APPLICATION OF REMOTE SENSING AND GIS FOR IDENTIFICATION AND ASSESSMENT OF CROP GROWTH IN WAZIRABAD COMMAND AREA BY CALCULATION OF IRRIGATION LOSSES AND DEMAND TO IMPROVE THE FARMING

Conference: Third National conference on Agro-Informatics and Precision Agriculture 2012

ABSTRACT

Differentiating the land use and classification of crop precisely using Remote Sensing Satellite images and GIS analysis for calculating the irrigation demand and losses with respect to soil characteristics and topography is an added advantage in utilizing the optimum amount of water distribution to fields. Percolation losses are one of the main losses out of other losses in irrigating the crops. These losses accounts more in the case of course textured soils than finely textured. Integrating and analyzing the multi date satellite imagery and multiple themes using GPS based GIS helps to identify and estimate the crop acreage and assess the crop water requirements and optimum amount of water distribution through canals. Using geographical information systems helps the water resource engineers and managers for estimating the results both in the form of spatial and non-spatial. This paper is a part of research and highlights the advantages of GIS and Remote Sensing in identifying the crop and mapping the canal network in network model, delineating the Command Area in to Blocks/Sub-Blocks and calculating the percolation losses in the fields with a special emphasis on irrigation water management. In this study the parameters like canal network, detailed block boundaries under major to minor canals, crop classified satellite images and soil characteristics of the command area are taken as thematic inputs.
