    abstract = {The rapid phase of urbanization and infrastructure development in Krishnagiri distirct has been
observed recently. The unique characteristics of the granite deposits in Krishnagiri and Dharmapuri districts
of Tamil Nadu resulted in making the country a global producer of the granite rocks. This led to intensified
quarrying activities between Dharmapuri and Krishnagiri. However, this surface mining method has a potential
to impact the environment in a negative way causing loss in vegetation, depletion of natural resources increases
the temperature, loss of scenic beauty and contamination of surface water resources. To assess the land cover
changes caused by granite quarrying activities, remotely sensed data in the form of Landsat images between
2000 and 2017 were used. Pattern classification was used to create maps. Accuracy assessment using Google
EarthTM as a reference data yielded an overall accuracy of 88%. The post classification change detection method
was used to value the land cover changes within the granite quarries. Granite quarries increased by 2562.78 ha
while formation of quarry lakes increased to 5.3 ha over the 18 year period. Vegetation cover decreased by
1521 ha in area while 18.3 ha bare land was lost during the same period. This study demonstrated the utility
of remote sensing to detect changes in land cover within granite quarries.}
