ABSTRACT Permafrost is deeply involved in a series of geophysical processes, and it plays an important role the hydrology cycle, vegetation evolution, greenhouse gas emission. As one most sensitive indicators global climate warming, dynamic changes permafrost distribution its thermal state have been focus cryospheric change research. The highly developed remote sensing technology can provide abundant earth observation data over wide spatiotemporal range, has become powerful approach to detecting variations their related landforms. In this review, we summarize applications technologies identifying mapping typical thermokarst landforms that are closely degradation, namely, lakes, thaw slumps, bogs. We emphasize great potential using automated methods on high‐resolution optical images extraction multi‐temporal kinematic information from laser scanning interferometric synthetic aperture radar (InSAR). not only show usefulness identification landforms, but also point out several limitations future directions for further improvement.
