During late Fall of 2015 the Utah Division of Foresty, Fire & State Lands and the U.S. National Park Service acquired ~152 square miles covering ~680 river miles of 8 points per meter LiDAR of the Colorado, Green, and Yampa rivers in Utah and Colorado. The LiDAR collection is mainly of the river course and not the surounding canyons. A small ~.8 square mile area was also collected in Arches N.P. The .5 meter resolution bare earth DEMs and first-return/highest-hit DSMs in .tif format have a 10.0cm vertical RMSE accuracy and are available for download. The LAS classified point clouds are also available by request from Rick Kelson from AGRC at RKelson@utah.gov, or Buck Ehler from DNR at BuckEhler@utah.gov This elevation data was collected October and November of 2015 during low flow conditions.
