Hi Pierre,<br><br>As far as XAPI servers go I have given up for now, although MapQuest is running a more reliable instance[1] that may be useful, although they employ Ian's Java implementation as well so the same bbox limitations likely apply.<br>
<br>I am, in fact, working on a similar project in the Netherlands and for an up-to-date data feed for CCTV cameras I use the process described here[2]. I'd love to compare that to your approach, we can probably benefit from each other's work. <br>

Hi, i'm a french contributor and i look for advice for a project.<br>
<br>
I'm processing free french city official data (from insee, official stat<br>
agency) and i have to match those city with osm city (place=*) to<br>
geolocalize it on a map.<br>
The project is to present cctv surveillance in the country (see demo at<br>
[1]).<br>
<br>
To get those data and preprocess them i used XAPI to retrive all nodes<br>
with tag place=* :<br>
<br>
The result is fine but XAPI servers are randomly running and data seems<br>
old. New Java XAPI servers do not accept the bounding box : too large.<br>
<br>
What are the best way to retrieve OSM raw data (xml format would be<br>
preferable) to update regulary the project's data ?<br>
<br>
Thanks.<br>

<br>
These map show city global data (user contributions) and individual cctv<br>
camera localisation (from OSM man_made=surveillance) when you zoom to a<br>
city with cctv mapped (ie. Strasbourg) :<br>
