We emphasize accuracy to support better outcomes of using our Geometry data. For the most popular branded POIs important to our customers, we hand draw polygons to ensure they are close to 100% accurate. Our technical documentation outlines which building footprints are hand drawn and which are machine generated, so you know exactly what data you are working with.
Spatial hierarchy is a key aspect of our polygon data, representing the relationship between two or more polygons. This allows you to understand if a polygon includes a parking lot, if it shares a building footprint with another POI, if it’s a child or parent to another POI, and more.
