Evolution of Computer Cartography
17
What is Computer Cartography?

• Computer Cartography the science, technology
  and art of making maps using computers and other
  new technologies

18
What have computers done to Cartography? -
Faster and Easier, even Cheaper

• Computer graphics for map drawing
• New survey technologies for map update

• Computer data transfer via mobile storages and
  networks for map sharing
• Computer printing technology for map production

19
What have computers done to Cartography? - More
Accurate and More Precise

• New survey technologies increase the accuracy of
  geographic information

• Computer graphics and plotting/printing vs.
  manual drawing
• Computers enable more significant digits more
  precise

What have computers done to Cartography? - The
Design Loop!!

23
What have computers done to Cartography? - The
birth of Analytical Cartography GIS

• Born in the 1960s and 1970s
• From technological focus to theoretical focus

• The early Geographic Information Systems are more
  like computer mapping programs plus a few data
  management functions.

24
What is Analytical Cartography?

• Waldo Tobler (1966) solving cartographic
  problems

• Waldo Tobler (1976) mathematical and
  analytical parts of cartography that remain
  independent of technology that applies to both
  real and virtual maps (Moellering, et. al.
  UCGIS)

25
Typical Topics in Analytical Cartography

• Map Transformation
• Sampling
• Critical Features
• Map Generalization
• Shape Analysis
• Data Models and Structures
• Analytical Visualization
• A lot more
