Datasets description

This dataset is based on historical glacial lake disaster data, using Landsat, Sentinel, Planet and other high-resolution remote sensing satellite images. Based on the characteristics of glacial lake area, lake sedimentation, breaches, residual dam bodies, flood erosion and accumulation, the authenticity and reliability of historical glacial lake disaster data in the study area are verified. Using remote sensing technology and platforms to extract relevant parameters such as glacial lake area, water volume, dam body, and impact range, and to revise or supplement event data to improve the historical glacial lake disaster database in the research area. Since 2010, there have been a total of 19 incidents of collapse in the China Pakistan Economic Corridor. The dataset of glacial lake outburst floods provides basic data for disaster prevention and mitigation, glacial lake outburst flood evaluation, and glacial lake hydrological research in the China Pakistan Economic Corridor region.

Data processing method

1. Collection and screening of historical disaster data: Collect GLOF events in the China Pakistan Economic Corridor from various channels and screen for events that have occurred since 2010.

2. Verification of disaster events: False color synthesis of Landsat and Sentinel-2 satellite images, based on Landsat, Sentinel and other high-resolution remote sensing satellite images, using characteristics such as glacial lake area, lake sedimentation, breaches, residual dam bodies, flood erosion and accumulation, to verify the reliability of the collected GLOF events.

3. Parameter extraction: Using remote sensing technology and platforms to extract relevant parameters such as glacial lake area, water volume, dam body, and impact range, correcting or supplementing event data, and improving the historical glacial lake disaster database in the research area

4. Interaction inspection and quality control: Further verify the reliability of events through interaction inspection.

Data quality description

The glacial lake outburst flood event has undergone strict quality control, and each event has corresponding evidence, with a reliability of over 95%.
