Remote Sensing, Geographical Information System and Precision Farming in India: Opportunities and challenges

摘要

Accurate and timely information is necessary to evolve strategies for sustainable management of natural resources. Today's "Space Age" supported by computer and communication technologies offer great scope for efficient planning and management of agricultural resources on scientific principles. The satellite data hitherto was considered as sensitive and used mostly for defence purposes. However, the space scientists are now willing to share the satellite data, although on a high cost basis, for civilian use. Remote sensing (RS) and geographic information system (GIS) technologies have been of great use to planners in planning for efficient use of natural resources at national, state and district levels. Application of these technologies in the management of natural resources are increasing rapidly due to great strides made in space borne remote sensing satellites in terms of spatial, temporal, spectral and radiometric resolutions. Many of the conventional approaches of handling multi thematic information to arrive at optimal solutions are being computerized using GIS utilities. Precision fanning has been confined to developed countries. Land tenure system smaller farm size (
