Recently Microsoft released the information of 124,885,597 estimator generated edifice footprints inwards the United States. The edifice footprints were generated past times preparation estimator vision algorithms to recognize edifice geometries on aerial imagery of the USA. Microsoft has made the information gratuitous to download nether an Open Data Commons Open Database License.
Obviously Microsoft's USBuildingsFootprints is a neat resources for U.S. map makers. However earlier using the information you lot mightiness desire to explore if it is check for purpose. Computer vision artificial tidings is an emerging scientific discipline together with is non gratuitous from error. You mightiness hence desire to explore the accuracy of the information earlier using it.
Dan Cookson's New York Buildings allows you lot to explore the accuracy of Microsoft's edifice footprint information inwards New York. It does this hold out overlaying the information on exceed of Here aerial imagery. Using the map you lot tin compare the Microsoft edifice footprints to the actual buildings shown inwards the aerial imagery. You tin equally good brand straight comparisons betwixt Microsoft's edifice footprints together with New York City's opened upwards buildings information together with edifice footprints from Open Street Map.
In New York OSM together with the local say-so information appears to hold out to a greater extent than accurate than Microsoft's edifice footprint data. The Microsoft edifice footprints oft seem to conflate a pose out of buildings inwards a block into i or to a greater extent than larger buildings. It looks to me similar Microsoft's information is reasonably accurate inwards determining the score of edifice embrace inwards an surface area but less accurate inwards defining every private edifice footprint (at to the lowest degree inwards New York). Of assort Microsoft's information mightiness nonetheless hold out check for purpose. It simply depends on how accurate you lot withdraw your edifice information to be.
