Mineral Exploration Using Satellite Imagery

Abstract

Minerals and some crucial rock exploration techniques have been described in this thesis.Mineral exploration is the process where Satellite or remote sensing instrument are necessary. Satellite image processing is used for mineral detection. For finding mineral, several satellite like Landsat satellite, Terra satellite band technology and some advanced sensor like TM, OLI, TM have their usages. Satellite active and passive sensorsare very important for sensing minerals. This sensor supportsin to collect electromagnetic spectral band extraction.Satellite spectral band1 to band 9 haveusage in Landsat 8 satellite. Landsat 8 is more effective to find out the minerals.This band are the part of electromagnetic spectrum which help to distinguish the mineral reflectance characteristic and absorption band features. The earth object spectral characteristics is different which contain several color combinations like True color, False color and Band ratio technique help to identify the minerals.Some remote sensing software are used to understand the picture and enhance the picture quality. Thermal imaging is another method which identifies the earth surface minerals temperature. Thermal behavior of altered minerals can detect by Satellite Thermal sensor camera and record the information and it can display different color for different mineral and help us to distinguish minerals.
