黄土高原90米分辨率坡度图(2012年）
收藏资源简介：
黄土高原90米分辨率坡度图(2012年），坡度数据是对地表坡面倾斜程度的描述，原始数据黄土高原及周边地区的SRTM从http://srtm.csi.cgiar.org/网站获取，数据为ASCII格式，按5°×5°分幅，WGS84坐标；最终数据通过投影转换、图幅拼接、数据重采样、数据裁剪得到。 数据按1:25万地图标准分幅方式划分图幅，用1:25万标准图幅号命名。
90-meter Resolution Slope Map of the Loess Plateau (2012). Slope data describes the slope inclination of the Earth's surface. The original SRTM data covering the Loess Plateau and its adjacent regions was obtained from the website http://srtm.csi.cgiar.org/. The raw data is stored in ASCII format, divided into 5°×5° tiles, and uses the WGS84 geographic coordinate system. The final dataset was generated through projection transformation, tile mosaicking, data resampling, and data clipping. The dataset is divided into map sheets according to the 1:250,000 standard topographic map tiling scheme, and named using the standard 1:250,000 map sheet numbers.
