Hi, have a look at mapbender and its digitizing capabilities: http://www.mapbender.org/ http://www.mapbender.org/index.php/Digitalisierung#ENGLISH
Try the link to the digitizing gui. Digitizing functionality includes e.g. snapping to nodes and saving geometries via wfs-t (geoserver->postgres). Cheers, Michael 2007/1/7, Mike Conlow <[EMAIL PROTECTED]>:
Hi: Does anyone know of a good applet or utility to allow clients to draw polygons on a map and feed them to PostGIS? The issue I am trying to deal with: I have a lot of points and I need to let a client draw a polygon around a subset of those points and tag them with their name or a code or something. I think the easiest way is to pass the polygon to PostGIS...but if there are other ways that I haven't thought of...
