甘肃省冰湖分布数据集

本数据集基于冰川编目数据和LandsatTM/ETM+/OLI影像，结合ArcGIS和ENVI软件、NDWI和GoogleEarth影像，通过人工目视解译的方法提取距离冰川边界向外10km缓冲区内的冰湖边界。包括1990和2018年两期冰湖数据，为甘肃地区水资源评价、冰湖溃决洪水评价...

This dataset is developed using glacier inventory data and Landsat TM/ETM+/OLI imagery, combined with ArcGIS and ENVI software, the Normalized Difference Water Index (NDWI), and Google Earth imagery. Glacial lake boundaries within a 10 km buffer zone extending outward from glacier boundaries were extracted via manual visual interpretation. The dataset includes two temporal glacial lake datasets for the years 1990 and 2018, supporting water resource assessment and glacial lake outburst flood assessment in the Gansu region, ...
