I manage a GIS at a small company in Tempe, AZ. We’ve been designing web based GIS sites since the old ArcView IMS extension. We’ve moved from MapObjects IMS to ArcIMS 3,4,9 and now we’ve begun to look at UMN Mapserver. Basically we’ve heard from clients that they are having problems with the cost of maintenance of ESRI products. If we could eliminate ArcIMS/ArcSDE for these people and still provide our look and feel, this might be a market worth looking into. I’d love to make our sites work with any backend that the client wants. We’ve used .NET in our latest products, but maybe PHP or JSP would be a better choice for doing this. I’m just not sure what to think at this point, but I’ve got our database programmer looking at getting PostGIS and Mapserver installed on our Linux server.

It’s going to be quite a move from ArcIMS/ArcSDE/Oracle, but maybe we’ll learn something. I’ll post more about this next week when we get it installed.
