• Analysis tools can be very powerful.
- Configuration by an GIS Analyst
- User just needs to click a button
- …everything else is “under the hood”
Future Plans

implement more web based maps,
host a map gallery, and develop more
tools for our internal and external
customers.
• We are looking now at a governance
model for our Enterprise GIS, as we
socialize the capability within the
organization.
