Document Summary
Gg102 class 2 the geographers toolbox: maps. Street, buildings, vegetation data integrated data (data layers) Eg. plow routes; noise exposure; customer base; harass map. Giant storehouse of reference info to a particular location. Device connects to at least 3 overhead satellites and can calculate your location. Simplifies reality so we can comprehend reality better, faster, more thoroughly. Standards/conventions (blue means water), selective about info (level of detail), generalize some info.
