 I don't see the point of distinguishing big edits because people don't

You've touched on something here that I've been thinking about. One
way of restating our goal in highlighting certain changes, either in
the overall history or in the changesets of an individual mapper, is:

It would be nice to see highlighted, or be able to filter based on,
changesets that are interesting to you.

If we can once define one or more definition of interesting it would
be possible to flag or filter accordingly. Some possible definitions
of interesting:

* Is within a certain radius of a certain location, very likely the
current user's set home location. To support this, a user profile
would allow setting of the radius of interest according to how much
that mapper gets around.

* Is within a certain radius (and this might be a fixed distance for
all mappers) of something the current mapper mapped.

* Is inside a certain bbox which the mapper would get to define in his
profile. A bit like the radius mentioned above, but maybe more useful.

In this context a big edit might still be interesting - but not if
it simply encompasses an area of interest. It would probably have to
include edits that were themselves inside the area of interest. That
seems hard, though.

Great! This is a tool I've wanted for quite a while. It seems to be
doing what it's supposed to, but with an interesting quirk that's
probably not a plugin issue at all, but rather one related to your
history web service.

Consider this node: http://www.openstreetmap.org/browse/node/256435531/history

Conveniently for test purposes, it is still at version 1, and the
creating mapper has (though only recently) accepted the CT. So given
that the status of data will be changing fairly swiftly, how long
should we expect it to take before the history service notices a new
acceptance?

I accept the spirit of the suggestion, but 1000 tiles is probably a
bit conservative. There is a level at which (IMHO) we would prefer low
volume applications of whatever sort to use OSM instead of Google etc.
even if that comes at the cost of tile accesses on OSM servers. I
suppose my rule of thumb would be that the human eyes looking at the
third-party application would be no greedier than had we had those
same eyes on the main OSM site.

In such cases, assuming correct attribution, such sites are providing
us with welcome publicity and we need not be mean with our tiles.

That depends very much on how you tell the users from this major new

 Steve was hinting at, would it?

To take that level of newbies and point them at today's toolset might
indeed require a lot of scale, though I admit I was more concerned
about the social effects. As such, defining a simpler, less dangerous
workflow for such users helps to buffer the database - both from
sheer load and from potentially bad data.

We are already overdue such a process, TBH. Whereas we have some
pretty good tools, like the Mapzen POI collector, there isn't a
comprehensive process of the sort that would, for instance, help avoid
the use of a POI collector to upload yet another copy of the same
hotel.

Indeed, when I read your post, Frederik, I suddenly got a shock. You
do have a point, but if we follow your reasoning through to its
conclusion we should already be discouraging (most kinds of) newbies
from joining OSM, simply because we don't have the (social)
infrastructure to sustain them without damage to the map. Many of us
have observed the phenomenon in our own communities - a new mapper
arrives on the scene, craps all over the map and vanishes. You always
used to get an element of this. As time goes by we get more and more.
And that, as you would probably be the first to point out, is fine,
the Community can cope, and that's why we have to be cautious in our
growth rate.

I would counter that this is insufficiently ambitious. I'm not talking
here about gung-ho ambition to have the most impressive graph of
contributors. Simply that if you can't carry the water to the fire as
fast as the tap can dispense it then there are alternatives to closing
the tap a little. You could get a bigger buckets. Or more buckets and
some pals to help.

Or maybe get a hose.

I don't know yet what our hose would look like. But if we have empty
or broken bits on the map... And if we have the option of getting more
people to work on them... And if we find ourselves tempted to turn
them away or to stall them a bit... Then we would surely be better
served by diverting some effort to finding ways of boosting our social
scale instead.

Re: [OSM-dev] Whitespace in tag-keys

2009-09-13 Thread Dermot McNally
2009/9/13 Martin Lesser ml-osm-...@bettercom.de:
 I did not find explicit informations about this issue in the wiki so I'm
 wondering whether whitespace in keys is a should not or a must not.

I think you're in fact addressing two separate issues here. As we can
see, the API will allow you to place whitespace in keys, but IMO this
is certainly a should-not case. Doing so, particularly as leading or
trailing space as in many of your examples, just confuses people.

But onto your examples:

 What's the recommended action if one detects tags like eg.

  http://www.openstreetmap.org/browse/node/275671906 (k=is in)
  http://www.openstreetmap.org/browse/node/447654517 (k= type)
  http://www.openstreetmap.org/browse/way/38170057 (k=   v=residential)
  http://www.openstreetmap.org/browse/way/39240565 (k= v=Gweyn Hughs Road)

These are just cases of broken data. Broken in the sense that all
clearly intend to record data of a kind for which very established
norms exist but that fail, presumably accidentally, to conform to
those norms. In a case like this, the data should be altered. Tools
like the JOSM validator already treat such cases as breakage and flag
them for the user.

These cases are comparable to typos (higway=primary) or failure to
stick to lower-case (Name=High Street). These too will yield
unexpected behaviour and should be fixed.

Re: [OSM-dev] Cloudmade routing for OSM rails_port site.

2009-04-29 Thread Dermot McNally
2009/4/29 Frederik Ramm frede...@remote.org:

 *If* our user base thinks that routing is a need they want met by the
 OpenStreetMap site, which is something that should be discussed.

There's another angle to consider here - we don't just need to cater
for our existing user-base (who are probably quite a resourceful
bunch). One of the reasons we have a site with a slippy map on it is
that it demonstrates to those unfamiliar to the project what
OpenStreetMap is capable of. That our slippy map closely resembles
those of Google, Yahoo and others helps to get around any scepticism
that might arise. This is why it is, IMHO, important that the map be
draggable rather than click-the-edge-to-pan-and-reload. AJAX-powered
maps are considered a baseline user requirement.

Clearly every potential user of OSM is different, but for me, a key
benefit when I discovered the project what hey, vector data, that can
be used for routing!. If we think that others discovering the project
would thing likewise then a prominent path from project home page to a
routing engine (and I really couldn't care less whose) would be a Good
Thing. As long as it works acceptably well, of course...

2009/4/29 Frederik Ramm frede...@remote.org:

 But isn't this angle one where the open/closed distinction gains weight
 again? Currently, you can (and I've done this a number of times) tell
 potential OSM users: Everything on openstreetmap.org is free software and
 free data - you can build the exact same site for yourself with all its
 functionality from our database and our svn *). With non-free routing or
 geocoding services that would stop.

Actually yes, I think I overstated my lack of caring where the routing
comes from - let me restate my priorities thus:

1. That we should have at least one routing engine to show that our
data will support that.

2. That we should have a selection of routing tools to demonstrate
that the data are engine-agnostic.

3. That a good proportion of the engines we show off be sufficiently
open to allow users to play with them or deploy them for their own
needs.

4. That our headline routing engine be open.

That is, whereas I have a preference for an open solution, so that
people get used to the idea that such problems can be solved using
open software, I personally wouldn't insist on it if (as I believe) we
are selling ourselves short without any on-site visibility of routing
tools.

However, I can understand that others would put my priority 4 right up
the top of the list.

2009/4/23 ce-test, qualified testing bv - Gert Gremmen g.grem...@cetest.nl:

 In JOSM however, we can ease the user in maintaining
 a self updating drop down box, and a number
 of standard comments with . behind it
 to stimulate completing.

 Updating highways ..  (user fills-in :)

 Updating highways = cycleways near Moskou

I've had some ideas along similar lines, though I see more automation
being used. Like Frederik, I think that comments are important -
important enough for us to strongly encourage mappers to use them and
appreciate their value. So I figure we should try to devise a
repeatable, automatable style of default commit message which would be
proposed to users prior to upload (in JOSM - Potlatch could silently
use it if desired) with an encouragement to adapt or replace it with
something better.

Possible formats:

Small|Medium|Large update within x km radius of lat/long
Update of x nodes, y ways, z relations within n km of town or city

Adding town or city names for better orientation makes it a lot
better, and would be feasible without external lookups in any cases
where the downloaded data set contained any place nodes of
significance.

What do people think? My intent here is that the automatic guessed
message would be as close as feasible to the kind of informative
message you'd like the user to learn to use.

(I'll duck any patches welcome answer right away by disclaiming all
Java skills, but hopefully somebody else will value the idea enough to
try coding it).

A little harsh :(

Lest I've been misunderstood... That you could retrofit such an
automated message is clear. For me, the value of computing it at
commit time is that it can be shown to the mapper as a default. The
intention being to trigger the following kinds of thoughts that he
would not think if faced with an empty text field:

* Oh, I can add a comment.
* Ah, so that's what comments are for.
* Ugh! That commit message is a bit crap. I'll replace it with a better one.
* No, my edits aren't centred on Mistfeld, I was actually mapping mole
tunnels, I should make that clear.

Now, if we think a default message wouldn't have this effect, then I
certainly don't think we should add one just for the sake of the

Re: [josm-dev] Trouble translating JOSM: Same strings used in different places

2009-02-21 Thread Dermot McNally
The issue of localisation frameworks is one that I've been considering
a lot in the last few weeks in my day job. Our application is built in
perl, and perl provides a more powerful, code-allowed tool called
maketext which does more or less what gettext does but with some extra
bells and whistles. There are ways to use the .po file format for a
maketext lexicon. Some background:

http://cpansearch.perl.org/src/AUTRIJUS/Locale-Maketext-Lexicon-0.62/docs/webl10n.html

But the one thing that surprised me is that all common lexicon
arrangements assume that strings should be keyed not by an abstract
key (like, say, EDIT_MENU_NAME, 'EDIT_TOOL_BUTTON_NAME) but by the
string itself in the primary language (Edit, with no option to have
a second Edit in a different context). This struck me as troublesome
during my investigations, partly because of the context difficulty
that we're seeing here, but mostly because for a string like ACME
Widgets company - your source of cheap widgets, any change, even one
of punctuation, or, in this example, a revision to your English
language slogan, forces an update of all localised string assets,
whether or not it's essential that they be adjusted (which for reasons
of English punctuation or grammar or single-market motto changes is
more trouble than is warranted).

Has this kind of problem not arisen many times before and been solved?

I've just looked at the piece of coastline in question and found two
errors in it (both now fixed):

* There was a duplicate node

* At a different place, the coastline overlapped itself.

I can see how these (particularly the overlap) could be confusing to
the DB. It may be worth trying it again with the new data.

2009/2/18 brendan barrett shogun...@gmail.com:
 Hi

 I've just signed up to the dev mailing list, and hopefully i'll catch
 up by reading the archives. For now though I have a question and
 please don't follow up with insults if you see the names Microsoft or
 SQL Server :P

 I'm trying to render coastlines in an application that I am building.
 The concept is simple: find the lines, and join them end on end until
 you get an area. Now my problem is with OGC standards. I'm using Sql
 Server 2008 *ducks for cover* and more specifically the new Sql Server
 Spatial types (Geography and Geometry). Sql Server 2008 seems to be
 pretty strict with OGC standards, and I am but a beginner when it
 comes to OGC standards.

 The problem i'm having is with some coastlines in OSM that double back
 on themselves. Like this one:

 This way http://www.openstreetmap.org/browse/way/13858554 doubles back
 on itself with this node
 http://www.openstreetmap.org/browse/node/130020792 having the same
 latitude as this consecutive node
 http://www.openstreetmap.org/browse/node/130020793.

 I think this is the reason for the way being invalid in Sql Server's
 eyes. The MS folks have included the MakeValid() function which
 corrects the way to comply with OGC standards, but this changes the
 latitude and longitude of every point in the line ever so slightly,
 and that's not desirable if you are matching ways end on end. I can
 use the Node Ids to match them, but the bigger issue is that my data
 is invalid and I can't use other spatial methods on it.

 I have 4 questions:
 1. Is this doubling back really an OGC restriction? It makes sense
 that these ways don't double back because it doesn't serve any purpose
 for a coastline (or for any line, you would expect even a path that
 doubles back to be at least some distance apart, or simply labeled two
 way).
 2. If this is a problem, is it something that will be fixed in the
 editors / the API?
 3. Is there anyone else here with experience with SQL Server 2008
 Spatial and OSM that might have some tips on dealing with all these
 ways?
 4. Does PostGIS have these types of issues?

 I'm thinking that the only way for me to deal with this is to correct
 the data in OSM (if it's clearly incorrect) or in my database once
 imported (if there's no other solution).

 Thoughts?

 Is correcting it inside OSM the only way to deal with this kind of

Well, I can't speak for SQL server, but this kind of data is something
we're usually prepared to call wrong for all kinds of other
purposes. It's certainly the kind of thing that has broken coastline
rendering in the past, caused flooding and suchlike. So fixing it is
The Right Thing.

 If so, i'm thinking of compiling a list of all the ways that do
 not comply, and then posting them somewhere so that we can all pick
 them off one by one. There are a lot in Australia alone (using the
 aussie export to get my testing done). I have a feeling that anyone
 using Sql Server Spatial will have these issues.

A noble idea. Automating it is the way to go. I cleaned the Irish
coast of defects like this by hand. It took quite a while and there's
somewhat less of it than there is in Oz...

2008-12-21 Thread Dermot McNally
2008/12/21 Dirk Stöcker openstreet...@dstoecker.de:

 a) I fixed the WMS displacement so it now again displaces the whole map and
 not a single image, but I did not get the display right. The
 visible/unvisible decision is still done based on the unmoved pics. (I can
 live with the fact that loading is done based on original position, but
 don't understand why the display is done likewise).

Nice to see us return to previous behaviour here.

 b) The plugin should use caching. Maybe we can turn it off for Yahoo or
 clear yahoo cache on each program start, but a normal download cache is
 required for the autoloading/autoremoval.

Can the webkit image not cache the tiles it downloads? If it could,
surely this is identical to how, say, Firefox or IE would cache
images, and if so, it should keep us within the terms of Yahoo's
conditions of use.

As an aside, has anybody managed to build the webkit image on MacOS?
I've come unstuck on one of the qt libraries, even though QT is
installed.

 To render the pages I am using gnome-web-photo application, which simply
 saves the png image of the website to file. The problem is, that this
 application is only for Linux. I need to find similar application for
 Windows, so if somebody knows about it, please write me.

From first appearances, it should run on more than Linux. It appears
to be available as a FreeBSD port and looks like it should run on any
other UNIX-like system. I'm having a go at building it on my Mac. It
your approach works, it will be a big improvement.

Re: [josm-dev] Validator

2008-08-20 Thread Dermot McNally
2008/8/20 Gervase Markham [EMAIL PROTECTED]:

 I think that both waterways and roads are layer 0, the ground, and
 when one crosses another, the upper one should have layer=1 - because
 there's air between it and the actual surface of the earth. I would
 apply this to any ground-based physical features, not just roads and rivers.

That articulates my view pretty well. Once again, consider that
layer isn't the same as level. We don't care whether a bridge
rises up above the level of the road either side of it. The
important thing is that at the point where it crosses the river, the
road must be on a higher layer than the river. So along the length
of a way, it is acceptable (and unavoidable) to have jumps in layer
that may not reflect actual changes in elevation. Layers exist to
determine the drawing order of overlapping elements, nothing more.

Re: [josm-dev] Bug 595 - Virtual nodes - Comments requested

2008-08-18 Thread Dermot McNally
2008/8/18 Petr Nejedly [EMAIL PROTECTED]:

 I just don't like the appearance of the virtual nodes. Could you turn them 
 into
 small (nonzoomed), thin red plus signs instead of rendering them the same 
 style
 as the way they sit on?

I love this new functionality, which as you say, is perfect for adding
detail to jagged ways. However, I agree with Petr. Having the plus
sign in the style of the way itself makes it look almost like the
direction arrows, where it should have a similar treatment to nodes
themselves.

I'll continue to use it in the meanwhile, though.

Thanks,
Dermot

Is anybody else having trouble with the slippy map chooser plugin?
I've just updated to josm-latest for the first time in about 2 weeks,

2008/8/16 Dirk Stöcker [EMAIL PROTECTED]:

 This information is shown in the ToolTip. You get this when waiting a
 short time over the error message.

Ah yes, so it is... It does force me to mouseover each violation,
though. For a large or detailed area, this is going to be very
impractical.

 Actually this is already implemented. It's only moved to the ToolTip for
 two reasons:

 a) There is so little space there in the Validator window

True - but to me, the existing top-level message isn't actually
useful, and could easily be replaced with the more specific message.
Furthermore, if I decide (as I am likely to) that it will be generally
acceptable for tertiary roads in my area not to have ref attributes, I
would value the ability to collapse and ignore a whole set of
violations. As it is, I'm going to have to search through a list of
acceptable violations to find the ones I really care about.

 b) When I change the generic error message, the valdition dialog will be
 filled with lots of different message types. This makes finding certain
 types more difficult.

Which types? As far as I can see, the only violations that will be
separated based on my suggestions are the ones that are already unlike
each other.

 Suggestions welcome.

I'd still favour my original suggestion - rather than group all of
these new errors under the single label they now occupy, group them
instead under their respective, detailed, labels. That keeps un-reffed
road errors away from, say, typoed landuse errors. But ultimately,
what I'm saying is lose the tool tip, at least for information like
this. A good rule of thumb here, would be that tool tips are good for
followup information that might not be necessary in all cases, or for
inexperienced users. But you shouldn't put data behind a tool-tip that
is necessary in order to make use of the error message.

 You can ignore them once and for all the time :-)

I haven't yet worked out the full scope of the ignore option - but it
doesn't seem to ignore all similar cases, only the specific object I
have selected. In any case, some violations are things that you care
about (like missing refs) but can't always do anything about. (like
tertiaries, where it can be difficult to determine the correct ref).

 Don't know how make an ignore for specific tests in the test-set. But it's
 a new feature. Give it some time to mature.

For sure. Lest there should be any doubt, I really like what you've
done here. I'm just struggling with aspects of how the results are
output.

 Yes. The other validation types. Think of e.g. 30 different TagChecker
 types and one unclosed way. You wont find it in this batch of TagChecker
 stuff.

I'm not sure I see what you mean here. It doesn't matter to the user
if a crossing way or unclosed area message isn't generated by the tag
checker, even if another 30 messages are. Each violation message
represents something that the mapper needs to review and either repair
or accept in its current state. Do we really need to contain the
tagchecker messages behind an overall label? Maybe there's a technical
reason, but it feels unnecessary from a UI perspective.

[josm-dev] Filled roundabouts

2008-07-14 Thread Dermot McNally
Hi folks,

While at SOTM I updated to the latest JOSM, to discover a new
feature. Roundabouts are now displayed with a dark green fill, but
(the important bit) _without_ the outline colour correctly reflecting
the classification given in the highway tag. Is this
intentional/considered useful or is it a side effect of another
change? I don't really mind the fill (in fact, it's a useful visual
clue that allows us to spot roundabouts not correctly tagged as such),
but losing the highway colour is a pain.

Cheers,
Dermot

 Unless someone objects I will upload the SWBD data for an area I am

That seems very reasonable. If subsequent mappers don't like the

Re: [OSM-dev] Lake data from SWBD

2008-05-10 Thread Dermot McNally
2008/5/10 Ludwig [EMAIL PROTECTED]:

 Is there a reason (other than nobody has done it) why the lake data in this
 data set has not loaded into OSM? Are there objections to this data being
 uploaded for lakes only?

I looked at this source for Ireland - mostly with rivers in mind, but
I did look at lakes also. What I found wasn't very impressive. Even
though Ireland is relatively full of lakes, it was easier to get good
results using the lakewalker script (and, more recently, plugin). For
small lakes, the inaccuracy of the data makes it unattractive. For the
larger ones there's not that much point, since a morning with
lakewalker will give you something that you have at least visually
verified against landsat.

2008/4/23 Lauri Hahne [EMAIL PROTECTED]:

 Isn't that what's Potlatch for.. (if we forget that P. is malum in se (or at
 least used to be))

Perhaps - but consider the two biggest points of agreement between all
on the Great Potlatch Debate:

1. It offers the most immediate way to update the map data
2. It offers the easiest way for newbies to make a mess.

There are people who would be very able and willing to enter missing
street names and correct typos, but who would not have the editing
skills to avoid moving nodes around by mistake. A higher-level tool
that exposes only the most important meta-data is very useful. In
fact, I'd imagine it shouldn't even allow just any meta-data changes,
at least by default. I'm thinking more of a tool that allows users to
edit specific fixed attribute values:

name
name:xx
ref
int_ref
(other refs)
place (maybe, but if so, constrain values to the valid ones)
oneway (likewise - I saw a street yesterday with something like
oneway=yes (south and west))

My instinct is _not_ to expose even highway, but no doubt others
will disagree.

One last point - there's no reason that Potlatch couldn't do all these
things using a dedicated move-nothing mode, it certainly offers a
lot of opportunities to reuse the preset selectors.

One drawback of starting it like that is that you don't get to boost

It was one of the suggestions at the time. Some folks had concerns
