<div class="moz-cite-prefix">Hi Mike,<br>
<br>
Thank you for organizing a mapathon.<br>
<br>
The images were originally from WMS servers at Instituto
Geográfico Militar (IGM) or Sistema Nacional de Información y
Gestión de Tierras Rurales (SigTierras).<br>
<br>
TMS layers were setup as proxy cache on OSM France server, and,
even with that, a WMS server became overloaded at the beginning of
work on a new area, and became slow to answer, before the tile
cache could fill and then provide the tiles to subsequent requests
without having to get them from the WMS server.<br>
<br>
At some point yesterday, there were more than 177 mappers active
at the same time on a TM project, with hundreds of tiles being
requested and served each second. <br>
<br>
What you described about the maximum zoom level sounds like an
issue that was reported, depending the maximum zoom level
available from a WMS on a given image. For that image, setting the
max zoom level at 18 ("tms[18]:" at the beginning of JOSM URL)
solved the problem.<br>
<br>
In general, what can be useful to solve such issues is to send a
screen capture and the coordinates where it is captured to the
person who created the project (and also to me if the imagery is
hosted on openstreetmap.fr server).<br>
<br>
Best regards,<br>
<br>
Jean-Guilhem<br>

<div>This was not our experience. Below a certain zoom level
it would load at all. </div>

<div>In the past the way I have seen it done is each
neighborhood / subdivision gets its own landuse =
residential closed way. Granted that without local
knowledge, it is difficult to tell. In any event, I agree
that more explicit instructions are needed.</div>
