| Description | Raster files and point clouds from 2010 and 2017 LiDAR capture covering New York City. The 2010 LiDAR includes one hydro-flattened digital elevation model (DEM). The 2017 LiDAR includes classed and unclassed point clouds in laz format, bare earth DEM, hydroflattened DEM, hydro-enforced DEM (filled and unfilled), highest hit, intensity imagery, 8-class land cover, and tree canopy change (2010-2017). |
