Name: Building Footprints (Leading Edge Geomatics)

Display Field: OBJECTID

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Method descriptionWe developed a method that approximates the prediction pixels into polygons making decisions based on the whole prediction feature space. This is very different from standard approaches, e.g. Douglas-Peucker algorithm, which are greedy in nature. The method tries to impose some of a priory building properties, which are, at the moment, manually defined and automatically tuned. Some of these a priori properties are:The building edge must be of at least some length, both relative and absolute, e.g. 3 metersConsecutive edge angles are likely to be 90 degreesConsecutive angles cannot be very sharp, smaller by some auto-tuned threshold, e.g. 30 degreesBuilding angles likely have very few dominant angles, meaning all building edges are forming angle of (dominant angle ± nπ/2)Data VintageThe vintage of the footprints depends on the vintage of the underlying imagery. Because Bing Imagery is a composite of multiple sources it is difficult to know the exact dates for individual pieces of data.
