I'm getting this error on a recent master if I try to download data in a
non-geographic projection:
=============
Download failed.
Error downloading
http://overpass-api.de/api/interpreter?data=(node(-2.96917e+06,3.14947e+06,-2.96473e+06,3.15641e+06);%3C;);out;
- server replied: Bad Request
=============
Might be good to check the projection and give a more useful message if
it's not geographic (or translate coordinates before download).
Regards,
Rudi

so finally I have pushed my initial work on OpenStreetMap integration<br>
to master... d'oh I have missed The Open Data Day (Feb 23) by few<br>
days! The idea is to completely replace the current OpenStreetMap<br>
provider and plugin. As announced in the list before, the new OSM<br>
support is read-only and right now I have no plans to add editing<br>
functionality. Editing would mean a _lot_ of work - map tools,<br>
tracking of changes, conflict resolution - and there are already great<br>

<br>
If you would like to test the new stuff, go to menu Vector ><br>
OpenStreetMap. No need to enable any plugins. The workflow should be:<br>
0. get OSM XML file (from web or download in GUI)<br>
1. import XML file to a SQLite topology database (once)<br>
2. export SpatiaLite layers from topology with a fixed set of tags - attributes<br>
<br>
Integrated download uses Overpass API, so you should be able to<br>
download data from any extent size. The download server in GUI is<br>
currently fixed to <a href="http://overpass-api.de" \
target="_blank">overpass-api.de</a>. When using download, make sure to<br> set high \
timeout (Options > Network > Timeout for network requests) -<br> currently \
there's a problem with QGIS network manager - it will time<br> out after the \
fixed time even if the data is being continuously<br> received.<br>
<br>
The work is by no means complete, there are various pieces missing,<br>
though it should be already usable. Some features I would like to add:<br>
- advanced download queries (e.g. filtering by tags)<br>
- filtering on export (e.g. export only railroads, only restaurants)<br>
- python bindings<br>
- support for relations<br>
- identification GUI (e.g. see all tags, even those not exported)<br>
<br>
There is a low-level API in qgis analysis library which should allow<br>
3rd party tools/plugins do some work with OSM data (currently<br>
QgsOSMDownload, QgsOSMXmlImport and QgsOSMDatabase classes).<br>
<br>
Please let me know what do you think about it or if you encounter any bugs.<br>
<br>
I will be removing the OSM provider+plugin very soon. This is another<br>
piece from the master plan for removal of old symbology (OSM provider<br>
implements a renderer based on old symbology).<br>
