A review on remote sensing and GIS applications in soil resource management

Planning strategies for sustainable land management require solid base line data on natural resources (soils, physiography, climate, vegetation, land use, etc.) and on socio-economic aspects. Extensive and reliable information on soil and land resources are prerequisites for efficient and effective management planning of these vital natural resources. Generation of large-scale spatial database on soil and land resources by conventional method is a time consuming and highly expensive process. The application of Remote sensing technology has been universally recognized as a highly effective and inevitable tool for soil resource mapping and watershed management.
