Online published on 2 September, 2019. Abstract Techniques for large scale mapping of natural resources is region specific. The technique of large-scale soil mapping using remote sensing data in basaltic terrain of Peninsular Region. The data used for the study are toposheet of Survey of India (1: 50 000 scale); cadastral map of the Pata Meghpar village (1: 4000 scale); and IRS P6 LISS-IV digital data of August (kharif season) and December (rabi season) 2012. Images were interpreted visually and ground truths were collected manually and prepared landscape ecological units (LEUs) map which was used for conducting soil survey and generation of soil map. The LEU units explained a three-tier approach comprising land form, slope and land use characteristics of each parcel of land. Soils occurring in different LEU units were examined and a LEU-soil relationship was developed. The soil map depicting phases of soil series was prepared using ArcGIS 10.0 software.
