资源简介:
The data publication contains 1 meter raster data sets for three different digital elevation models (DEM) for the Priest River Experimental Forest in north Idaho in 2002. The first is a digital terrain model (DTM), which is the ground surface with all vegetation and human-made structures removed. The second is a digital surface model (DSM), which includes all vegetation and human-made structures. The last is a canopy height model (CHM), which is the difference between the DSM and the DTM surfaces. Provide high resolution terrain elevation and land cover elevation data for the Priest River Experimental Forest. These data are a newer edition of the Hudak et al. (2013, https://doi.org/10.2737/RDS-2013-0001) data publication. This second edition corrects height discrepancies that were found between 2002 and 2011 lidar data. The 2002 lidar data were corrected by adding 16.5 meters to the height value of each lidar return, and DTM and DSM surfaces. A newer algorithm was used to classify returns as ground and nonground, and create the CHM surface. This 2nd edition was published on 06/24/2020. On 07/10/2020 we updated the metadata to include a cross-reference for a newly published Priest River Experimental Forest data publication that contains similar data for 2011.
