Name: 2D Building Footprints

Display Field: ACQS_MTHD

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The 2D footprint dataset represents building roof footprint extents and should not be confused with the building industry floor footprint. This dataset was created from photogrammetrically captured 3D building models. They have been verified using land parcels, the city ortho mosaic and oblique imagery. They can be used in 2D representations and 3D scenes with a DEM. The year:month of aerial imagery acquisition used in the data capture can be found as an attribute in the feature class table, and the annually occurring additions and updates are indicated there.
