3. Geographic Information Systems (GIS) Geography – The study of where features are located on the Earth’s surface. Geographic coordinate systems latitudelongitude - Represent exact positions on the Earth - 42.3216, -71.089118 (lat. long. for Boston) Georeferencing / Geocoding – The process of assigning geographic coordinates to features to represent their location.

4. Geographic Information Systems (GIS) Geographic feature representation: points, lines, polygons, rasters. Points – U.S. Cities Lines – U.S. Interstates Polygons – U.S. States
