Taking Sichuan power grid for example

the potential landslides in power grid covers a wide range and is hard to be detected. The traditional manual investigation is weak

which cannot meet the requirements and accuracy of potential landslide detection and landslide deformation analysis in a wide mountainous area. Satellite remote sensing

unmanned aerial vehicle (UAV) remote sensing and ground survey technology are proposed to be carriers

and it will bring into full play the advantages of multiple-domain technology

including the wide coverage and strong repetitive observation ability of satellite remote sensing

and strong maneuverability and high resolution of UAV remote sensing

so as to realize the multidimensional means such as "general investigation"

"detailed assessments" and "investigation"

which solves the difficulties of detecting potential landslide from the source. Taking a certain 500 kV overhead transmission as research object

the early detection of potential landslide is successfully carried out based on an integrated space-air-ground investigation system.
