Summary

The USGS, in cooperation with the U.S. Bureau of Land Management (BLM), created a series of geospatial products of the Scotts Creek Watershed in Lake County, California, using National Agriculture Imagery Program (NAIP) imagery from 2018, 2020 and 2022. The imagery was downloaded from United States Department of Agriculture (USDA) - Natural Resources Conservation Service (NRCS) Geospatial Data Gateway (https://datagateway.nrcs.usda.gov). The NAIP imagery from 2018, 2020 and 2022 was classified using Random Forest Modeling to produce land cover maps with three main classifications – bare, vegetation, and shadows. A total of 600 independent reference points were used in the accuracy assessment. The overall accuracy for all classes [...]

Purpose

This data release includes a description of the geospatial data and geoprocessing steps used to create the land cover maps for the Scotts Creek Watershed, Lake County, CA. The land cover maps were created to show the spatial distribution of bare and vegetated areas to support hydrologic modeling. They represent bare, vegetated and shadow classes derived from NAIP imagery collected in 2018, 2020, and 2022. The intended uses of the land cover maps include, but are not limited to, comparisons of the spatial distribution of land cover types in 2018, 2020, and 2022 for subbasins in the Scotts Creek Watershed.
