Thematic accuracy assessment of the 2011 National Land Cover Database (NLCD). [PDF]

open access: yesRemote Sens Environ, 2017
Accuracy assessment is a standard protocol of National Land Cover Database (NLCD) mapping. Here we report agreement statistics between map and reference labels for NLCD 2011, which includes land cover for ca. 2001, ca. 2006, and ca. 2011. The two main objectives were assessment of agreement between map and reference labels for the three, single-date ...
