ACM SIGSPATIAL GISCUP 2022 Workshop Report: Extracting Building Footprints from LiDAR Point Clouds Seattle, Washington, USA, November 1, 2022.

The 11 th SIGSPATIAL Cup competition, GISCUP 2022, was held in conjunction with the 30 th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems (ACM SIGSPATIAL 2022), and focused on extraction of building footprints from LiDAR point clouds. Participating teams competed on computing the most accurate building footprints in selected areas, based on a given LiDAR point cloud. The point cloud was USGS data created by scanning the area using light detection and ranging. The top three teams presented their results at the SIGSPATIAL 2022 conference.
