  • Introduction
  • Why the need?
  • Alternatives
  • Our Solution
  • Challenges
  • Application Functionality
introduction
Introduction
  • ISA serves 16 Agencies, 5 Departments
  • Approximately 500 ArcView 3.x licenses
  • Upgraded to 175 ArcView 8.x licenses
  • Further refined to 31 single use and 48 floating licenses as IDV was developed
  • A large majority are casual users who:
    • View data
    • Add local data
    • Print
    • Find addresses
    • Save projects
why the need
Why the Need?
  • License maintenance costs
  • For a majority of our users, ArcView was too robust.
  • What are the alternatives to ArcView (2003)?
our initial solution
Our Initial Solution
  • Initial solution was to use ArcIMS Java Custom Viewer
  • Limitations encountered during development
    • Very limited object model
    • Not very flexible
    • Is based on MapObjects Java 1.0
    • Limitations in selection capabilities.
    • Couldn’t view attribute table
    • No printing capabilities
our second try
Our Second Try
  • Discovered that ArcIMS Custom Java Viewer applets were built on MapObjects Java…therefore we decided to build our own applets on MapObjects Java
  • Switched to MapObjects Java 2.0+
    • Access to more base objects
    • Much more flexibility
challenges
Challenges
  • Silent installation – 3 different vendors to work with (ESRI, Sun, Microsoft)
  • Rewriting/reinventing the wheel
  • Encountering intrinsic bugs due to the scale of this project
benefits
Benefits
  • Reduce license costs!!!
  • No desktop installations
  • All installations are silent behind the scenes over the Intranet
  • All ArcIMS Java Custom Viewer limitations were overcome
  • The wheel is now our own wheel to fix and extend
