GEOG 479
Cyber-Geography in Geospatial Intelligence

Summary and Final Tasks



TFL states: "Everything is related to everything else, but near things are more related than distant things."

In 1999 he followed this up with: "The phenomenon external to an area of interest affects what goes on inside. This may end up becoming the Second Law of geography" - TSL.

Tobler's "first law of geography" has been an important part of geography ever since 1970. Recently, it has become even more popular and important in GIScience. GIS did not exist when this was first stated, but it is now recognized as a fundamental concept in spatial statistics, but also in geography in general. It forms the basis for spatial auto-correlation and geo-statistics.

Tobler qualifies his ideas with: "The model(s) recognize that people die, are born and migrate (what) but it doesn't explain why people die, are born and migrate." This difference between "what" and "why" will re-emerge in coming weeks.
