TXT-tool 1.081-2.2: Landslide mapping through the interpretation of aerial photographs and topographic maps

Abstract

Processes of formation of topography and slopes are the result of a comprehensive combination of climatic change and crustal movement. When examining long time-scales, it is necessary to examine variations in internal and external stresses to understand the formative history of the topography. In this manual, the steps for understanding landslides will be described. The concept and frameworks for identifying unstable slopes (landslide topography) using aerial photos and topographic maps are introduced in details.
