Landslide Mapping using Multitemporal Geospatial Dataset
The rapid development in remote sensing technologies has opened a new era for the acquisition of accurate and reliable 3D spatial data. Satellite images and LIDAR datasets can capture data quickly without having to make contact with hazardous areas or objects. This technique provides photorealistic 3D point clouds, which are indispensable for many fields in geoscience and engineering, particularly landslide-hazard, slope instability, and rock movement mapping. In this article, we present a study on the use of historical and new remote sensing data for mapping el-Deweika landslide that happened in September 2008. Data was collected before and after the landslide happened. We showed the importance and need for remote sensing technology to map hazardous Earth surface movements.
