<br>
thanks for the feedback.<br>
<br>
Sure, having an asynchronous process to generate datasets for download<br>
user requests is something we have been talking since a while.<br>
In my opinion this process shouldn't be tied to GeoServer, but should<br>
be Pythonic, in the form of tasks in Celery for example. And of<br>
course, using ogr2ogr and gdal_translate<br>
<br>
This way code will work even when once it will be possible to use<br>
GeoNode with different map servers (for example with the QGIS Server<br>
one).<br>
<br>
Obviously if you guys have something already working as a GeoServer<br>
WPS, it would be very welcome in the meanwhile!<br>
<br>
thanks again<br>
