How to add Indiana LiDAR data product layers in GIS software
We are hosting below LiDAR data product tile maps derived from the Indiana 3D Elevation Program LiDAR data. Normalized Digital Height Model(NDHM): Height measured from the ground surface to the top of the objects. The spatial resolution of the NDHM layers are 100ft GSD* for statewide, 5ft GSD for countywide tile maps. Digital Terrain Model(DTM): Elevation of ground surface. Only …
