These data were combined into a seamless elevation surface, or topobathy dataset and released in 2016. While topobathy datasets exist for each UMRS pool, this topobathy \u201cfootprint\u201d serves as a quick reference tool to the location, extent, and metadata associated with each pool\u2019s lidar and bathymetry coverage.
