  • Storing
    • Vector Data
      • Points - individual houses, stores, buildings (locations)
      • Lines – streets, networks, etc.
      • Polygons -- plots of land, neighborhoods, houses (zoomed in)
    • Raster Data
      • GIF, TIF, JPG
      • Other…
  • Map Scale determines shape & size of features
