Lecture 14 Application of geo information in soil resource studies Land Information System:  GIS based land acquisition management system will provide complete information about the land. Land acquisition managements is being used for the past 3 or 4 years only. It would help in assessment, payments for private land with owner details, tracking of land allotments and possessions identification and timely resolution of land acquisition related issues. Soil Mapping :  Soil mapping provides resource information about an area. It helps in understanding soil suitability for various land use activities. It is essential for preventing environmental deterioration associated with misuse of land. GIS Helps to identify soil types in an area and to delineate soil boundaries. It is used for the identification and classification of soil. Soil map is widely used by the farmers in developed countries to retain soil nutrients and earn maximum yield. Natural Resources Management:  By the hel

Lecture 13 Soil information system for resource management – Tripura as a case study The basic requirement to develop a soil information system (SIS) is to have large datasets. Such datasets are not generally available for all the states and Union Territories of the country. Tripura is one of the states for which relevant and pertinent datasets on natural resources are made available by the National Bureau of Soil Survey & Land Use Planning (NBSS&LUP; ICAR), Nagpur, during the past decade. While reviewing and interpreting the published data on the 1 : 50,000 scale, it was realized that a SIS can be developed which can serve as an example as to how such a system could be built for other States and Union Territories. Tripura was surveyed earlier by the All India Soil and Land Use Survey (AISLUS) and later by NBSS&LUP to develop soil datasets. Since the modern day information system of any natural resource requires its physical location in terms of space, exact refer
