A Novel Rapid Method for Viewshed Computation on DEM through Max-Pooling and Min-Expected Height

Viewshed computation of a digital elevation model (DEM) plays an important role in a geographic information system, but the required high computational time is a serious problem for a practical application. Hitherto, the mainstream methods of viewshed computing include line-of-sight method, referenc...
