Editing PostGIS/GeoServer data via web?

Question

I've got PostGIS installed and would like to create a web application to do some simple edits:

• Draw manually (over a Basemap) points, lines and polylines, using snapping points (points, end of lines, intersections, center of circles)

• Delete points, lines and polylines

• Rotate a line or group of lines around a point

• Move a line or group of lines with a base point

• Move polylines and points (manually and to a point given by the coordinates)

• Edit position of vertices of polylines and lines (manually and to a point given by the coordinates)

• Create buffers around points, lines and polylines

Which is the best way to do this via web? Is there any already-built JavaScript library?

Answer 1

You should use Geoserver WFS-T,WPS protocols and some client software like openlayers http://openlayers.org/dev/examples/wfs-protocol-transactions.html

Answer 2

I would look into Cartaro, it appears to be based off of OpenLayers Editor by geOps.

I also just saw this OpenLayers WFS-T Using a GeoServer Hosted PostGIS Layer.

Answer 3

I do not think there are any "ready-to-use" libraries that covers all your needs, but with the mentioned combination of Geoserver (with wfs-t) and OpenLayers it should be possible to create what you want. Maybe mapfish has some more convenience-methods?

And, if web-based is not a "must have", then consider using Quantum GIS.
