Summary
The USGS, in cooperation with the U.S. Bureau of Land Management (BLM), created a series of geospatial mapping products of the Scotts Creek Watershed in Lake County, California, using National Agriculture Imagery Program (NAIP) imagery from 2018, 2020 and 2022 and Open Street Map (OSM) from 2019. The imagery was downloaded from United States Department of Agriculture (USDA) - Natural Resources Conservation Service (NRCS) Geospatial Data Gateway (https://datagateway.nrcs.usda.gov/) and Geofabrik GmbH - Open Street Map (https://www.geofabrik.de/geofabrik/openstreetmap.html), respectively. The imagery was classified using Random Forest (RF) Modeling to produce land cover maps with three main classifications - bare, vegetation, and shadows. [...]

The imagery was classified using Random Forest (RF) Modeling to produce land cover maps with three main classifications - bare, vegetation, and shadows. An updated roads and trails map for the Upper Scotts Creek Watershed, including the BLM Recreational Area, was created to estimate road and trail densities in the watershed. Separate metadata records for each product (Land_Cover_Maps_Scotts_Creek_Watershed_CA_2018_2020_2022_metadata.xml, and Roads_and_Trails_Map_Upper_Scotts_Creek_Watershed_CA _2022_metadata.xml) are provided on the ScienceBase page for each child item. Users should be aware of the inherent errors in remote sensing products.

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 and an updated roads and trails map for the Upper Scotts Creek Watershed, Lake County, CA. The land cover maps were created to show the spatial distribution of bare and vegetated areas. 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. The intended uses of the updated roads and trails map include, but are not limited to, comparisons of roads and trails densities in 2022 for subbasins in the Upper Scotts Creek watershed and erosion potential in the BLM Recreational Area.
