National Land Cover Database 2001 - Tree Canopy of Idaho (source NLCD 2001)

Published by Idaho Department of Water Resources | University of Idaho | Metadata Last Checked: August 02, 2025 | Last Modified: 2019-12-16T19:00:47.000Z
The downloadable ZIP file contains a georeferenced TIF.  The National Land Cover Database 2001 tree canopy layer was produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium. The MRLC Consortium is a partnership of federal agencies (www.mrlc.gov), consisting of the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), the U.S. Environmental Protection Agency (EPA), the U.S. Department of Agriculture (USDA), the U.S. Forest Service (USFS), the National Park Service (NPS), the U.S. Fish and Wildlife Service (FWS), the Bureau of Land Management (BLM) and the USDA Natural Resources Conservation Service (NRCS). One of the primary goals of the project is to generate a current, consistent, seamless, and accurate National Land cover Database (NLCD) circa 2001 for the United States at medium spatial resolution. For a detailed definition and discussion on MRLC and the NLCD 2001 products, refer to Homer et al. (2003) and http://www.mrlc.gov/mrlc2k.asp. The NLCD 2001 was created by partitioning the U.S. into mapping zones. A total of 66 mapping zones were delineated within the conterminous U.S. based on ecoregion and geographical characteristics, edge matching features and the size requirement of Landsat mosaics. The tree canopy layer for Idaho is comprised of mapping zones 08, 09, 10, 18, 21, 16, and 17 which encompass whole or portions of several states including the state of Idaho. Questions about the NLCD mapping can be directed to the NLCD 2001 land cover mapping team at the USGS/EROS, Sioux Falls, SD (605) 594-6151 or mrlc at usgs.gov.These data were contributed to INSIDE Idaho at the University of Idaho Library in 2007.
