CALCITE MINERAL EXPLORATION IN CHILIKA LAKE USING HYPERION DATA

Mineral mining is beneficial to the country's stability and economic growth. Since there are more rocks and vegetation along the coast, minerals are yet to be found and analyzed. Nowadays, it is easier to identify minerals using satellite images by comparing their various properties. In this study, CHILIKA Lake near the Odisha State along the coast is selected for mineral exploration. EO-1 Hyperion data is used for the extraction of minerals. Mineral detection system involves the following steps for the processing of Hyperion data like spectral and spatial subsetting, FLAASH atmospheric Correction, Minimum Noise Fraction (MNF), Pixel Purity Index (PPI), n-dimensional Visualizer, Spectral Angle Mapper (SAM), and Spectral Analyst. By comparing the surface reflectance curve available in the USGS (United States Geological Survey) database for identification, the result confirms that Calcite mineral is abundant in the field, and the probability score for calcite is found to be extremely high in this region. Calcite is a rock-forming mineral that is mostly used in the concrete, abrasive, agricultural soil disposal, construction aggregate, dye, medicinal, acid neutralizer, monuments, and sculptures industries. ENVI software was used to analyze the results.
