Re: [OSM-dev] Odd data in daily diffs (potlatch related?)

Actually I'd like to garnish my important notes with a ^G every now
and then. Since we now have excellent audio support in JOSM, I figure
it should be possible ;-)

Wow. Right. I looked up the XML definition and got:
http://www.w3.org/TR/REC-xml/#charsets
In particular:

Char	   ::=   	#x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] |
[#x10000-#x10FFFF]

So *any* character <32 that's not a tab, newline or linefeed is
illegal in XML, not matter how you encode it. Since we have decided
that XML is the standard format for transport of OSM data, this means
we must ban those character now and forever in all layers and complain
loudly to any program generating such characters...

So brett, looks like you were doing the right thing after all, but the
failure mode could have been clearer.

Have a nice day,

Re: [OSM-dev] SoC project idea: Wikifikation of OSM

Hi,

just wanted to let you guys know that I decided to not apply for SoC. I
think I would have been up to the challenge of the project but the
discussion here showed me that I maybe had a bit a wrong idea of the
scope, especially with looking at features and databases at the same time.
Also, more importantly, I desperately need money and 5000 bucks for the
entire summer won't get me very far. Thanks for your feedback on my idea
anyways! And obviously I will make some smaller contribution to OSM anyway
once I have more time on my hands.

[OSM-dev] svn Account

Hi,

A coworker of mine and I implemented some osmarender rules for the
piste map proposal
(http://wiki.openstreetmap.org/index.php/Proposed_features/Piste_Maps).
We would like to add them to the render.

Is it possible to get an svn account that for?

Username: studerap

Best Regards,
Raphael

[OSM-dev] Potlatch backgrounds on Ubuntu

I've had a report from a user saying that he can't access any Potlatch  
background imagery (Yahoo, OAM or whatever) on Ubuntu 7.10, Firefox  
2.0.0.13, Flash 9.0.115.0.

Anyone else have any experience with this?

cheers
Richard

Re: [OSM-dev] Potlatch backgrounds on Ubuntu

It appears to be working fine on the one of my laptops (Ubuntu 7.10 and FF
2.0.0.12. I didn't check the Flash version).

Cheers

I use Ubuntu for Potlatch development, and I can tell you it works
with Firefox 2.0.0.13 and Flash 9.0.48.0. That's apparently the last
flash version available on the ubuntu updates server.

Thanks both - much appreciated.

GML 2.x are mostly user in practice. These versions are less complex as the current version GML 3.2.1.
And in fact, ESRI for example only supports a sort of "ESRI Profile" for GML.
So I would prefer version 2.1 of GML if I had to decide.

But that would then be some "custom addition" that's not enshrined in
GML, wouldn't it? I mean I could do all sorts of things with GML based
on the fact that it's XML, but an application that claims to be able
to "read GML" would not necessarily be able to read whatever extra
stuff I built in.

What, exactly, does it mean if a product claims to "support GML"? Is
that a more or less bogus claim like "this product supports CSV" or
"supports ASCII"? Or is the information that something supports GML a
hard fact that tells me it will be able to read and meaningfully
process my file if it has the proper structure?

As far as I see, GML is based on "profiles" which seem to define a lot
of what's in the file. Could I simply define an "OSM profile", export
GML using that profile and tell everybody that I now support GML?
Would applications that claim to support GML be able to read my data,
given a proper definition of the profile - or is GML support in
applications usually limited to the "Simple Features" profile?

I have the impression that this depends on what people want to do with
the data. It seems to me that topology is very important if you want
to *edit* the data, especially if it has some kind of network
structure. As long as you only process read-only data, a lack of
topology doesn't hurt you too much.

I could well imagine downloading map data from somewhere and
instructing my GIS program to filter and display all that in a nice
way without topology. But downloading, modifying, and uploading again
seems difficult. On the other hand, distributed editing is not a
traditional GIS core task, so maybe those systems that did support
topology were perceived to add too much complexity for too little
value.

I'm with you in that it would have a certain appeal to have a few
extra basic types in our repertoire, instead of just nodes and ways.
We did have an extra area type once, but that was never used and so
vanished again.

On the other hand, we only have to store what our mappers map, and
there are certain limits to their creativity when it comes to
designing complex computational geometry artifacts. They're not
professionals and it is difficult to force complex models on them.

Bye
Frederik

Is he running a amd64 distribution in a 64-bit machine? Is he using 
nspluginwrapper by any chance?

Just for the record: I'm running Debian amd64 unstable/experimental, firefox 
(iceweasel) 2.0.0.13, nspluginwrapper 0.9.91 and flash 9.0 r119. Potlach 
works pretty fine.
