Building Footprint

Building Footprint is a packaged geospatial dataset from Mapizy, an Australian GeoAI company. Building outlines held in property, insurance and council databases often lag behind what has been built. Mapizy's AI extracts building footprints from high-resolution aerial and satellite imagery, and the company describes the resulting data as GIS-ready, with global coverage and a three-month currency, for use in enriching an existing geospatial database.

Mapizy also applies deep-learning change detection between image dates to produce building change maps that show new, removed or altered buildings. It positions these for real-estate checks on potential adverse-possession claims and on compliance with approved building plans, for property valuation, for insurers assessing building damage after bushfire and flooding, and for councils that want to update their geospatial databases more frequently.
