href="http://wiki.openstreetmap.org/wiki/Osmfilter"></a> Hi all,<br>
I already replied Pierre-Alain on the french list, but it maybe
useful for others too.<br>
For an extract of cross-country trails at [1], I use a world planet
file updated by osmosis as a file with daily diffs whenever I feel
like too. Find the script attached.<br>
Then Osmfilter [2] do the filtering, as in my case Osmosis is not
able to filter relations recursively enough.<br>
Planet update is ~4 hours, filtering ~2hours on a 4Go ram machine.<br>
By the way, same result on a 7200rpm disk or SSD disk. I guess ram
and compression are the bottlenecks.<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>

Best<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>
