An attempt has been made to demarcate sites for groundwater irrigation quality at upper Manimuktha sub basin, Velar basin, Tamil Nadu through GIS technique using ARC/GIS Software. The irrigation quality standard output was taken to GIS platform. The work was executed with the weighted rating analysis in GIS environment.

The term 'geographic' in GIS refers to the locational attributes which define the spatial positioning of the piece of information on the face of the earth. The advent of digital computers, with high data processing speed and the development of analytical tools in GIS to handle geographically referenced data with ease and flexibility, computer aided GIS has become a reality of late. Using of GIS in hydrogeology is only at its beginning, but there have been successful applications that started to develop. The favourabilty of the irrigational quality was demarcated in GIS. The favourable area occupying in premonsoon was 269 km2 and in the postmonsoon 239 km2.

Abstract


An attempt has been made to demarcate sites for groundwater irrigation quality at upper Manimuktha sub basin, Velar basin, Tamil Nadu through GIS technique using ARC/GIS Software. The irrigation quality standard output was taken to GIS platform. The work was executed with the weighted rating analysis in GIS environment. Spatial and non-spatial data were assessed in a quick and efficient way in GIS. The term 'geographic' in GIS refers to the locational attributes which define the spatial positioning of the piece of information on the face of the earth. The advent of digital computers, with high data processing speed and the development of analytical tools in GIS to handle geographically referenced data with ease and flexibility, computer aided GIS has become a reality of late. Using of GIS in hydrogeology is only at its beginning, but there have been successful applications that started to develop. The favourabilty of the irrigational quality was demarcated in GIS. The favourable area occupying in premonsoon was 269 km2 and in the postmonsoon 239 km2.
