Geometry of building footprints are extracted automatically through aerial imagery or very high resolution satellite data optional via integration of surface height data (eg.airborne laserscan or satellite derived). The building footprint are defined as the aerial visible first floor projection at grade to the edge of built area including conditioned and non conditions spaces: living area, decks, garages, porches, etc.). Building footprint data can be provided as a raster based layer or vector based format, optionally with individual building attributes (such as height, footprint area, type etc.)..

Common applications of building footprint data include
For custom production the costs are largely determined by customer supplied image data, minimum mapping units (=smallest object identified) and mapping accuracies needed. Existing building footprint database:

Optionally, the building footprints can be cartographically corrected to fit with existing geodata (such as Tele Atlas/Tom Tom MultiNet data). Moreover, other infrastructures of interest can be captured as well.
