NOTES:

  • What is GIS?
    • aka Geographical Information System
    • A system that merges geographical information in a computer database with spatial coordinates on a digital map.
  • Types of useful information stored in GIS
    • Natural things
    • Man-made things
    • Tracks, speeds, projections
  • Major applications of GIS
    • Geographical mapping
    • Tree and animal locations
    • Documenting environmental changes (stream bed movement, beach erosion)
    • Addressing systems speed and projection capability
    • Emergency service instructions
    • Airplane movement and location (Ron Brown)
  • Ramifications
    • Scientific (gypsy moth)
    • Business (manage assets, track goods)
    • Life
    • Municipalities (fire, ambulance, police)
    • Ethical issues
    • Military applications
    • Power grids
    • Managament of traffic signals
