<div>Jo, I'm not sure that the GRB layer should be part of the
default layer set. It becomes too dangerous people will use
it without reading about the limitations.<br>
<br>
</div>
But anyway, thanks for working on it.<br>
<br>

<div>Otoh, supporting iD is also important. We can't say "Don't
trace from Bing" if people can't use Agiv in iD. For that, we
would need a TMS. So that either means setting up a map proxy
to convert WMS from Agiv to TMS, or finding some TMS layer
available (there are TMS layers for older imagery from Agiv,
but I've found none for the most recent imagery). Then, it
needs to be added to this repo: <a moz-do-not-send="true"
href="https://github.com/osmlab/editor-imagery-index">https://github.com/osmlab/editor-imagery-index</a><br>
But I'm not experienced enough with imagery to accomplish
this.<br>
<br>
Jo, are you, or is there anyone else wanting to look at this?
I think it would save us a lot of problems.<br>

The <a href="http://www.papou.byethost9.com/maps/mapproxy/">Mapproxy
I built and published</a> for you all contains a configuration
example to convert OSM TMS to WMS and serve it. Mapproxy can
equally well convert TMS from WMS. I made it in particular to help
an Agiv conversion but I never heard about that Agiv issue any more.<br>
<br>
I have asked twice if an Ubuntu or Debian host connected to IP would
be available to run support programs. There wasn't any sort of reply
so I completely abandoned the idea.<br>
<br>
The best idea would be to use JOSM if the SPW were spending a few
hours to serve WMS 4326.<br>
Failing that or/and if JOSM seems too difficult to use, Merkaartor
is a possible alternative that some people like on a PC. Last time
I tried it, I saw a prohibitive map distortion on the screen when
using Lambert projection and I prefer correctness and features to a
nice look.<br>
<br>

<div>This is long overdue, but I finally got
round to it. I added a page<br>
<br>
<a moz-do-not-send="true"
href="https://josm.openstreetmap.de/wiki/Maps/Belgium"
target="_blank">https://josm.openstreetmap.de/wiki/Maps/Belgium</a><br>
<br>
with WMS sources for Belgium, for which we
have permission to use.<br>
<br>
So now there are 3 more entries on this page:<br>

The resolutions are all better than Bing. They
are also more recent.<br>
<br>
</div>
Is there somebody who knows a convenient way to
add those coordinates, so a shape is shown?<br>
<br>
AGIV also has coverage for Brussels, The Walloon
imagery also covers the German speaking part of
Belgium.<br>

<div>I don't know much about projections, but
EPSG:4326 seems to work just fine for all three.<br>
</div>
</div>

</span> Projections are simple: a mathematical
transformation of the Earth surface to draw it on a plane
(screen).<br>
EPSG:4326 uses the GPS coordinates (degrees) linearly (d °
NS/EW = c cm vertically/horizontally).<br>
Cylindrical is the projection as if by light beams
perpendicular to the Earth axis.<br>
Mercator is the same but with a vertical correction so
that the polar regions are not flattened.<br>
These 3 are quickly transformed one to another with little
CPU.<br>
Hence, JOSM, which normally uses Mercator on screen, can
convert any to its screen projection.<br>
<br>
The (Belgian) cartographers use Lambert projections which
is similar to cylindrical, but on a cone that is tangent
to a line going across their country (Belgium). This is
so that the proportions of the distances are the same
vertically and horizontally. The Belgian servers serve
them too. In addition to EPSG:4326. Except SPW (<span><span>
;-) </span></span>).<span class=""><br>

</span> I would add Wallonia 2009. It is sometimes useful
(e.g. to get rid of trees).<br>
Is it just a matter of editing the file? Have to refresh
the server?<br>
Can id=SPW be the same or what should be used?<br>
<br>
What is that (3.xxxxxx) after the name JOSM displays? Any
way to get rid of it?<br>
<br>
