Thematic accuracy of MRLC land cover for the eastern United States

One objective of the MultiResolution Land Characteristics (MRLC) consortium is to map general land-cover categories for the conterminous United States using Landsat Thematic Mapper (TM) data. Land-cover mapping and classifica tion accuracy assessment are complete for the eastern United States. The ac curacy assessment was based on photo-interpreted reference data obtained fr om a stratified probability sample of pixels. Agreement was defined as a ma tch between primary or alternate reference Land-cover labels assigned to ea ch sample pixel and the mode (most common class) of the map's land-cover la bels within a 3 x 3-pixel neighborhood surrounding the sampled point. At 30 -m resolution, overall accuracy was 59.7% at an Anderson Level II thematic detail, and 80.5% at Anderson Level I. (C) 2001 Elsevier Science Inc. All r ights reserved.
