LiDAR point density data (9/m^2 point spacing), available for years 2010 and 2011, was used to map most areas of Pierce County, and supplemental LiDAR data, available for earlier years, was used to map area segments where 2010-2011 LiDAR data was not available. A 7-band stack consisting of 1-meter, four-band (red, green, blue, and near-infrared) aerial photography, Normalized Difference Vegetation Index (NDVI), and lidar-derived intensity and height above ground was created and primarily used to classify land cover using Genie Pro automated feature extraction software. Several ancillary datasets, such as hydrographic and transportation feature data, were edited in ArcGIS and integrated into the classification workflow. The Tacoma, WA land cover dataset includes data for the Tacoma metropolitan area of Pierce County, WA, and encompasses a total approximate area of 1,995 square kilometers. The thematic landcover data is confined to areas included within the US Census Bureau's 2010 Urban Statistical area boundaries for Pierce County, WA, with an additional 1km buffer extension that include bits of Kitsap, King and Thurston Counties. The following seven land cover classes were mapped: Water, Impervious, Soil or Barren, Trees or Forest, Grass or Herbaceous, Woody Wetlands and Emergent Wetlands. Mapped water bodies were generated using combined high-resolution LiDAR and ancillary hydrological data. Integrated wetland features were derived using ancillary National Wetlands Inventory (NWI) polygon data (version 2), downloaded from the Unites States Fish and Wildlife Service (USFWS) Wetland Mapper web mapping service (https://www.fws.gov/wetlands/data/mapper.html). Metadata for the NWI wetlands data layer can be found at http://www.fws.gov/wetlands/Data/Metadata.html. An accuracy assessment of the classified product, using 482 completely random and 46 (Soil/Barren) stratified random photo-interpreted land cover reference sample points yielded an overall user's accuracy (MAX) of 85.1 percent and a fuzzy user's accuracy (RIGHT) of 86.9 percent. For data workflow processing details see Overview Description section. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (http://enviroatlas.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 (http://enviroatlas.epa.gov/EnviroAtlas/DataFactSheets). The Meter-scale Urban Land Cover (MULC) map product serves as a spatially-detailed basemap from which multiple human and ecosystem health metrics and services are calculated using the EPA EnviroAtlas tool. This MULC dataset currently represents the most detailed and accurate land cover for Tacoma and surrounding areas of Pierce County, WA. The EnviroAtlas MULC provide spatially detailed foundational data for approximately 100 derived EnviroAtlas Community information layers. For example, layers derived from MULC data include: Percent impervious area in 50m stream buffer; Value of asthma exacerbation cases avoided due to sulfur dioxide removed ($/yr); Percent of tree cover near busy roadways. Some of the many possible applications of MULC include: Knowing the exact location and size of vegetated and non-vegetated spaces; Identifying highly impervious areas that would most benefit from additional trees and other vegetation to mitigate surface runoff and urban heat island effects; Measuring the width and character of urban riparian and street buffers; Locating potential wildlife corridors, gaps and linkages; Planning park development for maximum benefits. The overall goal of EnviroAtlas is to employ and develop the best available science to map indicators of ecosystem services production, demand, and drivers for the nation. The EnviroAtlas National Component is based on NLCD (National Land Cover Database, www.mtlc.gov) land cover data at 30m spatial resolution. For some analysis, however, the density and heterogeneity of an urban landscape requires higher resolution land cover data. MULC data were developed to fulfill that need. To illustrate, there are 900 MULC pixels (1 x 1m2) for every 1 NLCD pixel (30m x 30m). This allows for the analysis of common urban landscape features in the 1-10m range, which are unresolvable using 30m NLCD pixels. completed EnviroAtlas Coordinator U.S. Environmental Protection Agency, Office of Research and Development - Center for Public Health and Environmental Assessment (CPHEA), EnviroAtlas Geospatial Data Owner 919-541-3832 (919) 541-4329 109 T.W.
