GIS Overview
• GIS (Geographic Information Systems)
  • GIS integrates information spatially
  • GIS is a decision support tool
  • Changes the way people see information
  • Data, Data, Data!!!
• GIS provides benefits in:
  • Revenue enhancement and cost savings
  • Improved business processes
  • Improved safety
  • Analysis & Planning
  • Communication
GIS Overview
• GIS has gained even more public attention and traction
   • Google Earth & Maps
   • Yahoo Maps

2002 GIS Assessment Study
• CIO “Countywide GIS Assessment Study” –
  January 2002.
   • Departments have different levels of GIS
     expertise (“haves” and “have-nots”).
   • Users don’t know where to access data and
     GIS expertise.
   • Duplication of effort increases cost.
   • Departments see the potential of GIS, but
     don’t know where to start.
• Enterprise GIS can extend the benefits of GIS
  to the entire county.
GIS Assessment Study

•    Section 4 – Three Enterprise GIS
     Implementation Options

   • Help transfer GIS expertise from “have” to
     “have-not” departments.
   • Reduce implementation costs
• Develop County of Los Angeles Enterprise GIS
