LiDAR Data

LiDAR is a laser imaging technology that can produce a three-dimensional model of the land surface and objects on the land surface, such as vegetation and structures. The Flathead Basin was imaged between September 22 and September 29, 2009. Two data sets are available. The "All returns" data contains x, y, and z coordinates of all objects that were imaged, post-processed to remove noise, birds, haze, and smoke. The "Grounds" data has been processed to include only points that are on the ground.

These data are in Montana State Plane coordinates, NAD83, HARN. The horizontal units of the coordinate system are U.S. Survey Feet. The vertical datum is NAVD 88, Geoid03.
