An attempt is made to study the significance of morphometry, integrating Remote Sensing data and
techniques in addition to the conventional methods in a GIS platform. The Western Ghats are amongst the
eighteen biodiversity hot-spots recognized globally (WCMC, 1992) and are known for their high levels of
endemism. Kodaikkanal Hills are parts of Palani hills of Western Ghats. The study has demonstrated the
potential use of remotely sensed data and Geographical Information Systems (GIS) in evaluation of linear, relief
and areal morphometric parameters and to analyze their influence on the genesis and processes of landforms
and characteristics of soil parameters like texture, drainage and land erosion conditions. Visual interpretation
of satellite data in analysis of geological, landforms and land erosion characteristics in conjunction with
drainage pattern facilitates effective delineation of distinct features to evaluate the influence of drainage
morphometry. GIS is an effective tool to analyze spatial and non-spatial data on drainage, geology, landforms
and soil parameters to understand their inter-relationships. Geo-coded resource database generated on drainage,
landforms and soil parameters in the core of GIS provides an excellent means of storing, retrieving and
analyzing data at river basin level to find out their association. It also provides a powerful mechanism not only
to upgrade and monitor morphometric parameters but also to permit the spatial analysis of other associated
resources database. An attempt has been made to utilize the interpretation capabilities of GIS to find out the
relationships between the morphometric parameters at sub basin level.
Key words: Bio diversity hotspots, GIS, land form, morphometry, relief, slope, remote sensing
