Three Cases for Using the ArcGISServer Out-of-the-Box Technology
•Small Government Enterprise Licensing Agreement (ELA)•Server Enterprise – Advanced 9.3.1 and 10.0
•Needed quick distribution of specific GIS data and tools.
•Minimal GIS staff time available.
•All applications created using the ESRI ArcGIS Server ‘out-of-the-box’ technology.
BACKGROUND
OVERVIEW
•Three of Goodhue County’s GIS web applications:•DFIRM app - Static Data •Historic Places app - Data Periodically Updated •Dispatch app - Data Constantly Updated
•Each site created differently depending on its use.
•Each works well for what is needed.
DFIRM Web Application
DFIRM WEB APPLICATION
Purpose: •Inform land owners of changes in FEMA DFIRM maps.

LIVE DEMO
PROS/CONS
Pros:•Fast Setup.•No programming needed.•EASY editing capabilities for non-GIS users.
Cons:•Would like user-friendly ‘zoom-to-feature’ option.•Would like ability to draw lines or polygons ‘free hand’.•Current site does not have secure access.
SUMMARY
•Three different web applications created using OOTB.
•Different caching options work well depending on the individual project and the purpose of the application.
•Has worked well for our needs.•Fast to setup and make tools/data available.•Can go back later to customize or improve.
WHAT’S NEXT?
•Recently upgraded to ESRI ArcGIS Server 10.0.
•Apply higher security to Dispatch applications.
•Recreate the Historic Places web application to use separate cached services.
•Crime mapping web application – public and internal.
