About this dataset

This raster dataset represents land cover classifications for Napa County, California, for the year 2008. It is derived from the Annual National Land Cover Database (NLCD) Collection 1, Version 1.1 (June 2025), produced by the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center. The Annual NLCD product combines methodologies from the National Land Cover Database (NLCD) and Land Change Monitoring, Assessment, and Projection (LCMAP) programs with modern geospatial deep learning techniques to produce annual, high-resolution land cover maps. The dataset provides annual land cover classifications for the conterminous United States (CONUS) from 1985 through 2024 at a 30-meter spatial resolution using a modified Anderson Level II classification system consisting of 16 land cover classes. Source data are derived from Landsat Analysis Ready Data (ARD) processed through the Land Cover Artificial Mapping System (LCAMS), a multi-stage deep learning architecture. This derivative dataset was prepared by the Napa County Planning, Building and Environmental Services (PBES) GIS Division for the Baseline Data Report (BDR) and General Plan Update (GPU) Land Cover Change Analysis. The source raster was reprojected from the native Annual NLCD Albers Equal Area CONUS coordinate system (EPSG:5070) to NAD83 California State Plane Zone II (WKID 2226, US Survey Feet) using Nearest Neighbor resampling to preserve the original land cover classifications, then clipped to the Napa County administrative boundary. Napa County encompasses approximately 507,000 acres in the North San Francisco Bay Area of California. This dataset is one of a 20-year annual time series (2005–2024) used to evaluate land cover change at the countywide scale and within the 13 Geographic Evaluation Areas (GEAs) established for the Napa County General Plan Update. The analysis documents changes associated with agricultural expansion, urban development, and major wildfire events, including the 2017 Atlas and Nuns Fires and the 2020 LNU Lightning Complex Fire.
