DSM
The Digital Surface Model (DSM) represents the orthometric elevations of all above ground features detected by the lidar returns. It is created using the max elevation detected for each pixel at the desired resolution.
For this version of the DSM, the 2022 Bare Earth DSM was reprojected from UTM Zone 10 (with surface elevation pixel values in meters) to CA State Plane II (with pixel values in feet). These lidar-derived data products are provided to Sonoma County as part of a larger 10-county effort to acquire lidar and prepare derivative products. Dates of collection vary by county and the best available (most recent and highest quality) point cloud data was used for any given area. The various point clouds were harmonized into a single, unified point cloud for the counties. From the unified point cloud, 36 raster lidar derivatives were created for each county. See the datasheet (https://tukmangeospatial.egnyte.com/dl/ADWSBBL7ac ) for information on collection dates and to access the original DSM (in UTM Zone 10N, meters), lidar point cloud, and other derivative products.
