![]() Each polygon (or multi-polygon for non-simply connected regions) represents a building footprint. The label contains a list of polygons contained within the sub-region stored in a geoJSON format.The three-band image is derived from a panchromatic image and a subset of the three channels - the details of the derivation are available from the WorldView 2 specifications. The 8-band raster image, at roughly 2 m ground sampling distance, contains both visible spectrum channels and near infrared channels with 16-bit values.The 3-band raster image, at roughly 0.5 m ground sampling distance, contains Red, Green, and Blue color channels with 8-bit values.For each sub-region, there are two images (GeoTIFFs) and one label (geoJSON): More information on SpaceNet is available here.
