Analysis of Urban Sprawl Pattern in Tiruchirappalli City Using Applications of Remote Sensing and GIS

The increase in population as well as migration from rural areas has resulted in drastic land use/land cover changes in the city of Tiruchirappalli. Unfortunately, these changes have not been quantified appropriately. This paper gives an overview of the study done to quantify the spread of urban activity from years 1998 to 2009 along the city using remote sensing/GIS technology. The results showed an unruly 41 % increase in urban activity, with a proportionate decrease in agricultural land during the period of study. An attempt was also made to project the built-up land for the next 20 years based on the available trend of urban changes and rate of population.
