Land use and land cover (LULC) analysis is an essential tool for understanding the spatial distribution of human activity and natural features across a geographical area, supporting resource monitoring and land management decisions. This study presents a LULC analysis of Koppal district, Karnataka, India, using a satellite image acquired on 27 October 2024, processed through ArcGIS and classified using machine learning algorithms. The district was classified into six categories: agriculture, settlements, forest, water bodies, grazing land, and mining areas. Random Forest and Support Vector Machine (SVM) classifiers were applied to the pre-processed Landsat-8 and Sentinel-2 imagery, and the classification was validated through a confusion matrix and Kappa coefficient. The results indicate that agriculture remains the dominant land-use class, though its extent has declined over the past two decades in favour of settlements and mining. The classification achieved an overall accuracy of approximately 86%, with a Kappa coefficient of about 0.83, confirming the reliability of the approach. The findings highlight encroachment of settlements into agricultural land and the growing footprint of mining activity, and they provide a replicable framework for land-use monitoring in semi-arid districts undergoing rapid transformation.
KEYWORDS
This study presents a LULC classification of Koppal district for 2024 using Landsat-8 and Sentinel-2 imagery, Random Forest and SVM classifiers, and ArcGIS-based spatial analysis. Agriculture remains the dominant land-use category at approximately 50% of the district area, but its share has declined steadily since 2000 as settlement and, more significantly, mining activity have expanded, the latter now accounting for over one-fifth of the district. The classification achieved an overall accuracy of about 86% and a Kappa coefficient of approximately 0.83, confirming the reliability of the adopted machine-learning workflow. The results highlight encroachment of settlements into agricultural land, continuing loss of forest and grazing land, and the growing environmental footprint of mining, all of which call for integrated, GIS-supported land-use planning that balances agricultural sustainability, controlled urban growth, and mineral resource development. The methodology developed here — combining multi-sensor satellite imagery, spectral and textural feature extraction, and machine-learning classification within ArcGIS — offers a replicable and scalable framework for LULC monitoring in other semi-arid, agriculture-dependent districts facing similar developmental pressures.
