What resolution is NLCD?
30m resolution
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 does NLCD mean?
EROS is central to the creation of the National Land Cover Database (NLCD), which is updated every five years and stands as the definitive land cover database for the United States.
What percentage of land cover is found on Earth?
Visualizing Countries by share of Earth’s surface There are over 510 million square kilometers of area on the surface of Earth, but less than 30% of this is covered by land. The rest is water, in the form of vast oceans.
What is land cover map?
Land cover maps represent spatial information on different types (classes) of physical coverage of the Earth’s surface, e.g. forests, grasslands, croplands, lakes, wetlands. Dynamic land cover maps include transitions of land cover classes over time and hence captures land cover changes.
What is land cover data?

Which is the latest year of NLCD data?
NLCD 2019 represents the latest evolution of NLCD land cover products focused on providing innovative land cover and land cover change data for the Nation. NLCD 2019 offers 8 integrated epochs of land cover for years 2001, 2004, 2006, 2008, 2011, 2013, 2016, and 2019.
How many time periods are there in the MRLC?
Projected data include three time periods (2020s, 2050s, and 2080s) and two climate scenarios (Representative Concentration Pathways [RCP] 4.5 and 8.5).
What is the national land cover database ( NLCD ) 2016?
National Land Cover Database (NLCD) 2016 NLCD 2016 is an ongoing land cover modeling production effort with NLCD scientists providing expertise in research and development, modeling, scripting, scene selection, cloud-masking, land cover mapping, and imperviousness mapping production.
