Abstract :

Geomorphometry is the science of quantitative land surface analysis. It gathers various mathematical, statistical and image processing techniques that can be used to quantify morphological, hydrological, ecological and other aspects of a land surface. Geomorphometry aims at extracting land surface parameters and objects using input digital land surface model and parameterization software. Extracted surface parameters and objects can then be used, for example, to improve mapping and modelling of soils, vegetation, land use, geomorphologic and geological features and similar. This paper discusses some of the applications of GIS in areas like geomorphologic studies, land use evaluation, watershed management and so on.
