This approach enables high-resolution acquisitions of landslides. The concept of manual controlled quad-rotor helicopters has been investigated for photogrammetric applications, since quad-rotor systems have been proved to be well suited for landslide monitoring in difficult alpine terrain. During the UAV-based remote sensing campaigns significant numbers of airborne photographs of the Super-Sauze landslide (Southern France) have been acquired. These photographs were combined to an ortho-mosaic by applying plane image rectification methods. Digital surface models (DSMs) were generated using a new feature-based surface reconstruction approach which does not require any ground control point information. 1. INTRODUCTION UAVs. Today
