TXT-tool 1.081-3.1 Landslide recognition and mapping using aerial photographs and google earth

Abstract

To detect landslides using topographic maps and aerial photographs, it is necessary to know the topographic features characteristics of landslides i.e., the “landslide signature” (Pike in Math Geol 20(5), 1988) and how landslide topographic characteristics differ from the topography around a landslide. In this landslide teaching tool, representative topograhic features of landslides are discussed as a means to identify them in representations of terrain such as topographic maps and aerial photographs. Several examples and indications for this recognition tool are presented. Finally, the use of satellite images and terrain modeling in Google Earth to detect and map landslides is demonstrated as well.
