasts!

Going back to the wikipedia page, these block steps are not only horse
specific, but could have been used to get into carts and buggies, too.

Re: [OSM-talk] Directed Editing Policy

[Tim Waters]

I've a couple of examples, and a couple of questions which might aid the
discussion.

I recently did some work which would label me as both a directee and a
director. For each changeset I added a custom changeset tag which I thought
was the sensible thing to do. It was also helpful for me to be able to
track the work I did, amongst my other edits at that time. I'm assuming
that this bundle of changesets could be searched for an clustered, and that
I wouldn't need to create another changeset tag for a similar tranche of
work in the future. At the time I did actually briefly consider writing a
wiki page about the work, but thought that too onerous (it was a short
project) and against the spirit of OSM (the world should be free to edit
the free map). I thought I shouldn't have to document all my actions to
contribute. If the policy was adopted, I'd have to go along with it. I
would feel less of an equal, or more under scrutiny if I did.

Some time last year I ran a mapping workshop where participants were
mapping a specific type of feature, using custom presets using established
tags. The use of the presets helped ensure that the tags were consistent.
We didn't really use any specific changeset comments or any new tags, but
when Field Papers was used, I believe this was recorded. The custom editor
was able to add changeset tags too. Again the tools help record the custom
sources involved. Before I ran the workshop, although it was free, public
and publicised, and although the project itself was documented on the wiki
and elsewhere, I did not feel any need to document the actual directed
mapping.

These are just my two experiences, the policy as a whole reads well and I
understand that there is an issue which needs addressing, I hope our
discussions can bring some nuance and improve matters.

Now - the questions:
When I was reading the draft policy, I imagined the state of the Wiki.
Would it be polluted full of stale pages of small directed mapping projects
after a few years?
As the suggestion is that a timeframe is added to the page - is this easily
machine readable and parseable within the Wiki software?
Would it be easy to just see currently active projects, or just see those
projects which were upcoming?

Re: [Talk-br] [OHM] Possibility to build a new Historic Project to OSM

[Tim Waters]

Hi Rodrigo,

Speaking of OpenHistoricalMap I think historic events bound to
geography would be welcome. The Historic Event proposal was for the
different but of course bigger OSM project.The example given in the
wiki page was historic battlefields which would be suitable.

I think there could be discussion about notability. For example, if a
city records and notifies that an event occured in a place (e.g. Blue
Plaques) then we can say it's notable for sure. At any rate the event
should be able to be verified by another mapper.

I don't think that more general events such as "crimes in 1930s" would
be appropriate in OHM however - at one geographical level this is
statistical information, and one that might be better linked to the
historic geographic area. At individual level it may not be notable -
but a prominent assasination might be.

So I think OHM could fit some of your needs. Getting the historic
geodata and basemap in could be more of a challenge!

regards,

Tim

At time of writing this email, the Kickstarter project has reached its

[OSM-talk] The New Cloud Atlas - Mapping Physical Infrastructure of the Internet with OSM

[Tim Waters]

Hi folks,

with Ben Dalton, I'm happy to properly launch The New Cloud Atlas
project at http://newcloudatlas.org

I've written a blog post to explain it in more detail:
https://thinkwhere.wordpress.com/2016/08/17/the-new-cloud-atlas-mapping-the-physical-infrastructure-of-the-internet/

It's a project to collect and make a map to better understand what
"The Internet" means, physically and geographically. The site has a
tweaked iD editor with custom telecoms presets, it creates a couple of
map tilesets showing these features from OSM, with clickable features
on the map.

We encourage you to map your local data centres, street cabinets,
telephone exchanges, telephone poles, manhole covers and more!

Telecoms features in OSM are not consistently mapped with regards to
each other which could provide an opportunity for some consolidation
or making new taxonomies. I've created WikiProject Telecoms to help
with this tagging discussion:
https://wiki.openstreetmap.org/wiki/WikiProject_Telecoms

Cheers and I look forward to your comments!

Re: [OSM-talk] Uber most likely using OSM data

[Tim Waters]

Hello,

given they may well have a very large body of GPS traces, they may be
using these to route along.

The way to check if they are using OSM is if the OSM map has
intentional errors - a kink in the road where there is none on aerial
imagery or on our GPS traces, for example.  Some of my early edits
were done just by phone and a bluetooth GPS mouse - in the days before
aerial imagery, and some of the roads had a few bends which were not
there in reality, and this assisted me in identifying some of the
previous users of our database.

Another way is perhaps by comparing the resolution of the data, a bit
like in the examples, showing where the bends meet up - comparing a
road with lots of bends, nodes in a short distance. Seeing if the
vertices match up.

Cheers,

Tim.

Re: [OSM-talk] What pointing device you use for mapping?

[Tim Waters]

I use a trusty Microsoft Intellimouse (although I do not customise the
buttons), but I'm really replying to an observation about a helpful
tip for mapping parties and workshops.

When putting on a mapping party / workshop where people bring their
own laptops, bring a bag of mice for participants to use! The Missing
Maps  / OSM London do this and it seems as if all of them get used.

(I also find it funny, how, several years ago at mapping parties we
used to pass around a bag of GPS units to map, now it's a bag of
mice!)

Back on topic, I'd be curious to hear if the assorted map teams in
companies like Mapbox etc use any specific hardware to point and map
and increase productivity...

Cheers,

Tim

Re: [OSM-talk] What3words

[Tim Waters]

Heather and folks who are often perplexed,

are you actually perplexed or do you understand but disagree? I ask
because I have heard some mappers say the opposite: "I don't
understand why people would choose w3w!!11". Is it a turn of phrase?
Or a genuine plea for illumination? I often disagree with blind
vitriol, but I try to understand why it exists. The words we say often
give different responses. For example in the UK many people said "I
don't understand why people voted for Brexit" and some of them
genuinely did not know of any reasons why people voted that way
(filter bubble doesnt help), whilst others said that phrase, but could
understand why others voted that way but simply disagreed with the
reasons. Some people simply could not put themselves in the
oppositions shoes. The cognitive dissonance hurts too much.  I
therefore think its not just a turn of phrase for all. So here's a
response which I hope covers both angles:

In this example of w3w should the OSM community or the OSM Foundation
provide reasons why people disagree to help those who do not
understand community responses to product, or, should the OSM
Community or the OSM Foundation communicate better so that differences
of opinion are valued and can coexist with each other? Should reasons
on both sides be listed, or should we work so that blind vitriol and
anti vitriol statements be lowered? Is the problem the thing, or is it
that the thing cannot be easily understood?

Personally, I like w3w, I don't think the promise to release the code
if it goes belly up means anything. Contracts and terms of conditions
can be changed whenever, and it looks like they are aiming to be
acquired. Also, if they are successful it would never be released, so
why should we wait for it? They are VC funded, after all so they want
to grow and get a profit. I disagree mostly with the proprietary 3rd
party access. It's not open and not the OSM way. Its a proprietary
gatekeeper of information, something diametrically opposed to our
little mapping project. Would someone say the proceeding few sentences
was vitriolic? I don't think so. Critical yes. Was it offensive? Maybe
their investors don't like it, but I think it should be allowed to be
said, right?

However, I also disagree with criticism from mappers directed at
Mongolia which is patronising at best. To go with w3w is similar to
any proprietary software contract, which big businesses and big
countries do every day. It's not something I would promote generally,
it's not an open way forward is it? However it gives people jobs, and
its the money making capitalist world we live in. I believe w3w whilst
being a poor choice is a workable choice. And it may be a great choice
for the country if it works for them. If the country asked me, I would
not have recommended w3w, but dont hold it against them! Just like
using closed data, or proprietary software is a poor choice, it does
actually work. Microsoft or Esri products actually work pretty well!
(and so do their better FOSS alternatives of course). I do reserve my
vitriol to protect open data and open source, as this protects this
OSM community and foundation and what I think we stand for. Mongolia,
I believe made a good choice in their eyes for their country.

I hope this helps the perplexity, if there is genuine perplexity. Many
people do not understand the issues, and that's okay, and I want to
help people understand things if they are open to learn. And i hope
this helps understand some of the issues why people disagree with the
project if there is a genuine need to learn about some of these. I
want to help people empathise with others, to put themselves in their
opponents shoes and see that they are not actually opponents after
all!. I suspect the reality in many people's cases with controversial
subjects it is a mixture :)

best regards,

Tim

Re: [Talk-GB] Night Time Aerial Imagery?!?

[Tim Waters]

This is great! Thanks for putting these online.

I've been trying to find the source on the EA website - as I was
wondering whether they were also recording other bands (infra red etc)
which could, I imagine, be used to map vegetation.

Also, I was curious to find out why they chose these specific towns
and cities, and not others - or in other words, why they captured
these images in the first place.

Also - for initial directors, to remind folks, these are just in name
only for a little while before the elections when they all resign and
new ones are elected?

Are the some hospitals that do not have pharmacies?  Would these be
the smaller clinics, or would they be tagged differently anyhow?

Re: [OSM-talk] Upload slowness - what's going on?

[Tim Waters]

I believe the Dev mailing list may have some of your technical answers
https://lists.openstreetmap.org/pipermail/dev/2016-May/thread.html

It appears from that list that the database servers are now a few
hundreds of miles from where the web servers are, causing the increase
in latency. I do not know if this is a permanent change, the thread on
osm-dev does seem to indicate that things are still in flux.

Re: [Talk-GB] OSGR & OSM

[Tim Waters]

There are a few tools out there which may do the job, I seem to recall
a few. http://nearby.org.uk/ might have it.

The search keywords which might help is "os national grid spherical
mercator". Do remember that a tile is not the same square as an os
grid square, but you should be possible to click on a point and get
that point in whatever coordinate system you need.

Re: [Talk-GB] [UK Chapter] Definition of OSM.

[Tim Waters]

Frederik is correct in saying that OpenStreetMap Project does not
appear in the OSMF Articles of Association.

However, on the OSMF website, the following words are used: "The
Foundation supports the OpenStreetMap Project."

So the wider OSM "thing" is the OpenStreetMap Project rather than the
OpenStreetMap Community. I quite like that differentiation, even
though I cannot find the definition of what the project is!

"supports" is also a quite different meaning than "managed by"

If we wanted to have a definition that includes the OSMF: "The
OpenStreetMap Project as currently supported by the OpenStreetMap
Foundation Ltd" perhaps?

Re: [Talk-GB] UK war office maps of Africa digitised

[Tim Waters]

Hi folks,

so after a fix was applied to the Wikimaps Warper the collection of
581 maps from Wikimedia Commons was re-imported and added to a mosaic
(layer)

https://commons.wikimedia.org/wiki/Category:War%20Office%20Archive%20%E2%80%93%20British%20East%20Africa

The mosaic:
http://warper.wmflabs.org/layers/4

The Tiles link is http://warper.wmflabs.org/layers/tile/4/{z}/{x}/{y}.png
and the WMS details can be found at
http://warper.wmflabs.org/layers/4#Export_tab

and of course individual maps have their own WMS and Tiles endpoints too

Cheers,

Tim

p.s. Note that loading up a map for the first might take a once only
period of a couple of minutes as the map gets requested from commons
and is loaded up in the warper ... you should see a progress bar in
that case!

p.p.s. There's an issue with the warper not getting the correct
thumbnail for some of the maps, but it shouldn't affect how it works
in the warper.

Great stuff. I think a few hundred maps (if not all) from this collection
are already in the wikimaps warper.
However there was an issue with making a mosaic (stitched layer) for the
category, so this will be fixed soon.

The "warped" parameter in the wiki page enables the button for users to get
from the wiki to the warper. You can add it to the pages, or you can search
for them within the warper itself.

I think the British Library also has control points for the maps which
could be added to the warper when ready (I'd have to double check on this
point though).

Tim

The minutes do not state that people agreed to set up non OSM mailing lists
as a replacement to the current system. I couldn’t find any discussion
about emails or mailing lists. All I could find was one action point:

"Rob: We should get e-mails. I’ll put a form on the talk-GB list."

Could you tell us who didn't attend the meeting and may be missing out on
some background, what is this form for?

For example, what were the attendees views on this mailing list talk-gb?
Why should people sign up on this new form, what benefits to signing, what
potential losses to not signing up etc. Is this new list private, non
public, or public and open to all? Is the intention to have it as members
only (similar to HOT-membership) or not?

Sorry if it may seem like you would be repeating yourselves from previous
discussions, but I feel it could be useful to get all potential interested
members on board :-)

Re: [OSM-talk] What3words

[Tim Waters]

As an infrequent poster to osm-talk I think I'm excluded from Colin's "3 or
4 people" and "most active participants" and am not in the Fetted Inner
Core (at least I wasn't the last time I checked!) - however my views are
similar to the ones previously, in this case, very sorry Colin! :-)

In short, What Three Words does initially appear to be a "wow that's cool"
techy project, but given closer inspection it's not that suitable for an
open data project. It is not open or ground verifiable *at the moment*. Yes
it has got recently millions in funding. I frankly would expect more public
pressure to get it used in OSM than there has been. Perhaps they are
avoiding direct pressure until their board demands it, or perhaps they are
approaching the Foundation obliquely. I do know that they have been doing a
lot of work promoting the service to development and humanitarian
organisations, and they really are good at promoting their product. Very
many good quality proprietary data and software for profit companies make
healthy profits from working in the development and humanitarian
industries. One could think that such good causes should be the preserve of
Libre Software and non profit organizations, but that's a fallacy. Anyhow
I'm digressing, sorry!

So, if my local shops start to use it in the future, if "people on the
ground" use it, then I would say it could be added then - but there's no
benefit to mappers, or people on the ground for adding it before that stage.
At that stage, before people actually use it, it's just another way of
encoding location, and therefore redundant. Futhermore in both cases, the
only way for another mapper to tell if the reference is correct is to use
the third party API.

Given their approach and closedness however, I very much doubt that most
people will start using it. Perhaps they will buy into getting a developing
country to use it nationally, but we will have to see what happens. So, in
the future, if normal folks use it on the ground, it may be useful to add
it, in my humble opinion. Perhaps they will open source their algorithm but
keep their APIs and services closed, again we will have to see. Perhaps *if
and when it is used by people on the ground* we can pressure the company to
open up enough of their solution to make it OSM friendly and for them to
still please their board of investors?

But the main reason I don't see it being used in OSM is that it goes
against the spirit of the project.
This spirit of openness, collaborativeness and Libre software. It's closed,
it doesn't look like it will ever be open and it ties the usage of the
system through a closed API.  It's a closed data project, and OSM is *the*
open data project.

Tim

Ahh correction, there *is* data at 25cm and 50cm in some areas (where

Re: [OSM-talk] Abandoned Rails

I'd like to recommend OpenHistoricalMap.org (OHM) which will welcome
all types of historical, disused and abandoned features. Please, go
add every abandoned railway to OHM, and then together we can
eventually get an accurate map of 1880s railway network compared to a
1940's, compared to yesterdays world!

 Hi

 I'd therefor like to propose that abandoned railways be treated like

 doing
 the opposite.

 I 100% agree. The amount of data required to map abandoned railroads
 is tiny. An occasional way through a new development is not going to
 hurt anybody or impair normal mapping activity.

 Apparently, the people that like to map railroads think OSM is the
 best place to do this. We are not in any position to be chasing them
 off. OSM has a long, long way to go still. Above all else, it needs to
 more active mappers if we are serious about being the best map for the
 entire world. Also, It seems likely they are also mapping non
 controversial things like roads while working on the railroads.

 Dave F, OSM is doing just fine. It is full of contradictions,
 redundancies, disagreements, and broken rules (see the tagging list).
 It is not some kind of business database that requires normalization,
 strict schema definitions, and vigilant protection. It can't have any
 once sentence rules defining its boundaries. It is a great big blank
 sheet of paper, relax and let the railroad people draw on it a bit.
 Nobody is going to get hurt.

 calculate the date?

 It would be nice to know this date early.

 Best regards

Re: [Talk-GB] Fwd: Underground services

[Tim Waters]

I'm also interested in underground cables and mapping communications
routes, in particular the major internet trunk cables.

My question would be, similar to tunnels and other somewhat hidden
underground features -  how would we represent lengths along the route
where the positioning is unclear.
Before better sources of positions become available, would straight lines
in the database from A to B be allowed, or desired?
Shouldn't these unclear, holding lines never be rendered?

And, more interesting: how can we get better positioning information?
Could the scars along roads be used to help interpolation of positions?
Could we develop hand held instruments to detect various things?
Does dowsing work?
Can we use the markings sprayed on the pavement by utility companies to
identify what's there?

Cheers,

Re: [Talk-GB] Update: Deploying our own version of NYPL Building Inspector

[Tim Waters]

Hi folks,

here's my thoughts

Moving forward:
Remember that people will fix the automatic vectorisations if they are off
- they can also add extra buildings if need be also.
I think we have enough to move it forward and see what happens. As the NYPL
Building Inspector says: Don't let perfect be the enemy of good

Branding:
Yes I think it should be branded an OHM project - but with space for donors
and supporters particularly if other organisations apart from NLS want to
get involved.
I've also forked the project into the OpenHistoricalMap repo
https://github.com/OpenHistoricalMap/building-inspector as I think that's
the best place for it (not sure why I didn't do that at first, tbh)

cheers,

Tim

 Hi All,

 An update on progress deploying our own version of NYPL's historic map
 vectorizer/building inspector tool [1].


1. Chris Fleet from National Library of Scotland (NLS) has kindly
provided a couple of GeoTiff example scans from their London 1890's maps
[2].
2. Using the NYPL map-vectorizer [3] I am able to get initial building
outlines from these maps.
3. Tim Waters has managed to get a copy of the NYPL website up ready
for loading NLS's maps/vectorized buildings. This is at [4]. Meanwhile he
has opened initial conversations with the British Library who also have a
good collection of historic maps.
4. I am concerned that the initial building outlines end up leaving
gaps between terraced buildings. This is due to the way that the NYPL
map-vecotrizer works to trace the _inside_ of buildings. I'm no GIS expert
so may be missing a simple solution. However I have noticed that we could
use the Strava Slide tool [5] to 'slide' the building polygons onto the
building walls. In essence this works by using pixel blackness of the map
scan (rather than GPS traces as per the initial Strava Slide tool).
5. I have contacted Paul at Strava to ask about this. He thinks the
idea is a really good one and is hoping to add the functionality we will
require. He's a bit busy at the moment but is presenting at FOSS4G (in
September?) and would like to use this as an example of what's possible
with slide.

 So, where does this leave us? Well we're at the same place as NYPL so
 could go ahead with adapting the website Tim put up to our needs and then
 launch when ready. Or, we could hold off until Paul at Strava is able to
 add the functionality we need to the Slide tool.

 Thoughts?

 Also, are folks happy for this to be branded as an OpenHistoricalMap
 project? (Chris at NLS is okay with this).

 Rob

Re: [Talk-GB] [OHM] New York Public Library - Building Inspector

Hi folks,

I've heard back from the British Library - they are hugely interested with
the Map-Vectorizer work - it's really encouraging.

In brief they said that they were positive but that they'd need to get some
things sorted first, looking at licensing, formats etc and they would
update me soonish.

In the meantime I suggest we go ahead with the NLS maps and see if we can
get our stack up and running with those maps?

 Chris Fleet (from NLS) has sent me some test maps, however these are Jpeg

Those are some good examples - they appear to be around the same scale
also.
They are monochrome and don't have addresses which should limit a couple of
the types of the tasks.  Could be worth trying the Building Inspector with
this dataset.

I wonder if there's anyone from the NLS on list?

 There is also some great London data:

  Was that a serious suggestion?


yes, but I can see how it could look flippant. Sorry!

Basically there are not many open data sources of house addresses. From
what I hazily remember the courts already publicly publish on paper for
anyone to view the names and addresses of people involved. I gathered that
they include the addresses because there may be more than one John Smith
going to trial at any one time. They may also do this for weddings..

I could be wrong, and my memory is fuzzy - hence the email wondering if
they would publish them. If anyone knows, please enlighten us!

I think it's likely that postcodes are excluded, but you never know. It's
also likely that this information even if published on paper may not be on
an API - makes sense, but again who knows!

If there is a source of addresses, it is useful:
* Mappers can use it to check to see if the street exists and has been
mapped
* Mappers keen on adding in addresses to streets can use it (or a bot) to
validify that there is that number on the specified street.
* FreeThePostcode or other open postcode database etc could be added to.
The postcode and address exists, it can be contributed to. Assuming the
licenses are compatible.

Re: [Talk-GB] NPE data

[Tim Waters]

I think this shows one of the benefits of adding source tags to our edits
 - because in the future a better source may come along.

At the time a lot of natural features in the UK were traced from NPE maps
and they made many parts of the UK in OSM much better than nothing.

It's really encouraging, and we should further encourage folks to re-map
and edit areas.  When I encounter something tagged with NPE as the source,
I feel more confident moving and editing it whether aligning a stream to
Bing imagery or to my GPS trace we'd also need to remind people to
change the source tag as well!

Cheers and happy mapping!

  I tend to see an NPE tag as something that needs attention. A lot of

  NPE maps. That includes a lot of roads, I am getting through
  resurveying them but even today I found one that according to my GPS
  was 50m from where it should be.
 
  In the case of a road I see it as an indication that there is a road

   I have come across some data tagged as source=npe. I know what the
  NPE
   maps are but my question is a bit of a newbies one... why is NPE data
   mapped on OSM if it is so old?
  
  
   I have just mapped an area for a customer of mine and there is a
   stream mapped running right through the centre of his property. It is
   tagged source=npe. The stream is no longer there and hasn't been for
   the 20 or so years he has owned the property.
  
  
   The old stream is showing up on OSM rendered tiles. His properly is a
   caravan site and so it would be good if his property did not have a
   stream that no longer exists running through it as it suggests that
  it
   might flood... which it doesn't.
  
  
   What is the situation regarding npe data? Can it be removed?
  Obviously
   I would just remove it!!! But is there is a process to get it
  removed?
   If it is to be kept, then how can we get the OSM tiles rendered
   without it showing this old stream? I can see that some specialist
   tiles might want to show old data like this but I wouldn't have
   thought it appropriate that normal OSM tiles would need to show this
   old data would it?
  
  
   Any help would be appreciated.

Re: [Talk-GB] Hand-drawn OS maps on Wikimedia Commons

[Tim Waters]

Hi folks,

just to add a little bit of brain food. I'm involved with the
georeferencing  / georectification side of things with the Wikimaps project
with Wikimedia Commons with Susanna Anas as mentioned earlier. We're using
a stripped down version of the open source mapwarper software which
essentially uses the GDAL library behind the scenes.

The idea is that an image of a map from the Commons can be georeferenced or
georeferenced into a new warped image.

There is of course a discussion about what to do with these resulting
images, but there's also some interesting design threads about how to embed
the georeferencing data back into the original image's metadata. This is
all with a view towards the metadata needs to a library or archive for
example (since they would be the types of organisations giving the source
images to Commons).

At the easiest level - what can be stored is a set of coordinate points,
ground control points which match features on image space to geographic
space. In addition a choice of mathematical transformation could also be
stored. The idea is that a user can replicate the processing using GDAL
and/or other desktop GIS programs. I'd say that corner points is useful for
placing the image roughly in space but it's not reproducible nor
comprehensive.

I would imagine that there's already some well established standards within
the library space. I think that any solution needs to be as open,
accessible and reproducible as possible.

It's only just getting it's feet off the ground but it's an interesting
discussion anyhow, please do join!

cheers and happy mapping!

 The answer is it isn't really done ;-)

 As far as I can tell Commons currently has no documented way of
 embedding anything other than a single coordinate pair for an image,
 which is obviously okay for photos but pretty unhelpful for maps (or
 indeed aerial/satellite imagery). This is a pity, as there's some
 nicely curated map collections there and of course Susanna's work is
 likely to bring us a lot more. (I'll drop her a note about this
 discussion)

 I put together OSDcoords, which Andy pointed out, as a quick and dirty
 hack to make them display with the hope that it could be transformed
 into machine-readable multi-point metadata at a later date; to the
 best of my knowledge, its the only example we have of this.

 Making something more usable out of it is probably beyond my
 cartographic expertise, but we're happy to take guidance!

The chart illustrates the alignment of buildings in the OSM database,

 I fear it will break completely the next time so was looking for a new

It works nicely for me. It appears to remember the setting for show

standard AA batteries, which are widely available. I'm not sure about
accuracy, but it improved when I turned it on to use the GLOSNASS.
Before that, it was a bit inaccurate when I carried it in my pocket.

 Hi Sebastian,

 It certainly sounds like your USB Controller is dead, but here's a thought:
 Garmins can be finicky about the cables they're used with. Are you using the
 USB cable that came with the Etrex 20? If not then it might not recognize
 the device when plugged in.

The supplied cable is a small one, about 1ft long, if that helps.
Otherwise, I would also recommend accessing the SD card directly.
I experienced some issues with the SD card, in that the fitting /
cradle for it was a bit loose and often became open when I changed the
batteries, which lead to the SD card not working - however, this
shouldnt affect the USB.

Re: [OSM-legal-talk] Digitizing from Balloon Maps

[Tim Waters]

From what I recall, but this is not canon (insert disqualification etc) Ed
Parsons from Google has basically said in one of his personal blog posts in
2008 [1] that interpreting the location of a point to create a new bit of
data using their aerial imagery does not make it derived data, because the
person uses their own judgement. This is contrasted to using say, the
corner of a building in google maps to do the same thing.  But legally, I
think it is still completely uncertain. In a couple of projects, with the
mapwarper (doing similar things), most institutions do not use the Google
supplied Aerial imagery, but a couple do.

I believe the example given was the mapping of recycling centres based on
the interpretation of the imagery. He used the words Skill and judgement.

I think, however, that this doesn't really allow OSM to trace wholesale the
google imagery - but for cases where a persons skill and judgement are
called, I think that it should be okay.

Re: [OSM-talk] Released: OpenMaps for iOS v4.0. An idea how to increase OSM awareness.

[Tim Waters]

Cool idea - I can see how it can help the OSM project.

There are a couple of things.

1) What to do about users adding the same point, but differently. For
example user A goes I'm at McDonalds, it's a cafe, user B goes I'm
at Mac Donalds, it's a fast food restaurant for the same location.
What one or two of the most popular chicken apps do is show these
points one after the other. What the OSM database could see is that
there's multiple points for the same thing.

2) The popular chicken apps are games. This is why they are popular.
You gotta add in game mechanics for it to work, coupons, badges and
other fun stuff. Without the gameplay, it becomes much like existing
services like http://mapme.at - personal location story applications.

I think the idea is great and potentially disruptive, but would need
to be promoted to the mass market, not just loveable geo freetards :)

 Today we released OpenMaps version 4.0 in Apple's App Store. It is a free
 map app based on OpenStreetMap and we believe it is the best. It is as slick
 as the built-in (Google) Maps application and if you ever used Maps on an
 iPhone you know that it's not a little thing to say.
 But this is not the reason why I am writing this email.
 I believe in OpenStreetMap. I really do. I want it to be the de facto map
 that everyone uses and I think most of you feel the same way. I also believe
 that OpenStreetMap is not getting the deserved user attention that we want
 it to receive. I think I have a solution how we could expose it to more
 users with OpenMaps for iOS.
 How? Just launch OpenMaps, find your favorite bar/pub/restaurant/etc. on the
 map, tap on it (yes, in contrast with Maps you can tap on POI icons in
 OpenMaps without needing to search for them; innovative, isn't it?) and send
 out a checkin tweet. A typical tweet will look like this:
 http://twitter.com/#!/zssz/statuses/7396822796476416
 Isn't Foursquare, Gowalla and now Facebook doing something similar you ask?
 Exactly. And look how popular they are. I believe that tweeting (checking
 in, commenting, etc.) about OSM POIs is a great way to increase OSM
 awareness. And it is a great way to share places with friends as when users
 tap on an openmaps:// link they will be shown the respective OSM element in
 OpenMaps (if they have the app installed on their device). They can even
 follow the recent Twitter conversation about an OSM element within the app.
 So if they want to share with the public that they serve amazing coffee at
 openmaps://n/957085286 then they can do that easily.
 I am enthusiastic about this and encourage you to adopt this because I
 really think it is a great idea to increase OSM awareness. Maybe it will
 catch on, maybe not. It all depends on the critical mass.

[Tim Waters]

Hi,

Zsombor, thanks for the reply, and clarifying about chickens.

When/how does OSM get edited with the app by the user? (Sorry, not got
an Iphone so cannot see for myself :)

Earlier in the thread you said
Every user that makes an edit to OSM via the app does it with their
own OSM user.

Cheers,

Tim

 Tim:

 1) Let me clarify. When users send out a checkin, comment, share tweet
 about an _existing_ OSM place that tweet goes to Twitter.

Re: [OSM-talk] Historical Data in OSM database

[Tim Waters]

We (EntropyFree) made a tentative start towards this a year or two ago at
OpenHistoricalMap.org - but although the resources needed for it didn't come
through, there was an incredible amount of interest in it. Essentially it
was planned to be a customised SM server instance with some backend
additions to accommodate changes of objects over time.

Another issue that was brought up was rendering of the maps - how do we
render historical data? By year range? By decade? How about if you wanted to
make a Georgian Map?  Do you use contemporary data where old data doesn't
exist? Maybe rendering to static tiles is the wrong approach?

Laurence gave the example of Crystal Palace, which moved position. But what
about a) buildings which do not change geometry, but change attributes,
name, use or ownership several times (Offices - bank - wine bar -
nighclub) and b) Buildings which change shape over time, whilst retaining
the same attributes (Church - church with tower - church with spire).

[Talk-GB] Volunteers wanted to lead mapping party with MapAction, Swindon, Nov 20/21

[Tim Waters]

Sent on behalf of the HOT and Mikel, we're looking for 2 people to go - this
should be a great day, and useful for both us and them :)


Hi

Are you interested to lead an OSM mapping party with MapAction on November
20/21, at their weekend training near Swindon?

MapAction is UK NGO that deploys GIS specialists in the crucial first days
after a disaster strikes. They were probably the first mapping crew on the
ground following the Haiti earthquake, and used OSM in their map production,
as well as communicating their needs back to us. They also helped arrange
the first Humanitarian OpenStreetMap Team deploy to Haiti in March. We've
been discussing how we can prepare better together for future disasters,
including setting up activation protocols within HOT, integrating technical
systems, and building up capacity within MapAction to contribute and use OSM
directly.

The training itself would basically be a mapping party, but with some
incorporation of materials developed by HOT in the Haiti trainings all this
year. The training exercise will be focused on mapping strategy in the
field. Teams will be given; a scenario, some data and various map request.
They will then have to decide what the mapping priorities should be for the
optimum humanitarian outcome.

This training is the first step. They're a great crew, and I'm sure it would
be a good time! It could just be Saturday, or you'd be welcome to camp over
til Sunday.

If you're interested, email me directly at mikel_ma...@yahoo.com.

Best

Re: [OSM-talk] Post-SOTM idea: Volcanoes of Olot

[Tim Waters]

I am also thinking of staying a couple of days after SOTM, was
thinking about Barcelona mainly, but Orlot looks looks interesting
too.

However, I see the words, volcanic landscape and bike rental and
match these with Spain in July and think that I'd rather be on a bus
than cycling up a volcano for half a day in reasonably warm weather :)

Cycling down the mountain is another matter!

Are there any nearby seaside resort towns that need mapping?

[Talk-GB] Settle OSM Mapping Party 15 May

[Tim Waters]

Hi,

apologies for cross posting, but OpenStreetMap and the Association for
Geographic Information's Northern Group are having a Mapping Party /
Field Workshop on Saturday 15th May in Settle, North Yorkshire and you
are all invited!

More details: http://wiki.openstreetmap.org/wiki/Settle_Mapping_Party

The town is reasonably well covered already, due to some previous
mapping activity and recent tracing from Ordnance Survey's Open Data
products, so the day should be a bit different than just collecting
the basic road backbone. GPS units will be available to borrow,
there's some great walking and cycling nearby and it's a lovely
picturesque easy-to-get-to town!

 Hi There,
 It will soon be time for OpenStreetMap to apply to join the 2010 Google
 Summer of Code Programme.   This gives students the opportunity to work on
 open source projects during the summer, for which they receive some payment
 by Google.   It costs us nothing more than providing a Mentor to guide the
 student.

 It would be really useful if we could put together a list of potential
 student projects to get potential applicants thinking.   The projects need
 to be fairly well defined to make it easy to judge 'success', so it is good
 to have specific targets.

 From recent discussions on these lists I have identified the following
 possibilities so far:

 Develop a stand alone 'Newbie'/'Introductory'/'Lite' Editor - the priority
 is ease of use rather than functionality.
 Help with the development of Potlatch 2 (maybe to include the 'lite' editor
 functionality) - we would need to help the applicants identify specific
 targets.
 Develop a simple 'mapping tool' for mobile phones to easily collect GPX
 traces, geotagged images and geotagged audio clips.  Ideally it should be
 capable of running on both Android, J2ME and Iphones, so you can have the
 same simple application no matter what sort of phone you use.
 Improve the usability of a simple mobile phone map editing application (such
 as vespucci for android).
 Incorporation of OSM data and traffic data.

 I am sure there are other things that I am not familiar with too - would it
 be useful for someone to do some work on tools to process OSM data in some
 way, or are there any tasks on the OSM server itself that could be turned
 into projects?

 Please will you give some thought to other possibilities and either add them
 to the GSoC 2010 Wiki Page
 (http://wiki.openstreetmap.org/wiki/Google_Summer_of_Code/2010) or reply by
 email if you prefer.

 and the other the entire island of Hispanolia

 I think these illustrate the rapid worldwide mobilization of volunteer

 The videos are based on the timestamps in GeoFabrik's 20100123 Haïti

 the last time it was modified). They are generated with a small Common

First things is when doing things with javascript is to use a debugger
tool. Firebug firefox extension is great, and the built in developer
console in Chrome/Chromium will also give you an advantage.

using these we can see that theres an error: Cannot set property
'innerHTML' of null at line 151
it's looking for a div with the id of output so stick div
id=output/output in, or delete line 151 thats giving the error.

Meridian2 and OSM comparison for march 2008 to october 09. Couldn't
see it on the lists so am sharing here :)

http://povesham.wordpress.com/2009/11/14/openstreetmap-and-ordnance-survey-meridian-2-progress-maps/

previous:
http://povesham.wordpress.com/2008/08/07/osm-quality-evaluation/
He's talked about this at some SOTMs too.

The growth within just over a year and a half  is very impressive.
Rising from 27% in March 2008 to 65% in October 2009. When attributes
are considered, it gone from 7% to 25%. Notice that the criteria that
I have set for this comparison is stringent than the one in the
previous study, so the numbers – especially for the attribute
completeness – are lower than those published in August 2008.

Looks like the full report will be out later.
Cheers Muki, love this analysis!

Re: [Talk-GB] OpenStreetMap's first flight!

[Tim Waters (chippy)]

Hi, yes was about to suggest map warper (warper.geothings.net) it can handle
oblique photos, given enough control points (which you'd need for a desktop
equivalent)

However, the server it's running on is crappy and shared and stingy on
processes that need some power, so I've had to restrict it so that its only
good for a few images where each image is about 1500x1500. Multiple images
can then be stitched together. So would be best for lots of images which can
be collaborativley rectified.

However, the code is open source, and I have another unrestrcited server
available which would be able to work with much larger images. if you would
like a bespoke online warper instance. Let me know :)

Cheers.

for rectifying maps, not oblique photos.

I have been investigating the possibilities of using something like Panorama

identifying matching points between a set of images, and using them as the
reference points for stitching sounds very appealing. If anyone knows of a
way to do this, please help.

Re: [OSM-talk] Twitter bots

[Tim Waters (chippy)]

Hi Alexander,

Nice to see it popular, however...

a few of us like to use a twitter search for openstreetmap to see
what humans are saying but recently pretty much all of the tweets we
receive for this search are from these bots.

Would it be possible to reduce the level of spam - one example could
be for the bots to use the shorturl (osm.org) or other short url
service instead of the full openstreetmap.org url?

Cheers,

Tim

2009/8/20 Alexander Klink o...@alech.de:
 Hi everyone,

 This weekend, I hacked together a quick twitter bot,
 which now tweets all changesets in a certain are (in
 my case, Darmstadt, Germany) - see http://twitter.com/osm_darmstadt

 I've found it quite useful thus far, on the one hand I write
 better changeset comments, because I know they will be on
 Twitter, on the other hand, I see what happens in my community.

 If you want to run a similar bot, you can find the source
 at http://git.alech.de/?p=osm_twitter_bots.git

 Alternatively, I can add a bit of code to run more than
 one bot at a time and run a few of them for you (until I
 hit the Twitter API limits), I'd only need a name and a
 bounding box for that.

 Cheers,
  Alex

Re: [OSM-talk] Potlatch 1.1

2009/7/11 Richard Fairhurst rich...@systemed.net:

 == Photo-mapping ==

 You can now do photo-mapping with Potlatch. Just click the camera icon, and
 it’ll talk to your favourite online photo storage service to get pictures.

 By default it uses openstreetphoto.org - so many thanks to Stefan de Konink
 (you may want to print that sentence out and frame it) for that. OSP’s
 coverage is only beginning but, coincidentally, I believe there’s some good
 pictures in Amsterdam. It reads a subset of KML, so you can set up your own
 site, and I know John McKerrell is working on one such right now.


Nice but can anyone tell us how we can add photos to OpenStreetPhoto ?

Neither the page on openstreetphoto.org nor
http://wiki.openstreetmap.org/index.php/OpenStreetPhoto gives any
detail about how us, the community can add photos to this database.

All I can find are details about how it could be implemented, and some
info about a model helicopter.

Re: [OSM-talk] Mapping party suggestion for SOTM

[Tim Waters (chippy)]

2009/7/9 Ævar Arnfjörð Bjarmason ava...@gmail.com:
 A few months ago in some local news media a talking head claimed that
 Amsterdam's Red Light District wasn't in central Amsterdam and
 moreover that it didn't contain any Coffee shops, i.e. ones of the
 type that'll sell you more than just beverages.

 So of course I headed over to OSM to prove both of these to be
 incorrect. Only to find to my disappointment that not only did the map
 of Amsterdam not have an area (or even a POI!) for the Red Light
 district, it also didn't have any sort of tagging schema for
 aforementioned Coffee shops.

 (Incidental after some searching around this is the best map I can
 find showing those two features:
 http://www.coffeeshop.freeuk.com/Map.html)

 So here's hoping that SOTM visitors to Amsterdam will be able to
 rectify this situation.

 The problem of coming up with a tagging schema for POIs applicable to
 these two categories I leave to you.


I think that would be an interesting little micro mapping party.

Brings up the subject of how to map known illegal establishments -
we should map the truth on the ground, we should map their land use as
something like brothel and recreational drug shop, in my opinion.

In a few countries, the law looks the other way, or are facing
loopholes, - the places name themselves massage parlour, coffee
shop but people passing by know what they are really for. Added to
this is the threat that these places may take offence (sue?) at being
labeled as doing illegal things (even though they may well be).

Re: [OSM-talk] Move the Map

[Tim Waters (chippy)]

One of the main annoyances that people tell me that they have with OSM
is that whenever they visit the site, the map shows them just the UK.

What are people's thoughts about the default zoom?
I'm aware that sometimes it may use a cookie and so the map will open
up to a previously viewed area - but only when logged in. At present
the website does not have a remember me / persistent login - so that
a user has to view the UK area on the map first, as a logged out user,
before manually logging in, and thereby possibly seeing the map
change.

Do you think it makes a difference what area a user views?
Would zooming based on IP Address be a good idea?
How about using cookies for non-logged in users?
How do other mapping websites do things, and are there any lessons to learn?

(One main difference on other sites is that their search box is much
more prominent)

[Talk-GB] Pateley Bridge mapping party 7th June 2009 with the AGI Northern Group SIG

[Tim Waters (chippy)]

Hi Folks,

been on the cards for a while, but we've decided on a location,
Pateley Bridge, in North Yorkshire, a nice little place, with the UK's
oldest sweet shop, apparently!

All welcome, the more the merrier.

The surrounding area needs mapping too, and there should be excellent
walks nearby.

Sunday 7th June, for one day

http://wiki.openstreetmap.org/wiki/Pateley_Bridge_Mapping_Party

If there's enough interest, lift shares / minibuses could be arranged.

It's being run In collaboration with the AGI Northern Group - sign up
on the OSM wiki, but also (its free!) sign up on the groups event page
http://www.agi.org.uk/sig/north so they can get accurate numbers.

Also, it's got 4 CPD points, for those doing profession development /
or going for their Chartered Geographer.

If you know the area, we are after a nice family friendly venue to
meet for the day, perhaps a cafe?

We may also be getting the loan of some GPS units from the Environment Agency.

Cheers!

  How much does a small plane with camera mount cost to hire for a day? :)

 I don't know about a day but 17 overlapping images of an approximately 10 by
 10 km area cost me GBP600. Once rectified they were not true plan images
 being slightly oblique. I guess the best images would be taken higher ( mine
 were 14000ft IIRC) with a longer lens to reduce parallax errors.

 It depends on wether you're going to invite the pilot for a nice
 meal  :-)
 I think the most tricky part of the story is still to rectify and
 adjust the resulting aerial imagery. If you managed to develop a
 procedure for this step, please let me know  ;-)

 Jukka Rahkonen showed me how to do it with gdal_translate and gdalwarp. It's a
 lot easier than it looks at first.

 Essentially the first bit burns ground control points into the image the
 second then stretches the image and produces a geoTIFF from it. I visited 4
 ground control points with my GPS each about 3km apart and at prominent
 points near the corners of each image. I suggest you need farm ore ground
 control points than this at this scale because my georectified image was up
 to 20 metres adrift in some parts.

Indeed it's quite easy, at the basic level you can use a similar
service such as http://warper.geothings.net or choose from a desktop
GIS, most of them have some way of doing this. These would georectify
images, but we should orthorectify them too which is a bit more
trickier.

What happens is that the distance from lens to ground is different
over varying terrain, so it doesn't match what a map would be.

Crudely, imagine taking a snapshot photo from the plane just as you
fly over a mountain top: way down below you'd see the tiny roads, but
most of the frame would be the mountain peak. Of course,
orthorectification is more important with terrain at different
heights, and less so for flat ones.

I think the way these are done are to use a digital evevation model -
I would hope the free SRTM could be sufficient?

Re: [Talk-GB] Route planner using UK OSM data

[Tim Waters (chippy)]

Hi Andrew,

This is really neat. it's good to see a few excellent routers occuring
because of OSM.
I think your one is quite powerful for the ability to customise the
weighting, nice!

Also, any plans to release the source for the router available so we
can play too?

Tim

2009/3/22 Andrew M. Bishop a...@gedanken.demon.co.uk:
 I have been a contributor to OpenStreetMap for a while now and
 recently decided to make use of some of the collected data rather than
 just adding to it.

 I decided that what would be fun to implement is a routing algorithm
 that can find the best (shortest or quickest) route between any two
 OSM highway nodes.  I know that there are other routing algorithms
 available but this started as an intellectual exercise so I developed
 my own.  It seemed to work so I added a fancy web front end to it and
 put it on a server.

 Having the complete planet routable was infeasible so I have just
 included the data for Ireland and Great Britain.

 You can select from any of the major OSM transport types (foot,
 bicycle, horse, motorbike, motorcar, goods, hgv, psv).  For each of
 the OSM highway types (motorway, trunk, primary, secondary, tertiary,
 unclassified, residential, service, track, bridleway, cycleway,
 footway) you can select whether to use them and if so what speed
 limit.  Restrictions on one-way streets, weight, height, width and
 length are also options.

 The router takes into account private/public/permissive restrictions
 on highways as well as tagged speed limits.  What it doesn't do is
 barriers (gates, bollards) and turn restriction relations (which I
 have heard about but never seen).


 The router itself (requires JavaScript for the map etc):

Re: [OSM-talk] Call for Papers for SOTM09 is now open

[Tim Waters (chippy)]

Thanks Nick,

for the clarification - it's certainly looking like it's going to be a
cracking conference!

chippy

2009/3/16 Nick Black nickbla...@gmail.com:
 Hi Chippy,

 The idea of the business day is to promote OSM and opengeodata to potential
 users.  The business day is not so much about letting OSM solution providers
 promote their products.  We want to focus on the bigger issues - why OSM is
 important to consumers of geodata, why crowd sourcing is the way forward,
 reliability of OSM etc.  We are planning a 10 of the best session - a one
 hour slot that would let startups and small businesses pitch their solution
 to the audience.

 The SOTM organizing committee are currently finalizing the themes and
 agenda, but this is what we are looking like at the moment:

 Suggested Themes:

 Crucially Independent - Why an independent third data source is vital for
 consumers of geodata
 The Crowd Sourced Advantage - What is crowd sourcing and how does it relate
 to map data?
 Safe and Secure - Delivering reliable, high quality products and services
 with OSM data
 Serving the Public - Using OSM data to provide better services to citizens
 in Local and National Government

 Criteria for Choosing Speakers

 World leader in a field that is directly relevant to a theme
 Senior level in a company that is contributing to the themes of the day

 Target Audience

 Execs and senior management from mobile handset manufacturers, network
 operators, transport consultancies, national and local government, web
 portals, navigation providers and other ISVs using mapping data
 Professional cartographers, GIS analysts and statisticians
 Owners of start-ups and small businesses who use or are considering using
 mapping data
 OSMers (of course ;-) )

 Concept program

 Show the problem - why do you need crowd sourced data?
 Introduce the solution - OSM - crowdsourced, reliable, up to date
 Give examples - people using OSM data
 Discussion panel - panel made up of leading speakers for the day

 The quick answer is that you should first submit to the weekend conference,
 via the online form.  When the Biz Day is finalised (in the next few days)
 you can always re-submit or submit a second paper.

 Cheers,

A few points to throw in the mix:

* Do we have people who want to write a blog for the project as a
whole?  - Blogging requires quite a bit of commitment, especially for
such a fast moving project, if things get busy elsewhere, the blogs
tend to suffer.

* Assuming we have enough people interested, should we have some kind
of editorial policy (i.e. no Wee Poo Street notifications, or max
two LOLcat pictures a month)?

* If we create a new blog - can/should we import the relevant tagged
entries from opengeodata?

* Can we simply rename opengeodata or point to blog subdomain? (Where
is it hosted?)

[OSM-talk] New Map Warper

[Tim Waters (chippy)]

Hi,

I'd like to announce the release of the latest Map Warper image
rectifier application, designed with OSM in mind.
http://warper.geothings.net/

You may have seen or used the older application, this one has got a
few more bells and whistles, including:
* Search for maps.
* Users  MyMaps. (no need to sign up to use it)
* Image cropping.
* Control Point editing.
* Calculation of RMS errors.
* Export in different formats.
* Activity feeds.

More info: http://thinkwhere.wordpress.com/2009/02/10/new-map-warper/

Caveats: It will rescale large images (over 1500x1500), but it also
makes things work much faster. It is ultra-beta and undergoing active
development, so expect bugs and things not to work, but for most uses
it should work fine. Let me know if you encounter any such things.
If you have any existing WMS links from the older version, they will
still work and I've also imported the existing maps, and control
points. If you sign up and want to own a map you previously
uploaded, let me know.

Features planned include serving the rectified maps as tiles, adding
tags, making maps private, making the KML export better, and
incorporating GeoRSS feeds. Again, feel free to drop me a line if you
have a good idea for a new feature, or if you'd like to hack on it.

Uses OpenLayers, GDAL, Mapserver and RubyOnRails, source can be found
http://svn2.geothings/net/mapwarper or
http://github.com/timwaters/mapwarper

Cheers,

Tim

Incidentally, what do we think about using Google's Satellite View for
helping to rectify our maps?
In the comments of Ed Parsons post
http://www.edparsons.com/2008/10/who-map-is-it-anyway/ there was a
discussion about Google's rights over things you make using their API,
and I think Ed is making it clear that using the Satellite view to
rectify images for this application would be quite OK, giving the
similar use case of adding an image to Google Earth and I'm inclined
to agree with him.

 Caveats: It will rescale large images (over 1500x1500), but it also
 makes things work much faster. It is ultra-beta and undergoing active
 development, so expect bugs and things not to work, but for most uses
 it should work fine. Let me know if you encounter any such things.
 If you have any existing WMS links from the older version, they will
 still work and I've also imported the existing maps, and control
 points. If you sign up and want to own a map you previously
 uploaded, let me know.

 Features planned include serving the rectified maps as tiles, adding
 tags, making maps private, making the KML export better, and
 incorporating GeoRSS feeds. Again, feel free to drop me a line if you
 have a good idea for a new feature, or if you'd like to hack on it.

 These new features are very useful, especially the ones to do with
 user accounts, it's nice to have a list of your maps instead of just
 adding them to one giant pool.

 I think the map rectifier is a bit less intuitive than in the previous
 version. I used to be able to double click on either map which would
 add a new rectification point and then do the same with the other map,
 but now one has to switch between the Add point/Move point/Move map
 tools to move around the map. This has the advantage of being able to
 double click on the map in move mode without adding points (and
 probably something else I'm missing). But switching between the
 different modes took me bit longer using this method.

Yes, I'd agree with you there, the reasoning is that people tend to
use double click to zoom in, but I think that double clicking should
make it a bit easier. Will look into it.

 Also, being able to download GeoTiff from the application is a very
 useful feature, but does it also support GeoTiff uploads? That would
 enable moving maps between installations and using this as a easy to
 set up WMS for misc GeoTiff files.

At the moment, I don't think it likes geotiff files that have already
been rectified, but you could try with a small one... Anyhow, the
approach I would take is to strip out any original geo tags from the
image, and so you would have to add a few control points and warp it
again.
It's not really meant to be a WMS host for ready made GeoTiff files,
but I may put a simple upload-a-tif-and-host-it service anyhow, as you
are not the first person to ask for this.
 (JOSM import support for reading geotiffs would rock).

 The biggest disadvantage of this tool is still being limited by the
 size of maps you can upload. I have several ~6000x~5000 pixel maps I'd
 like to have access to over WMS, each around 12 MB[1]. Is there any
 reason for this limitation other than preventing the application from
 taking over resources on your server? Or is it a limitation of some
 library you're working with?

Yes, this is Dreamhost, they have a script that will terminate
processes using a lot of CPU or RAM, so I can add a couple of
restrictions (file size and image dimensions). You may like to have a
look at another deploy over at http://warper.freemap.in for larger
files. We're going to be warping 800mb tifs soon... here, the main
limitation is that you can expect http timeouts for very large
uploads.


Cheers!

2009/2/11 Someoneelse li...@mail.atownsend.org.uk:

 One thing that might be useful would be some sort of My OSM or a
 saved play mode feature* -

Now, that would be an interesting idea  - being able to access all
your edits and the history of these in one place.

Worth mentioning that geofabrik makes very regular exports of railways

[Tim Waters (chippy)]

Hi,

In what I hope will be the first of many regular meet-ups throughout
the North, just a little reminder about the upcoming meet-up at the
Scarborough Hotel, in Leeds, at 3pm this Sunday the 25th Jan.

Look out for geeks with GPS units and maps!

The pub is located just outside the train station:

 Persuading the author to put up a big reminder at the top of the page
 saying OSM users: please upload only to private osm-api servers or
 somesuch might be more useful. The tool is presumably useful outside OSM!

Well even so, it would probably be against the terms of use etc from
Google, and they can ask for it to be taken down, so whilst it may be
useful, it cannot be used...

That saying, whilst it would apply to Google, it wouldn't be for everything.
The tool could be used for other tiled layers - something of much greater use.

[OSM-talk] OpenSantaMap

[Tim Waters (chippy)]

One of the main strengths of OpenStreetMap is that we have access to
the raw data, and one of the best ways we can illustrate this power,
whilst also reinforcing the idea that the map is just a rendering of
the data, is to create custom renders.

Great examples of these are the Mapnik and ti...@home maps,
Cloudmade's mobile tiles,  and of course the award winning
OpenCycleMap.

And now, as there has been some talk about a fun seasonal render,
OpenSantaMap, I have started a wiki page for us to add our thoughts.

http://wiki.openstreetmap.org/wiki/OpenSantaMap

Some ideas to get the (snow)ball rolling:

Snowflake background.
Using the Unicode snowman character ☃ .
Changing colours to more gaudy red/green scheme.
