Abstract |
|
In the present study, geomorphological mapping using remote sensing techniques has been carried out in kolli hill. Uses of remote sensing and GIS methods has been proved indispensable in geomorphological study. Landforms are interpreted on the basis of interpretation element keys namely tone, texture, size, shape, color etc. and extract the specific information from the false color composites in the digital satellite images of LISS IV IRS P6 data. Geomorphological units are classified on the basis differential erosion processes. In the present investigation an attempt is being made to use the NRIS (Natural Resource Information System) standard for geomorphic mapping. The geomorphic units mapped from satellite image of Structural hills (276.84 Km2) occupying major portions of the area, and residual hills covers 0.48 Km2 covered in northeastern part, pediment 23 Km2 northern, southern and northeast portions of the area. Hilltop western (176.75 Km2) and central portions of the area. The above said information reveals that the digital satellite technology proves an efficient tool in mapping the landforms. |
