EnviroAtlas - Sonoma County, CA - Meter-Scale Urban Land Cover (MULC) Data (2013)

Description

The EnviroAtlas Sonoma County, CA Meter-scale Urban Land Cover (MULC) data were generated from four-band (red, green, blue, and near infrared) aerial photography and LiDAR data at 6-inch spatial resolution, collected in late 2013, as well as ancillary vector data (e.g., roads, agriculture, wetlands) provided by the Sonoma County Vegetation Mapping and LiDAR Program (http://Sonomavegmap.org). Ten land cover classes were mapped: water, impervious surfaces, soil and barren land, trees, shrub, grass-herbaceous non-woody vegetation, agriculture, orchards, as well as woody wetlands and emergent herbaceous wetlands. An accuracy assessment of 629 completely random and 176 stratified random photo-interpreted reference points yielded an overall MAX accuracy of 79 percent and an overall RIGHT accuracy of 80 percent (See overview section for more details on accuracy assessment). The area mapped is Sonoma County, CA. This dataset was produced by the Sonoma County Vegetation Mapping and LiDAR Program and the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).
