Applying Lightweight UAV in Landslide Monitoring

Abstract:

With the advantages of small size, cost efficient, low noise, energy saving, fine definition and high current, UAV has been widely used in various fields such as military, agriculture, forestry,meteorology, environment, etc. Moreover, this technique can obtain large area, large angle and 3D surface information without shadows resulting from cloud cover which is the common shortage insatellite images, it is also widespread in geological hazards monitoring. In this article, the applications of hazards monitoring using UAV has been reviewed at first, then according to the needof landslide monitoring, based on UAV data processing in geological hazard in east-north of Chongqing on 31th August, 2014, route planning method for lightweight and low altitude UAV inmountainous district is introduced, also the workflow and relevant experiences of UAV data processing by applying Agisoft photoscan software. After data processing, both geo-referencedDSM and DOM of landslide are obtained by interpolation with assistance of chosen GPS control points. The interpolated topographic map of landslide can provide important information forgeological hazards monitoring and emergency relief.
