What We’ve 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
