中国1000米分辨率坡长图（2000年）

该数据集为中国坡长图，空间分辨率为1000米，数据为栅格格式，数据量105MB，投影为Albers。DEM原始数据从网站上下载，网址：（http://e4ft101.cr.usgs.gov/SRTM/SRTMGL1.003/2000.02.11/），通过投影转换、图幅拼接、数据重采样、数据裁剪，最后将投影拼接后的SRTM数据通过LS_TOOLS计算得坡长图。本数据集包含的地理空间范围是全国主要陆地，南海岛礁等区域数据待补。

This dataset is a slope length map of China, with a spatial resolution of 1000 meters, stored in raster format, with a data volume of 105 MB, and uses the Albers projection. Raw DEM data was downloaded from the website: http://e4ft101.cr.usgs.gov/SRTM/SRTMGL1.003/2000.02.11/. The SRTM data was then processed through projection transformation, map sheet mosaicking, data resampling, and data clipping. Finally, the slope length map was calculated from the processed SRTM data using LS_TOOLS. The geographic coverage of this dataset includes the main terrestrial areas of China; data for regions such as the South China Sea Islands remains to be supplemented.
