The study is based on a GIS based analysis methodology where for current data<br />
acquisition, Remote Sensing and Global Positioning System (GPS) were made use of.<br />
The study area selected was Palakkad district of Kerala, located in the realm of tropical<br />
climate lying between 10°21’–11°<strong>14</strong>’N lat. and 76°02’ and 76°54’E long. The various<br />
thematic layers like panchayath boundary, contour, drainage, roads were extracted from<br />
the SOI toposheets. IRS –1D LISS III digital images were used for preparation of the<br />
current landcover and geomorphology of the area. Geological information was derived<br />
from the GSI map. Field and knowledge based multicriteria analysis techniques were<br />
adopted. Fussy based techniques were used to give ranks and weightages to each<br />
individual thematic layer, which in turn was taken into consideration in determining the<br />
ground water potential zones. Drought maps for three different years were prepared and<br />
field verified with depth to ground water level of the area. The three consecutive years<br />
viz. 2008, 2009 and 2010 data was used for the modeling of ground water potential<br />
zone. The final output shows ground water potential map of Palakkad district in four<br />
categories such as Very high / Excellent, High, Moderate and Low. The results can be<br />
used for further investigation and environmental management of ground water.<br />
