The three largest countries in North America share trade, climate and culture in a host of broad and specific ways. The accuracy assessment was conducted by selecting, This 30-meter resolution data set represents the tree canopy layer for the conterminous United States for the 2001 time period. The National Land Cover Database (NLCD) provides nationwide data on land cover and land cover change at a 30m resolution with a 16-class legend based on a modified Anderson Level II classification system. Nationally standardized, raster-based inventories of land cover for the coastal areas of the U.S. Data are derived, through the Coastal Change Analysis Program, from the analysis of multiple dates of remotely sensed imagery. A lock () or https:// means youve safely connected to the .gov website. A main objective of releasing these maps is to provide a tool for better monitoring EAG dynamics and informing conservation and management efforts at local to regional scales. USGS is currently working in partnership with the Interagency Multi-Resolution Land Characteristics (MRLC) Consortium to produce the next version of the National Land Cover Database, NLCD 2019. For pixels with 1-25% tree canopy cover we ensured that our primary components (shrub, herbaceous, litter, and bare ground) cover summed to 100% when added with the tree canopy. NLCD supports a wide variety of Federal, State, local, and nongovernmental applications that seek to assess ecosystem status and health, understand the spatial patterns of biodiversity, predict effects of climate change, and develop land management policy.

The NLCD 2019 design aims to provide innovative, consistent, and robust methodologies for production of a multi-temporal land []. NLCD 2011 provides - for the first time - the capability to assess wall-to-wall, spatially explicit, national land cover changes and trends across the United States from 2001 to 2011. More than 75% of the tree species maintain their leaves all year. Small features and changes should be verified with a higher-resolution data source. Because of file size limitations, individual component products are packaged in three historic intervals including 1985-1995, 1996-2006, and 2007-2021. The latest evolution of NLCD products are designed for widespread application in biology, climate, education, land management, hydrology, environmental planning, risk and disease analysis, telecommunications and visualization. It also includes a matching impervious surface descriptor layer. Pixels were derived from the NLCD provides spatial reference and descriptive data for characteristics of the land surface such as thematic class (e.g., urban, agriculture, and forest), percent impervious surface, and percent tree canopy cover. 2011. derived from the 2018 NavStreets Street Data.
