I'm researching for a project that will probably use Zope. For this project we will require a simple GIS component for display and information retrieval. I've noted three possible products so far and I'm wondering if anyone has any experience with these products or with others. My interest is what worked well, what didn't and how difficult were they to use with Zope. The products I've identified as potentially useful are: MapIt, MapServer and OpenEV. So far the MapServer seems to be the most likely candidate for our use. Thanks in advance. Here is one one other that I know of that may be of interest. BBN Technologies; contribution to the OpenGIS effort, a product called openmap, www.openmap.org. This is a JavaBeans tooolkit. I have downloaded it but have not done anything serious with it.
