In short, we dont yet know the story of NLCD project impact. A comprehensive assessment strategy is thus needed to gauge the reach and influence of the Nations land cover database project and tell the story of its importance. Traditional measures of impact such as citation counts should of ...

The 2016 National Land Cover Database (NLCD) product suite (available on www.mrlc.gov), includes Landsat-based, 30 m resolution products over the conterminous (CONUS) United States (U.S.) for land cover, urban imperviousness, and tree, shrub, herbaceous and bare ground fractional percentages....
The U.S. Geological Survey (USGS), in partnership with several federal agencies, has developed and released four National Land Cover Database (NLCD) products over the past two decades: NLCD 1992, 2001, 2006, and 2011. These products provide spatially explicit and reliable information on the Na...
Maps of developed land from the National Land Cover Database (NLCD) of the conterminous United States include rural roads inthe developed land class and therefore overestimate the amount of urban land. To better map the urban class and understand how urban lands change over time, we removed ...
1.For that,four global land cover products were firstly compared with the national land cover dataset 2000(NLCD-2000)at provincial,regional and national scales to evaluate the accuracies of estimation of aggregated cropland area in China.该研究以中国耕地类别为研究对象,选择2000年中国土地利用数据(NL...
Several regional urban land use and UCPs datasets have been developed to initialize urban climate models. In the United States, the National Land Cover Data (NLCD) provides a 30 m resolution land cover data (Wickham et al., 2014), and the National Urban Database and Access Portal Tool (...
Two datasets of percent urban tree canopy cover were compared. The first dataset was based on a 1991 AVHRR forest density map. The second was the US Geological Survey’s National Land Cover Database (NLCD) 2001 sub-pixel tree canopy. A comparison of these two tree canopy layers was conducte...
