Galenbindunuwewa DS Division, Anuradhapura District
This project focuses on supervised satellite image classification of the Galenbindunuwewa Divisional Secretariat Division using Landsat imagery. The objective was to identify and map major land use and land cover (LULC) classes to support land management, environmental monitoring, and spatial planning.
Galenbindunuwewa DS Division is located in the Anuradhapura District of Sri Lanka’s North Central Province. The area is predominantly agricultural, with extensive paddy cultivation, forest patches, scattered settlements, water bodies, and wetlands that contribute to regional ecological and hydrological systems.
The classification map shows six major land cover classes including water, forest, shrubland, developed areas, wetlands, and planted/cultivated land. Cultivated land, mainly paddy fields, dominates the landscape, while forest areas are concentrated along the eastern boundary.
The accuracy assessment indicates an overall classification accuracy of approximately 76.4% with a Kappa coefficient of 0.577, showing moderate agreement between classified data and reference samples. Water and cultivated land classes achieved the highest accuracy, while shrubland and wetlands showed lower reliability.
This project strengthened practical skills in satellite image classification, land cover interpretation, and accuracy evaluation. The results provide valuable insights for land management and environmental monitoring in the Galenbindunuwewa DS Division.
