资源简介:
This data release contains one shapefile describing cattle access to a total of 36 different sub basins within the Smith Creek Watershed located in Virginia and West Virginia. This data release identifies areas in satellite imagery where cattle were observed to have access to the stream (confirmed access), areas where cattle exist, and are not fenced off from the stream (unrestricted access), and areas that cattle do not have the potential to enter the stream (restricted access) at the time of imagery capture. Streams were defined using a combination of geospatial data and visually assessing channel morphology in aerial imagery. Cattle access points were determined by visually assessing satellite imagery for barren or disturbed earth adjacent to stream morphology that suggest cattle paths.
