Landslides are the result of interaction among several terrain parameters. Therefore, it is always necessary to study different terrain parameters, which contribute to slope instability in a hilly terrain in order to understand the landslide phenomena. The present paper deals with preparation of few important terrain parameter maps of Darjeeling Himalaya and the spatial distribution of their different classes. Few landslides identified on satellite imagery with limited field checks, are studied to determine their frequency distribution with the terrain parameters. The paper describes the utility of remote sensing and GIS for generation of these thematic layers and an integrated approach to evaluate layer-wise influence on landslide occurrence.
