Applications of Remote Sensing in Land Resource Inventory and Mapping

摘要: Comprehensive information on soil resources in terms of type, extent, physical and chemical properties limitations/capabilities is required for optimal management land monitoring changes qualities. The technological advancements the remote sensing have revolutionized resource inventory mapping process. advantage data that it provides synoptic view terrain, which enables to understand relief, use drainage conditions better delineation landform-soil units. Further, digital elevation models (DEMs) facilitated surface parameterization by attributes such as elevation, slope, aspect, flow accumulation, plan profile curvature obtain relief or topography Hyperspectral spectroscopy can be analysed using statistical chemometric techniques derive about wide variety attributes, used mapping.
