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...
withregional overall accuracies ranging from 68% to 86% for Level II and from 79% to 91% at Level I. Geographicvariation in class-specific accuracy was strongly associated with the phenomenon that regionally moreabundant land-cover classes had higher accuracy. Accuracy estimates based on several...
The NLCD (National Landcover Database) is a project that produced ecosystem coverage data for the conterminous United States in the form of raster imagery. The shades in these images each represent one of 22 defined landcover types (one of which is “not defined”). The template file that ...

为了创建一个更加不均匀和详细的Urban fraction场供NUDAPT使用,用户可以通过多分辨率土地特征联盟(Multi-Resolution Land Characteristics Consortium),从国家土地覆盖数据库(National Land Cover Database,NLCD)获得高分辨率的土地覆盖信息。Urban fraction场的生成,在WRF中称为FRC_URB2D,首先下载WRF域覆盖区域的NLCD数据,将...
