Parallel algorithm for multi-viewpoint viewshed analysis on the GPU grounded in target cluster segmentation
ABSTRACTViewshed analysis is a significant method for GIS spatial analysis. The needed computational resources rise sharply with the increase in the number of viewpoints, making viewshed analysis inefficient in multi-viewpoint scenes. Building on the shadow map algorithm, a parallel algorithm for mu...
