Orthoimagery and elevation data derived from UAS imagery for the Midnight Meadows management area, Carson National Forest, 2018

Point cloud data set (.las), Digital Elevation Model (DEM, .tif) and orthoimagery (.tif) for the USFS Midnight Meadows fen area during initial stages of cattle exclosure and stream restoration. Aerial images of fens at the Midnight Meadows management area of Carson National Forest, New Mexico were collected on 12 September, 2018 using Unoccupied Aerial Systems (UAS, or "drones"). Data were processed using photogrammetry to generate a three dimensional point cloud that identifies pixels from multiple images representing the same object and calculates the x, y, and z coordinates of that object/pixel. The point cloud was processed to create a digital surface model of the site (6 cm resolution). Finally, source images were stitched together based on shared pixels and orthoganally adjusted to the digital surface model to create a high resolution (approximately 3 cm) orthoimage for the study area. Products capture conditions of the fen area during initial stages of cattle exclosure and installation of erosion control structures to restore hydrology and vegetation.
