资源简介：
A 2-meter height above ground map aka a normalized digital surface model (DSM) or canopy height model (CHM) of San Francisco, CA. The original LiDAR data and digital elevation models are provided by the United States Geological Survey at: https://rockyweb.usgs.gov/vdelivery/Datasets/.
Specifically, the 1 meter bare-Earth digital terrain model (DTM) is provided here.
The 2 meter highest LiDAR return aka digital surface model is provided here.
The 1 meter data was resampled to 2 meters with minimum pooling. The individual DTM and DSM rasters were mosaicked, and subsequently aligned in QGIS. The height above ground is calculated via: DSM - DTM.
