Clean Ice and Debris covered glaciers of HKH Region

The comprehensive baseline information on the glaciers of the HKH region was generated semi-automatically using more than 200 Landsat 7 ETM+ images of 2005 ± 3 years with minimum cloud and snow coverage. The glacier outlines were derived by using object-based image classification method separately for clean-ice and debris-covered glaciers with some manual intervention. The attribute data were assigned to each glacier using 90m resolution SRTM DEM. This data does not cover the China part.

该HKH地区冰川的全面基准信息系通过半自动化的方式生成，利用了2005年前后±3年间的超过200张Landsat 7 ETM+影像，这些影像具有最低的云和积雪覆盖率。冰川轮廓通过基于对象的图像分类方法分别对干净冰川和覆盖有碎屑的冰川进行提取，并辅以一定的手工干预。每个冰川的属性数据均通过90米分辨率的SRTM数字高程模型（DEM）分配。本数据集未涵盖中国境内。
