What Weve Learned Early client feedback paid off downloads integration with other efforts Example of what can be accomplished once a server-based GIS infrastructure is in place Web services saved a lot of time on basics Decision-making processes are often fuzzy and we need map processes that accommodate this ArcGIS Server has been a powerful platform on which to develop some sophisticated functionality

Next Steps Demographic/Segmentation Reporting – (Business Analyst Online) Public web deployment Integration with commercial real estate listings service Encapsulation of basic process into a web service for integration into departmental applications – school siting
