Hi, I'm collecting some ideas on the ideal setup for a collaborative editing interface in QGIS. Our current setup is that we have several field offices that collect and update vector data. I installed a geoserver instance with postgis and we can now serve data from a central server to the field offices (whenever online). What we are looking for is way to be able to: 1. Download subset of the data and bring it on field. 2. Allow field workers to update the offline data. 3. Back to the office, synch the data into the main server.
There are several approach to server-based editing all within QGIS. The list are: 1. Offline editing via spatialite. - This allows conversion of the postgis data into an offline spatialite db which can be used in the field. But no functionality to merge the edits back into the main postgis db. 2. Direct WFS-T connect and edits - straightforward "Toggle editing". But requires server connection during edits and no change/commit monitoring. 3. PG-version plugin that allows editing, commenting edits and to rollback. - the best approach so far but same with WFS-T, need continuous connection to the server. Is there a way for a hybrid approach wherein we: 1. Download a subset of the data as a spatialite db. 2. Do offline edits. 3. Merge the changes to the postgis db (either via wfs or direct postgis connect) with some verisoing functionality. What we are looking for is a QGIS-way of doing this since QGIS has very good editing tools already compared to an Openlayers/GeoExt route. Another approach is welcome. -- cheers, maning ------------------------------------------------------ "Freedom is still the most radical idea of all" -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ ------------------------------------------------------ _______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
