Flathead Basin Digital Elevation Model Data

These data are bare earth digital elevation models (DEM) represent the earth's surface with all vegetation and human-made structures removed. The bare earth DEMs were derived from LiDAR data using TIN processing of the ground point returns.

DEMs with a grid cell size of 3 feet were produced, and these DEMs are available. The DEMs were then processed for hydrologic correctness using photogrammetric breaklines and resampled to a cell size of 6 feet.
