This article presents T iled VS, a fast external algorithm and implementation for computing viewsheds. T iled VS is intended for terrains that are too large for internal memory, even more than 100,000×100,000 points. It subdivides the terrain into t

We present a fast linear time algorithm that uses a block-cut tree for identifying upstream features from a set of starting points in a network. Our implementation has been parallelized and it can process a dataset with 32 million features in less th
