资源简介:
This is a shapefile of watershed boundaries for CONUS using 12-digit Hydrologic Unit Codes. Data are projected into the WRF-Hydro Lambert Conformal Conic (variant) spatial reference system. This is defined as \"+proj=lcc +lat_1=30 +lat_2=60 +lat_0=40.0000076293945 +lon_0=-97 +x_0=0 +y_0=0 +a=6370000 +b=6370000 +units=m +no_defs\"
本数据集为针对美国本土(Continental United States, CONUS)、采用12位水文单元代码(Hydrologic Unit Codes)的流域边界形状文件(shapefile)。数据采用WRF-Hydro兰伯特共形圆锥(变体)空间参考系统进行投影。该空间参考系统的定义为:"+proj=lcc +lat_1=30 +lat_2=60 +lat_0=40.0000076293945 +lon_0=-97 +x_0=0 +y_0=0 +a=6370000 +b=6370000 +units=m +no_defs"
