What is NLCD land cover?
What is NLCD land cover?
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. The database is designed to provide cyclical updates of United States land cover and associated changes.
What years are NLCD layers available?
NLCD 2019 offers land cover for years 2001, 2003, 2006, 2008, 2011, 2013, 2016, 2019, as well as impervious surface and impervious descriptor layers for each epoch.

Is NLCD data raster?
The National Land Cover Dataset (NLCD) 1992 is a raster land cover map developed by the U.S. Geological Survey (USGS) for the conterminous United States at a spatial resolution of 30 meters.
What is NLCD derived from?
NLCD classification schemes are based primarily on Landsat satellite data along with ancillary data sources, such as topography, census and agricultural statistics, soil characteristics, wetlands, and other land cover maps.
How do I open NLCD data?
To open the nlcd data in qGIS, go to “Layer” in the top menu and click “Add Raster Layer”. Browse to where you saved the nlcd folder and click on the only file in there (a tif file). When it opens, it should like something like the image below. Pretty!
How do I download land cover data from USGS?
NLCD products are created by the Multi-Resolution Land Characteristics (MRLC) Consortium, a partnership of Federal agencies led by the U.S. Geological Survey. All NLCD data products are available for download at no charge to the public from the MRLC Web site: https://www.mrlc.gov/.
What is land cover classification?
The definition of land cover is fundamental, because in many existing classifications and legends it is confused with land use. It is defined as: Land cover is the observed (bio)physical cover on the earth’s surface. Also, it is disputable whether water surfaces are real land cover.
What imagery is NLCD primarily derived from?
What is developed open space?
Definition: Developed, Open Space – Areas with a mixture of some constructed materials, but mostly vegetation in the form of lawn grasses, and impervious surfaces accounting for less than 20% of total cover.
