Geospatial technique refers to a set of methods and technologies used to collect, store, analyze, visualize, and interpret data related to locations on the Earth’s surface. These techniques integrate spatial data with attribute information to understand patterns, relationships, and changes in natural and human systems. In natural resource management, geospatial techniques play a crucial role in informed decision-making, sustainable planning, monitoring resource use, and mitigating environmental degradation by providing accurate, timely, and spatially explicit information. One of the most important geospatial techniques is Remote Sensing. It involves the acquisition of information about the Earth’s surface without direct contact, using satellites, drones, or aerial sensors. Remote sensing is widely used in natural resource management to monitor forests, water bodies, soil conditions, and land use changes. Satellite imagery helps in detecting deforestation, forest degradation, forest fires, and changes in vegetation health through indices such as the Normalized Difference Vegetation Index. In agriculture and land management, remote sensing supports crop assessment, drought monitoring, soil moisture analysis, and estimation of crop yields, thereby aiding sustainable land and water use. Geographic Information System is another key geospatial technique that provides a framework for storing, managing, analyzing, and visualizing
