1. Site Selection in ArcMap (using merge, intersect, and erase)

  • Where to open a new pizzeria in the DFW Metroplex?
    • Download Data
    • Open ArcMap and add from database:
      • Pizzerias
      • CPK
      • SampleData2005
      • Landuse
      • Major Roads
    • Positive Criteria:
      • Intersect all positive criteria
        • ArcToolbox/Analysis Tools/Overlay/Intersect
    • Negative Criteria
      • Merge all negative criteria
        • ArcToolbox/Data Management Tools/General/Merge
        • (Can also use Union. As a habit I always use merge because it combines attributes which union does not do.)
    • Erase Positive Criteria with Negative Criteria [This in Student License? I am not sure!]
      • ArcToolbox/Analysis Tools/Overlay/Erase
