An Analogical Study Between Lateritic Index and an Innovative Index to Enhance Detection of Bauxite in Ranchi and Lohardaga in Jharkhand, India using Sentinel 2A Data

The primary objective of this study is to determine and assess the accessibility of bauxite in Jharkhand, which involves some specific regions such as Ranchi and Lohardaga. The data used in this study was generated by the Sentinel 2A satellite from ESA Copernicus and altered using SNAP 9.0 in the mentioned regions. In this context, spectral signatures of lateritic bauxite specimens were examined on GIS software using the spectral characteristics of lateritic bauxite. In this spectral signatures and central resolution of Sentinel 2A was preferred and was made use of which vegetative spectral signatures were visible i.e. VNIR-SWIR (visible-near-infrared and short wave infrared) domain. Understanding the distinctions between the spectral characteristics of bauxites and laterites is made easier by analysing the spectral signatures of lateritic bauxite samples. Based on these variations, simple pixel values of pictures were used after applying formulation in SNAP 9.0 After uploading the image in SNAP 9.0, the image was further underwent operations and later output was generated in the form of band 11 and band 12 image. The SNAP 9.0 mapping method is used to map the presence of bauxite deposits along the research region, and the occurrence is draped over the DEM of the study area. The pictorial representation of availability of bauxite suggests the size of the bauxite mineral resources. The statistical program SPSS was used to assess the data, and it was found that the statistically significant difference between the two indices was 0.005 which follows (p≤0.05) with a 95% Confidence interval. The standard error difference is around 0.1555, whereas the average mean difference is almost 1.20311. The area of Research study Ranchi and Lohardaga of Jharkhand displays a distinct bauxite resource zone, according to a research that was conducted utilising data and the aforementioned approach with suitable regard for the results generated. Consequently, SNAP 9.0 used Sentinel 2A from ESA Copernicus data to identify bauxite.
