ABSTRACT
In today’s world of rapidly advancing remote sensing scenario, there area number of
possible wide application. Remote Sensing (RS) and Geographical information system (GIS)
could generate data required for micro and macro-level planning of mineral exploration in their
identification and quantitative estimation. Remote sensing as a direct adjunct to field, Lithologic
and structural mapping, and more recently GIS have played an important role in the mineralized
area. A review on the application of Remote Sensing in identification rock types like
(charnokites, mafic granulites and megacystic granites) is attempt here. The geologic remote
sensing involves the study of the earth utilizing electromagnetic radiation, which is either
reflected or emitted from the earth surface in wavelengths ranging from 0.3 micrometer to 3m.
This study included identification and quantitative estimation of Nagalla konda
reserved Forest, Kavugunta, Gantikoratam, Gunempudi Pedd& China Madina, Singavaram areas
near Vaddadi area. Two different types of satellite images were used in this study. LAND SAT
Enhanced Thematic Mapper (eight band) image and IRS P6 LISSIII images are used for all study
areas. Digital image classification was used for identification rock types and field verification
was carried out to collect ground truth data.
The quantitative analysis was carried out in the study area by using Arc GIS 3D analysis
for different rock bodies. in this analysis , TIN is used to estimate area and volume of the rock
bodies.
