Description
Petersham, Massachusetts is the location for these lidar-derived digital surface model (DSM) data, representing surface elevations for 'leaf-on' conditions in August 2022. The data were collected by the NSIDC_CPRD organization as part of the SMAPVEX19-22 campaign to validate satellite-derived soil moisture estimates in forested areas. The DSM captures the highest elevation of features, which may include bare-earth, vegetation, and human-made objects.
Use Cases
Validate satellite-derived soil moisture estimates based on the dataset's purpose for the SMAPVEX19-22 campaign.
Analyze forest canopy structure and height based on the DSM representing 'leaf-on' surface elevations.
Model terrain and surface features for Petersham, MA based on the lidar-derived elevation data.
Characterize land surface properties for hydrological studies based on the dataset's focus on forested land cover.
Strengths
Data is temporally specific, collected in August 2022 to characterize 'leaf-on' conditions.
