Title: History%20of%20GIS


1
History of GIS
2
Base Maps
  • 1600s linking mathematics and analytic geometry
    to create coordinate system

3
Use of Overlays
  • Maps of the Battle of Yorktown contained hinged
    overlays to show troop movements
  • Mid-19th century Atlas to Accompany the 2nd
    report of the Irish Railway Commissioners showed
    popn, traffic flow, geology and topography on
    same base map

4
Dot Maps
  • 1855 use of dot map to display epidemiological
    data, leads to discovery of the source of a
    cholera epidemic in England

5
The Five Phases of Development
  • The Research Frontier
  • Experimentation and Practice
  • Commercial Phase
  • User-Dominance
  • Web-Based Internet GI-Science

6
The Research FrontierLate 1950s to Mid 1970s
  • Individual Led Development
  • 1958 - NASA - Data Availability
  • 1963 Canada Geographic Information System
    created to anyalze data collect by the Canada
    Land Inventory
  • 1968 - Apollo 8 - Returned 1st Images from Space
  • Lack of Computing Resources
  • 1960s - Early computer mapping packages
  • Harvard - SYMAP, IMGRID, CALFORM
  • Isoline Maps
  • 1969 - Jack Dangermond began ESRI
  • Arc Info

7
Experimentation and PracticeMid 1970 s to Early
1980s
  • National Agencies Driving Development
  • Government Funded Research
  • NOAA Established
  • NASA
  • Huge Data Increase
  • SPOT, LandSat
  • Role of the Individual Diminished

8
Commercial PhaseMid 1980s
  • Corporate Software available
  • Competition
  • PCs becoming popular
  • Individual market opening up
  • Isolated systems running GIS isolated data sets
  • Minimal sharing of data
  • GPS becomes fully operational

9
User Dominance1990s
  • Strong competition among software vendors
  • Databases began to become distributed
  • Internet becomes operational
  • Network accessibility more common
  • Development of Standards
  • Quality control
  • Data tracking (Metadata)

10
Web-Based Internet GI Services ShiftLate 1990s
- Present
  • Distributed and Interoperational Architecture
  • Data resides and is distributed over a network
  • Limitations - Requires high speed and wide
    bandwidth (Network Capacity)
  • Standardized Data
  • Data is not platform or program dependent
  • Google Earth, ArcWeb Explorer, National Map
