Yes, all category, user and post links still work by redirecting to
the imported content on community.openstreetmap.org
The redirect logic is explained here:
https://community.openstreetmap.org/t/migrating-content-from-old-forums/446/214
The thread also has details how you can check the logic yourself.

The RSS/Atom feeds for the old forum will not be redirected, but will
be pointed at a static feed asking users to update their feed links.

[OSM-talk] Test Import of forum.osm.org to community.osm.org

[Grant Slater]

Hi OSM Talk,

In the near future we will be moving the old forum.osm.org content to
community.openstreetmap.org

If you used the old forum, please login to the test import site
https://forum-import-test.openstreetmap.org/ to check your old posts.

The imported content is at the bottom half of the test import site.
The database snapshot used for the test is from 02 Feb 2023.

The old forum has 847000+ posts by 35000+ users in 91 categories. The
longest thread has 14700+ posts!
The old forum used fluxbb bbcode markdown, while
community.openstreetmap.org uses discourse's flavour of markdown.
The import markdown conversion can never be 100%, but it now appears
to have reached "good enough".

We heavily extended the original fluxbb discourse importer with
additional features:
* Significantly improved fluxbb bbcode -> discourse markdown
converter, including fixes.
* Added Permalink support (To test for now use old forum url path +
parameters on forum-import-test.openstreetmap.org)
* OSM specific old forum to community account merging allowing
seamless login using osm.org account oauth flow.
* Added unit tests

We are trying to contribute the improvements upstream where appropriate.

There will also be a few tasks the forum governance team will be
responsible for post final import, notably:
* Manually merge duplicate categories (eg: country categories)
* Mark old abandoned categories as read-only.
* Manually merge duplicate users where the importer did not
automatically merge (very limited cases).

Big thank you to Harry Wood, Tom Hughes and others who have helped
write code, fix bugs or assisted in other ways.

Kind regards,

Re: [OSM-talk] AT Email

[Grant Slater]

Hi Mike,

We have now reached out to ATT asking them to unblock the
OpenStreetMap.org mail relay server or provide us with more detail.

We recently cut across to a new email relay server, we had spent a few
months slowly increasing the mail sent by the new relay to slowly
build up "sender IP reputation".

Re: [OSM-talk-nl] Gedoe rond garmin.openstreetmap.nl

[Grant Slater]

Hi OSM NL,

Sorry dat ik in het Engels schrijf. Ik betwijfel of mijn Afrikaans
hier wordt begrepen ;-)

I think Stefan is referring me to contacting uni-wuppertal.de to ask
if they could put me into contact with the person who runs the backend
of garmin.opensteetmap.nl (osm.pleiades.uni-wuppertal.de). I asked if
they are unable to put me into contact with the person if they'd
consider redirecting the service to
https://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/Download
garmin.openstreetmap.nl has been offline for I think around 2 years
(and disrupted long before then). Despite the service not functioning,
it still used to accept map requests and told users to wait for an
email. The service still accepts donations despite being abandoned
(>£8000 Bitcoin received).
The service should be maintained else shutdown for the health of
OpenStreetMap. The OSM Operations
Group and Data Working Group have received misdirected complaints
about the service in the past.

For background see: https://github.com/openstreetmap/operations/issues/615

This all feels like the painful process I had to go through to get
forum.osm.org transferred a few years back.

I am an OpenStreetMap.org sysadmin first and have been a volunteer
sysadmin for over 15 years. I care about OpenStreetMap first before my
new employer.

Kind regards,

Grant

[Talk-GB] Finally a RTK / NTRIP Broadcaster in London

[Grant Slater]

Hi All,

Experimenting with RTK? (rtklib)
Need an NTRIP / RTCM broadcaster in London?

Great news, there is finally a free one available!
Registration required here:
https://register.rtcm-ntrip.org/cgi-bin/registration.cgi

Others available in the UK:
DARE00GBR0: Daresbury
ENIS00GBR0: Enniskillen
FOYL00GBR0: Londonderry
HERS00GBR0: Herstmonceux
HERT00GBR0: Hailsham
INVR00GBR0: Inverness
LICC00GBR0: London
SHOE00GBR0: Shoeburyness

RTK is a way to get ultra precision (~1cm) "GPS" position.
The cost of the required receives have plummeted in the last few years.
< €300 now for a basic receiver and antenna.

[Grant Slater]

Hi OpenStreetMap NL,

Would anyone like 4x HP DL360 G6 Servers?
Example Specs: 
https://hardware.openstreetmap.org/servers/spike-02.openstreetmap.org/

They are great reliable 1U servers and served OpenStreetMap.org very
well for the last few years.

They are free. Collection is from Amsterdam at whatever time is
suitable for the person collecting them. They will be ready for
collection in around 2 weeks time. They need to be collected in person
and not suitable for collection by a courier. Collection needs to be
all 4 servers at once.

Yes, on a brief inspection it does look like it is OpenStreetMap data.
Sourced some time between sometime between 27 July 2017 and 14 March
2018.
Looks like they also directly used the names of prisons.
Example: "HMP Isle of Wight (Albany)"

Maybe they should donate a few survey drones to OpenStreetMap
Foundation as recompense and fix their attribution going forward.

Re: [talk-au] [Talk-nz] Able to host a tile.osm.org CDN node?

[Grant Slater]

Hi John,

We have universities, internet exchanges, hosting companies and some
individuals which host servers for us.
The full list is here: https://hardware.openstreetmap.org/thanks/

We fully manage the software and operating system. All config is
managed via our chef https://github.com/openstreetmap/chef . We also
run a local firewall on each server. If physical hardware, we monitor
using it SMART, hp-health, etc and report any hardware issues back to
the hosting organisation.

AWS bandwidth is extremely expensive and is unlikely to be the most
effective way of improving OpenStreetMap. Most of the bandwidth used
by a regional tile cache is "local". We've had hosting and Internet
Exchanges who have appreciated hosting these caches, because they've
then been able to negotiate better peering agreements with others.

Kind regards,

Grant

Hi OpenStreetMap Talk-BR,

(Please would someone kindly translate this into Portugês?)

Quick Introduction: I am part of the volunteer Operations team who run

Our tile.openstreetmap.org CDN would greatly benefit from having a
cache server in Brazil.
It would make the default rendered map on OpenStreetMap.org much
faster for Brazilians.

The live CDN Country -> Edge Cache Mapping:
https://dns.openstreetmap.org/tile.openstreetmap.org.html

Know anyone who could help?
We're ideally looking for a dedicated physical server or powerful VM with 8GB+
RAM and at least 146GB of storage.
More details here: https://wiki.openstreetmap.org/wiki/Servers/Tile_CDN

[OSM-talk] Crowdsourcing purchase of Historical Namibian Topo Maps

[Grant Slater]

Hi All,

I am running a GoFundMe campaign to purchase the historical 1:50k
topographic map series for Namibia.

Any support would be appreciated:
https://www.gofundme.com/namibian-topographic-maps

The map sheets were produced during the 1970s and 1980s by the
Surveyor-General of South West Africa, along with the South African
Chief Directorate Surveys & Mapping. They comprehensively mapped South
West Africa and produced 1218 1:5 Topographic Map sheets covering
the whole country.

It is now very difficult to find a complete set of these sheets,
thankfully a commercial project in the mid 2000s were able to collect
and scan these invaluable sheets and they are willing to sell me a
digital copy of their scans.

Namibia gained its independence in 1990 from South Africa and some
time later the South African government mapping agency gifted all
their Namibian sheets to the new Namibian government mapping agency.
It is now unclear who own the rights for these sheets. Both
governments seem to claim the other owns the rights, with neither
assert them. The sheets have been freely used by humanitarian
organisations in the past.
It is my belief that we may freely use the sheets for deriving
information for OpenStreetMap mapping purposes.
We already have permission to use the South African topo series see
https://www.openstreetmap.org/copyright &
https://htonl.dev.openstreetmap.org/ngi-tiles/

I have some samples here:
https://grant.dev.openstreetmap.org/namibia-topo-50k/
and a scaled copy of a full sheet here:

Re: [OSM-talk] API a lot slower?

[Grant Slater]

Hi All,

Yes, the API will be slower. We are running on our backup hardware for
the next few weeks.

Our primary hardware is moving to a new data centre next week, and
will take some time to get up and running.
It is a major move for the server operations group. Will announce more
details in the next few days.

Kind regards,

Grant

Re: [talk-au] Increased precision options for Australia - QZSS, SBAS or Galileo

[Grant Slater]

Hi All,

I have 2 of these for RTK GNSS receivers: https://emlid.com/reachrs/

1 ReachRS unit becomes the RTK static "base" and you needs a very
accurate position measurement and good signal. To get the most
accurate measurement I use my base and connect it to another base
using an NTRIP network. I'm in the United Kingdom and I connect to the
free NTRIP network available here: http://www.euref-ip.net/home . I've
also used the South African free NTRIP network trignet.co.za
Geoscience Australia seem to offer a NTRIP network here:
https://www.auscors.ga.gov.au/
Note that max workable distance between base and rover is only around
20km. I've got it to work at 80km, but needs exceptionally clear area
(unobstructed sky) and a lot of patience to get the position fix.

Once I have my static ReachRS measured, I then connect it up to the
2nd ReachRS as a roving unit via built-in radio or Cellphone. A
reasonable maximum distance between Base and Rover is around 20km.

The rover is good for measuring points, but starts to struggle if
moved above walking pace or has an obstructed sky (read: trees etc)
Repeatable accuracy is <10cm horizontal and similar vertical.

It is possible to do the above with a single unit if you can rely on
an existing NTRIP network, but I believe you then cannot then use the
GLONASS network for getting a fix due to different antenna types
between base and rover.

The ReachRS is a single frequency receiver and needs better signal and
is slower to sync than a dual frequency receiver. In the next year or
2 there are likely to be more dual frequency receivers from the likes
of u-blox. The swiftnav.com unit looks interesting.

The ReachRS receiver uses a u-blox Neo-M8T chip and the rtklib
software. A homebrew alternative would be to use
http://www.csgshop.com/product.php?id_product=257 and rtklib yourself.
See: https://www.blackdotgnss.com/2017/03/25/u-blox-neo-m8t-part-i/

Interest? Highly recommend blog: https://rtklibexplorer.wordpress.com/

Kind regards,

Grant

OpenStreetMap.org services are abused precisely because the are 1)
Free to use, 2) they are open to use (no keys etc) and 3) for most
part we don't actually limits the usage of the services (There isn't
actually a 5% cap on tiles).
I'd feel uncomfortable with an Open Data project charging for services.

I'm a reasonably good sysadmin, but people smarter than me need to
decide on the direction of the project. ;-)

Interesting parallel discussion thread going on on twitter, maybe OSMF
should be "willing to pay a developer a market-rate salary to own this
problem" using some of the Pineapple Fund donation:
Jumping off point: https://twitter.com/richardf/status/965301288933175296

I'd be all for that.

Let's Encrypt is a "charity" and is "begging for handouts", but is

last 2 years. I don't think OpenStreetMap needs to become a commercial
project to survive.

Not great. :-(

Nominatim effectively only has 1 maintainer / primary contributor:
https://github.com/openstreetmap/Nominatim/graphs/contributors
lonvia spends a significant amount of her volunteered time defending
the service again abusers.
https://operations.osmfoundation.org/policies/nominatim/
Single users can overload nominatim by sending 1000s of automated
requests per second, the same holds true for the tile servers we run:
https://operations.osmfoundation.org/policies/tiles/

Nearly as bad contribution wise is the server infrastructure code:
https://github.com/openstreetmap/chef/graphs/contributors

What we badly need is more help from developers and chef operations people.

How about someone in the community organises a Beauty Parade / Cross
Comparison of different open OpenStreetMap GeoCoders?

The OpenStreetMap Operations team prefers to be able to self-host the
infrastructure required to run OpenStreetMap.org. Reasons: Privacy /
Maintainability / Availability. We don't go this route for a
navigation / router as they seem to be under constant flux, without a
clear "winner" and system their requirements keep climbing.

Kind regards,

Grant

[Talk-GB] RTK / Base Stations / NTRIP

[Grant Slater]

Hi OSM GB,

I've recently been experimenting with Real-time Kinematic (RTK) "GPS"
GNSS receivers and RTKLIB with some reasonable success. I've been able
to get repeatable centimetre level position accuracy.
I've been using u-blox NEO-M8T chipsets.

Unfortunately there are very few open and realtime RTK/RTCM NTRIP
streams available in the UK.
The lack of access to a reasonably nearby stream limits the RTK to
mostly post-processing application.

The open live streams I have found for the UK are at Daresbury,
Inverness, Shoeburyness. All of which are in excess of 70km from where
I live.

OS Net has good coverage, but is commercial. They do provide open
access RINEX post processing data, 24 hours after capture:
https://www.ordnancesurvey.co.uk/gps/os-net-rinex-data/

I'd be interested to know if anyone else has been experimenting with RTK?

Do you need a live RTCM stream for experimenting / survey? I can
create one, happy to travel closer on the weekends too. I use a Emlid
Reach RS.

Kind regards,
Grant

Someone should mentioned to the Pokémon players that if they correctly

[OSM-talk] OSM Forum move / disruption

[Grant Slater]

Hi All,

The OpenStreetMap forum at http://forum.openstreetmap.org/ is moving
to a new server this Saturday. During the move the site will be
disrupted.

The move is scheduled for the United Kingdom morning. (GMT+1)

All content and users will be migrated. After the move the forum will
be https by default (with redirect).

In the not too distant future we'd like to find a suitable volunteer
forum admin. The ideal person would be level headed and would also be
responsible for maintaining / patching the forum's codebase:
https://github.com/openstreetmap/openstreetmap-forum

A big thank you to Lambertus for his running of the OpenStreetMap
forum for many years. The move is being performed with his agreement.

Kind regards,

Re: [OSM-Talk-ZA] High Resolution Aerial Imagery of Cape Town (8cm)

[Grant Slater]

Dawid, I have tried to get aerial imagery from Joburg Metro
Municipality but they wanted to charge me R20k+ for the imagery.
Ekurhuleni was similar. Port Elizabeth (Nelson Mandela Bay
municipality), East London (Buffalo City Metropolitan) & Durban
(eThekwini Metro Municipality) have similar aerial imagery, but I
haven't yet found the right channel to request the imagery.

CoCT initial wanted to charge similar, but I was able to negotiate
special permission for OpenStreetMap. I also have the 2013 imagery.
They are busy working on 2016 imagery, but wasn't able to get
permission for this imagery (yet).

On http://coct.aerial.openstreetmap.org.za/ if you select the "DRIFT
TEST" layer, this has continental drift correction. The African
continental plate is drifting North East at around 3cm per year. The
co-ordinate system that City of Cape Town uses the fixed position of
the Hartbeeshoek Radio Telescope as the co-ordinate origin.
OpenStreetMap uses WGS84. I'll remove "DRIFT TEST" option this evening
and make it the default. Yes, this does mean OSM co-ordinates drift
out around 3cm per year..., same for the UK... Around 7cm per year for
Australia, I'm sure we'll work out a solution at stage, when most of
us are mapping at this kind of crazy resolution.

I'll get the imagery added to iD and JOSM in a few days, until then
feel free to add it manually. Please use tag source=coct-2015

Kind regards,

Grant

[OSM-Talk-ZA] High Resolution Aerial Imagery of Cape Town (8cm)

[Grant Slater]

Hi OpenStreetMap ZA,

I've been able to get permission for OpenStreetMap to use the City of
Cape Town's very high resolution 2015 aerial imagery (8cm). I
collected a copy of the imagery last month.

It will be available in JOSM and iD in a few weeks time.

In the mean time, here is a quick preview:
http://coct.aerial.openstreetmap.org.za/

The imagery is expressly ONLY FOR OPENSTREETMAP USAGE. I would have
preferred it be open to all, but wasn't able to negotiate this with
CoCT.
Note CoCT list the imagery on their Open Data portal:
https://web1.capetown.gov.za/web1/OpenDataPortal/DatasetDetail?DatasetName=Aerial%20photography

Due to continental drift and the conversion between Hartbeeshoek94 and
WGS84 (as used by OSM) the imagery is *currently* around 66cm offset
(2016 - 1994 = 22 years. Drift ~3cm per year). I am busy processing
the imagery to correct this, hence the delay in getting it into OSM
editors.

Kind regards,

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

[Grant Slater]

Hi OSM-GB,

The Environment Agency recently release a massive trove of Open Data,
which I am slowly started to process.

One of the smaller and quicker to process datasets is the Night Time
aerial imagery which I've now tiled and put online here:
http://ea.openstreetmap.org.uk/

Birmingham: http://ea.openstreetmap.org.uk/#zoom=12=52.4831=-1.8772
Peterborough: http://ea.openstreetmap.org.uk/#zoom=13=52.5743=-0.2588
Northhampton: http://ea.openstreetmap.org.uk/#zoom=13=52.2458=-0.8871
Swindon: http://ea.openstreetmap.org.uk/#zoom=13=51.5793=-1.7931
London (Mostly South):
http://ea.openstreetmap.org.uk/#zoom=11=51.5266=-0.0636

Unsure how useful the Night Time aerial imagery is for OpenStreetMap
proposes, but it sure does look good ;-)

[Talk-GB] Updated OS Street View (OpenData)

[Grant Slater]

Hi OSM-GB,

I recently updated:
http://os.openstreetmap.org/

The site now has all the OS Street View OpenData editions April 2010
to April 2016.
The tiles defaults to the latest April 2016 edition.

Ordnance Survey are not releasing further updates to OS Street View. [1]

I have created "diffs" which highlight changes between each edition,
these are helpful to find what has changed and possibly where to focus
OpenStreetMap mapping expeditions.

The diffs took over 224 days of CPU time to produce on a reasonably
fast Intel Xeon CPU. I hope people find them useful ;-)

PS: Currently there is no permalink feature... Would love it if
someone else added this feature ;-)
templates + files here contain the leafletjs + html code:

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

[Grant Slater]

Hi All,

On Monday 9th May 2016 the master OSM database server was moved to
York (Bytemark) from London (Imperial).
This was to avoid multiple upcoming weekends of planned power testing
& maintenance at the Imperial data centre. For the last few years
Imperial has housed all our main critical systems including master &
slave DB servers and frontend & backend web/api servers. We also added
4 new frontend/backend web/api server to York on Monday.

We now have the master database server in York and the secondary
database server in Imperial. We also have a warm standby slave db in
AWS Ireland. A fourth SSD (NVMe) based DB server was delivered
yesterday (Thursday), but it needs testing (burn-in, reliability,
performance etc) before we can start using it. Slave DB servers can be
promoted to master if required.

The slave db servers serve Web/API read traffic and writes go to the
master. When the frontend + backend servers were in the same data
centre as the master db server the latency was <1ms. We now run a VPN
to connect the servers up and the latency is ~8ms Imperial to
Bytemark. Currently we are using the frontend & backends server at
Imperial (closest to slave db read server) and sending writes over the
VPN to Bytemark. The extra 8ms roundtrip is triggered multiple times
based on the size of the upload changeset, this is the root cause for
the slower uploads. The link between Imperial & Bytemark can handle
gigabit speeds. Over the last few days we've been tweaking the VPN
settings to get optimal latency & throughput over the links.

Over today (for at least the weekend) we are switching to the new
frontend & backend servers in York (Bytemark). London Imperial will be
offline from approximately 5pm (GMT+1) for the first weekend of power
maintenance.

In summary: The slow uploads are a known issue and we'll fix as soon
as practical. Our main concern has been setting up multiple data
center redundancy to avoid extended downtime.

Here is the list of all core hardware and hosting locations:
https://hardware.openstreetmap.org/

Hope that answers the questions. ;-)

Photos or it didn't happen:
* Syncing & powering down before we start London -> York DB move:

* Staged photo of racking up the master DB server at Bytemark:

* Testing the new Frontend / Backend servers a week ago:
https://twitter.com/OSM_Tech/status/728286193696292865

Bytemark are a fantastic hosting company and their ongoing support of
the OpenStreetMap project is highly commendable. Please support them

[OSM-talk] Upcoming Planned outage - 9th May 2016

[Grant Slater]

Hi All,

On the 9th of May 2016 the primary OpenStreetMap database will be
read-only for important maintenance. Editing the map will not be
possible during the maintenance.

Full announcement is available here:
https://blog.openstreetmap.org/2016/05/02/planned-server-outage-9th-may/

The Operations Working Group are in the process of planning some
hardware moves as a result of maintenance at our primary datacentre.
The plans are subject to change, but these moves are expected to take
place on Monday 9th May (a week from today), and this will mean a
period of read only operation lasting for up to 24 hours (into
Tuesday).

The read-only period will mean the OpenStreetMap website and map is
still available, but no map editing will be possible during this time.

The https://wiki.openstreetmap.org/wiki/2016_May_server_maintenance
wiki page has some more technical details, and will be updated with
more precise timing information as the plans are finalised in the
coming days.

We’re putting out this announcement to give some advanced notice, but
we appreciate some people will be wanting to know more about the exact
timings of the read-only period. Please have patience. The Operations
Working Group are busy making plans, and will aim to firm things up in
the coming days.

Kind regards,

Grant

[talk-au] AGRI Imagery

Hi Talk-AU,

I'm still working to fully restore the Australian Geographic Reference
Image (AGRI) site I run after the hardware failure...
AGRI? https://wiki.openstreetmap.org/wiki/Australian_Geographic_Reference_Image

I now have the tiles up and running again and they can be used in the
editors JOSM / iD or similar.

Issues still to resolve:
 * Currently no web interface to access the tiles.
 * Large black stripes over the overlapping sections of the imagery.
 * Poor performance, currently no caching.

I hope to fix the remaining issues over the next few weeks.

Technical:
The code used for serving the imagery is managed using opscode chef:

Agreed. I am only really setup to handle imagery/maps which have known
coordinates and projections. Maps with custom or eccentric

 OSMF is not a charity, so there is no charity number.


For clarity... OpenStreetMap Foundation is registered as a

Becoming a charity would be a significant burden on the

 be some kind of load-balancing.

 probably doing more harm than good by preventing caching.


Nope. The tiles server alias (a,b,c) are selected using a hashing
algorithm which always selects the same alias for the same tile:
https://github.com/Leaflet/Leaflet/blob/master/src/layer/tile/TileLayer.js#L134
(also applies to OpenLayers).

Overdue me explaining how the OpenStreetMap Tile CDN works:

We have 16 distributed edge cache servers all over the world [1],[2],[3].
These cache servers are monitored in near realtime by pingdom for outages.
We use GeoDNS [4] for [a|b|c].tile.openstreetmap.org which points a
client to the closest or preferred cache server for the client's
region. [5]
We rebuild [6] the GeoDNS when pingdom notices an outage, visitors are
moved across shortly once their DNS TTL has expired (~5mins)
The cache servers use 2 backend rendering servers (orm + yevaud), with
one being the preferred server [7] (cache hot path). We monitor the
backends similarly with pingdom and GeoDNS updates.

The cache servers have a fairness algorithm (token bucket) which
ensures that no single client / network can degrade the service for
others.

The 2x backend rendering servers are near perpetually overloaded,
particularly during style updates. The short-term solution would be to
add in an additional rendering server, but longer term it would be
better to move to a model where tiles (png) are rendered on the edge
cache servers with the backend servers producing vector tiles which
are pulled by the edge cache servers. There are a few people working
on this, but no complete working open source solution ready to go.
Some of us on the OSM operations team + a team from Wikimedia are
watching developments closely. ;-)

 In the absence of blatant vandalism or base abuse, I would have
 expected, first, a recent, clear and unequivocal warning on the user's
 talk page, with a suitably direct subject heading (Warning: you may
 be blocked from editing, or suchlike), and a statement of what the
 user should do differently, or not do, in order to avoid the bock.

 I do not think discussions which might reasonably be interpreted as
 mere differences of opinion, as currently seen on Xxzme's talk page,
 suffice in this regard. Likewise the four-month old notice from
 January (where, I note, Xxzme's question went unanswered)

 We might also consider imposing edit restrictions (e.g. You may not
 move pages; you will be blocked if you edit war; this will be reviewed
 after 3 months).

 Once a block has been made, I would also expect a notice to be placed
 on their talk page, stating clearly why, how to appeal, and how to
 request an unblock (You may be unblocked if you give a statement that
 you will not do X again).

 Finally since the current bock includes email disabled, cannot edit
 own talk page (were either of those privileges ever abused? If not,
 that part of the block should be rescinded ASAP.), it does not seem
 possible for Xxzme to discuss how they might make a return to
 productive editing.

 Hi all,

 I'm looking forward to OSM's 10th birthday. It occurred to me that we
 should perhaps use it as a potential opportunity for some press
 coverage, ideally to get press coverage outside the usual tech/gis
 world. To do this we'd need some kind of event which makes a story.

 There are already plans for OSM birthday celebrations/meetups, and
 that's all good. I'm NOT talking about a social event but some event,
 perhaps even just brief, as long as it's got something that might
 appeal in a soft-news kind of sense. And maybe in London, since London
 is the birthplace of OSM.

 A couple of ideas:

 * We could organise a march following the route of the first ever GPS
 track (carrying Steve Coast aloft, sitting crosslegged on a splashmap)

 * We could visit the first ever tea-shop added to OSM, then the first
 ever park, then of course the first ever pub. We could give a plaque
 to each place to commemorate its place in history.

 To make it a press-worthy event, it needs to be something that we can
 write a press-release about in advance, and it needs to be something
 photogenic. So let's get more creative...

 * We could 3D-print a candle in the shape of all the OSM nodes in
 London! and put it on top of an earth-shaped cake!

 * We could print out a map of London at 1:1 scale...

 Anyone interested in working on something? Anyone got crazier ideas than me?

* Slower map updates / Reduced tile rendering capacity. (Yevaud outage)
* OSM Foundation websites and blog.openstreetmap.org will be unavailable.
* Taginfo (taginfo.openstreetmap.org) will be unavailable.
* Development Server (errol) will be unavailable.
* Some imagery services will be unavailable. (GPX Render, OS
Streetview, OOC, AGRI, CD:NGI aerial)

Other OpenStreetMap provided services should not be affected - all of
the following are expected to function normally:

* www.openstreetmap.org web site WILL allow edits as per normal (iD or
Potlatch).
* API will allow map editing (using iD, JOSM, Merkaartor etc.)
* Forum
* trac (bug-tracker)
* help.openstreetmap.org
* tile serving (View The Map  Export)

Awesome! Do it, we are still lacking the locations of most of the Gautrain

 Two questions:

 1) What permissions do we need to get for this to be usable on OSM?

It isn't a huge dataset, so I think a simple email or document from them
saying we (OpenStreetMap) may us the data would be sufficient. Forward the
approval email to me gr...@osmfoundation.org or le...@osmfoundation.org for
archiving.

 2) Is there someone who could assist to bulk load the data.


Yes, I would be more than happy to convert to OSM format from whatever they
give you. (Even an excel document with lat/lon columns would be good)

 On the second point I would be happy to do some preprocessing. e.g.
Correlation against against a list of what has already been captured.


Once converted you can help me merge the data ;-)

 Copyright law cannot prohibit the manual reconstruction of

 Gerhardus' method is more in the spirit of OpenStreetMap though - as
OSM frowns upon the copying of information from commercial or proprietary

 Ultimately - nobody will even know: there is no
legalistically-distinguishable difference between adding something because
you were there, vs adding something because you saw it on another map.
(Obviously you should only add things to the map that you have verified
actually exists.)

 When I added the gautrain bus routes that I have actually travelled on,
I still used the official gautrain bus map as a reference: to correlate the
positioning and get the metadata (stop numbers, etc). Nobody can prove
which one I used more though - their map, or my on-the-ground observation.

 I wouldn't worry too much. Grant needs to worry more, now that he's

 We always come back to this, apologies, but it does seem a bit

 Nice work in the Midrand area, John! The Gautrain Bus Route is

 With regards to the order of the stops in the relation, I am afraid
iD (in-browser editor) is a little bit limited - the only way that I am
aware of, is to add the stops to the relation in chronological order - the
order seems to be maintained. To view the order of the items in the
relation, just open the relation for editing, and in the left-hand
toolbar, scroll down to where the members are listed - you will see all
members (in order).

 Otherwise, check out the JOSM editor for finer-grained editing tasks
like these.

 I'll happily call him. I guess OSM is looking for him to transfer it back as
 a donation, i.e. is not willing to pay?


I'd be willing to pay normal time and cost for the transfer, but not
ransom money.

 Grant, are you suggesting the domain is being held in a cyber squatting

The domain is used to catch openstreetmap typos. Many newbies
mistakenly believe the project called openstreetmapS

The openstreetmapS.com domain serves advertising and paid redirects.
Some with questionable content. Money is being made by exploiting our
project's name.

[talk-au] AU openstreetmapS.com domain squatter

[Grant Slater]

Hi OSM Australia,

Anyone up for this?

The openstreetmapS.com domain is being held by Michael Gilmour of
parklogic.com for sale. He is based in Camberwell, Victoria,
Australia.

The domain was originally registered on behalf of OpenStreetMap in
2007 but was accidentally not renewed.

Would any Australian OpenStreetMap member be willing to give him a
ring and discuss the project and transferring the domain back to the
project?

OpenStreetMap Foundation does have a trademark on the 'OpenStreetMap'
name to protect against such instances, but I'd prefer to try other
remedies before legal action.

Kind regards,
 Grant

Re: [OSM-Talk-ZA] Cadastral Information from Chief Surveyor

[Grant Slater]

Hi mtb,

They offer a complete set of high resolution sheets on 3x DVD. The set
is available at cost from their offices in Cape Town (and likely
others).
Unfortunately the sheets are not cropped and include the collar
(title, map key etc). I haven't yet tried to automate the copping.

I have a much older set of the sheets online here:
http://grant.dev.openstreetmap.org/cdsm-tiles-test/

I'm on IRC if you'd like to discuss further?

 Hi all,

 I came across this the other day:
 http://www.education.gov.za/EMIS/EMISDownloads/tabid/466/Default.aspx

 It is spatial data for all the schools in the country. I am not sure whether
 this can be used or not, but it might be useful nonetheless, especially for
 rural schools. I am not 100% sure what the guidelines on importing this sort
 of data are.

I informally asked the Department of Basic Education (DoBE) around a
year ago if OpenStreetMap may use the dataset. They said we may.
I have also been in contact with the DoBE employee who maintains the
dataset, he is eager for us to feed back updates/corrections.

The position data is unfortunately not reliably accurate for rural schools.

Gerhardus and I have a basic repo with some work in it:
https://github.com/gjngeldenhuis/osm-za-schools
The data can be loaded into QGIS (or similar), but converting the data
to OSM format would require work and coordination. (ogr2osm, buffer
excluding existing data etc)

[OSM-talk] Default OSM Tiles via HTTPS (Testing)

[Grant Slater]

Hi OSM Talk,

Approximately 20% of visitors to OpenStreetMap.org today will receive
the default tiles via HTTPS (ssl/tls).

This is to test HTTPS on our CDN infrastructure.

If anyone experiences any problems please can you report them in
channel #osm on http://irc.openstreetmap.org/

Technical:
We use a dedicated wildcard *.tile.openstreetmap.org certificate
signed by RapidSSL/GeoTrust on the 12 geo distributed cache servers.
The SSL termination is handled by nginx. SSL Report:
https://www.ssllabs.com/ssltest/analyze.html?d=a.tile.openstreetmap.org
Enabling SSL on tile is a step towards being able to offer HTTPS as an
option on openstreetmap.org for more than just the login page.

Kind regards,

 Hi everyone

 Warwickshire County Council have released 3 sets of aerial imagery under

Brian: Where did you get this information? I cannot find any public

I recommend that mappers DO NOT use the imagery until usage of the
imagery has been out-of-band confirmed as permissible for mappers.

 Thanks Grant,

 1) I really like the live map. I have been looking for a browser based map
 showing live buses!! I am sitting on the bus now and it is accurate
 including buses going in the opposite direction. Sometimes it is less good

 Slight glitch is that update times are exactly two hours fast when clicking
 on a bus. Pretty obvious what they should be so no problem.


I have improved the reliability and the timestamp bug:

I really must get my act together and finish the Bus countdown

I plan to launch the site publicly soon. Name suggestions appreciated.

 Exports the map as data. If the area is big, gives direct links to

 There was an option to download to PDF and PNG, which was nice so you could
 make a printed map immediately. Why has that been removed?


It hasn't been removed. It has moved to the more logical location of

As a sub-note: We have also had better hardware handling the those

Aerial imagery before major construction:
