What is NLCD 2011?
National Land Cover Database 2011 (NLCD 2011) is the most recent national land cover product created by the Multi-Resolution Land Characteristics (MRLC) Consortium. 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.
How accurate is NLCD%IC?
NLCD %IC is a useful proxy for high-resolution %IC except for small urbanized areas. The emergence of high-resolution land cover data has created the opportunity to assess the accuracy of impervious cover (IC) provided by the National Land Cover Database (NLCD).
What is the resolution of NLCD 2011 land cover classification?
As with two previous NLCD land cover products NLCD 2011 keeps the same 16-class land cover classification scheme that has been applied consistently across the United States at a spatial resolution of 30 meters. NLCD 2011 is based primarily on a decision-tree classification of circa 2011 Landsat satellite data.
What are the advantages of NLCD?
A significant advantage of NLCD is that it provides a consistently measured, nationwide source of %IC, thereby facilitating comparison of aquatic and other environmental responses to changes in %IC across space and time using consistently measured data.
