This document discusses the use of GIS and remote sensing tools to analyze landslides. There are three main causes of landslides: geological factors related to rock/soil strength, morphological factors related to slope and vegetation, and human activities like construction. GIS and remote sensing can be used to map landslide hazards by analyzing contributing factors at different scales from national to site-specific. The methodology involves defining objectives, selecting an appropriate analysis scale, collecting relevant data layers, and producing hazard zonation maps showing susceptibility and probability of landslides.
