Elevation
LiDAR derived elevation and slopeDescription
This API includes elevation data from three sources. Two are global, one low and one moderate resolution Digital Elevation Model (DEM) and slope datasets. The third is a high-resolution lidar derived DEM, Digital Surface Model, and slope dataset for Minneosota.
