CREATION OF DIGITAL ATLAS FOR LANDSLIDE HAZARD

Abstract

The assessment of landslide hazard manually is a challenging task. With the evolution of geospatial technologies like remote sensing and Geographic Information System (GIS), the estimation of the hazard has become effective and convenient. Landslide Hazard Zonation (LHZ) mapping constitutes an integral part of landslide mitigation. In order to accomplish the - objectives of LHZ mapping, various parameters of considerable importance are taken into account and each parameter serves as a thematic layer. Eventually, these layers are then integrated to produce a LHZ map. For future assistance, there is a need to organize the thematic layers and LHZ maps. The best way to do so is assembling them in the form of a book, better known as an 'atlas'. But there are various limitations bound to paper atlas like, their cost of reproduction, non-customizability, fixed frame of maps, etc. To overcome these limitations, electronic adaptation in the form of digital atlas has come to the rescue. A digital atlas is the most interactive and user-friendly form of representation till now which can carry various tools and functions like- customizability, zooming, panning, better visualization, easy navigation, etc. The digital atlas thus stands as a ready-to-help source which may assist planners and decision makers in mitigating disasters like landslide.
