The impervious surface is a part of the sub-data set in the land cover feature class. It includes the hard surfaces of roads and parking lots, but excludes the other hard surfaces, like sidewalks and buildings, etc. There are three data sources for the feature class. [1] It can be derived from the land cover feature class, where it is available within WHPAs and IPZs. [2] GIS work to buffer the road network based on the road classification and screening digitizing the parking lots from ortho images. [3] Provided from the outside organizations.
