I have gotten quite involved with GIS lately and just wanted to ping the lists to see if there was any interest out there.
I have been writing an WFS server interface for OFBiz and a GeoRSS service. The WFS server will allow you to use open source software, such as MapBuilder, to overlay points of interest icons on top of base GIS layers such as ones that you get from Google, Yahoo or Microsoft (or build up on your own). GeoRSS allows you to use Google, Yahoo or Microsoft's api to overlay a poi icon on their maps. There is a nice java-based GIS server, Geoserver, that runs nicely as a webapp next to OFBiz apps. In my mind, GIS is sort of like Content Management - it will become a bigger part of websites in the future. -Al
