Remote sensing products of thermal collapse in Heihe permafrost region of the Tibetan Plateau (2009-2018)

Remote sensing products of thermal collapse in Heihe permafrost region of the Tibetan Plateau (2009-2018)

Global warming and human activities have led to the degradation of permafrost and the collapse of permafrost, which have seriously affected the construction of permafrost projects and the ecological environment. Based on high-resolution satellite images, the permafrost of oboling in Heihe River Basin of Qinghai Tibet Plateau is taken as the research area, and the object-oriented classification technology of machine learning is used to extract the thermal collapse information in the research area. The results show that from 2009 to 2019, the number of thermal collapse increased from 12 to 16, and the total area increased from 14718.9 square meters to 28579.5 square meters, nearly twice. The combination of high spatial resolution remote sensing and object-oriented classification method has a broad application prospect in the monitoring of thermal thawing and collapse of frozen soil.

File naming and required software

According to the satellite image time, each file is the image of a certain year, and also includes the corresponding collapse polygon data.
