Viewshed refers to the land area that is visible to an observer placed in a point of a terrain. Due to the advances in remote sensing technologies the volume of data is today beyond the capability of traditional GIS tools and therefore new and fast algorithms become essential. In this paper we present an efficient implementation of the XDRAW algorithm  to quickly compute viewsheds on very large digital elevation models. We redesign the algorithm to make it IO-efficient and compatible withdoi:10.1109/pdp.2015.62 dblp:conf/pdp/BravoSW15 fatcat:kztdmedm5fhsfjhoyxrkthseea
