Urban & Developed

The terraPulse urbanization dataset maps urban cover and change as spatio-temporal estimates of impervious surface cover. The data are based on high-resolution satellite estimates of building and pavement cover, interpolated to 10- or 30-meter, annual resolution using Landsat, Sentinel, and other data sources. Through the terraPulse Land Cover Dataset, the Impervious Surface Cover layer is also available as a binary measurement at 1-meter resolution, with historical coverage depending on availability of high-resolution imagery. Certainty of continuous data products is represented as Root Mean Square Error, and certainty of categorical products is represented as probability of class membership.
