Subtypes and domains

  • Create a sidewalks feature class. Polygon / import spatial reference from other campus data.
  • Add fields for Width (integer), Material (Integer), and Condition (Text)
  • Add coded value domains to the geodatabase - Width (2,4,6), Material ( 1= Concrete, 2 = Asphault, 3 = Gravel). Condition (Good, Fair, Poor)
  • Apply domains to fields
  • Create subtype for Material - Default concrete
  • Apply default values and domains to subtypes (Concrete- condition = Good, width = 4)(Asphault- condition = Fair, width = 4)(Gravel- condition = Poor, width = 2)
  • Go into ArcMap, add sidewalks and start editing. Notice the functionality subtypes and domains give to the editing process.
