Remote Sensing (RS) and Geographic Information Systems (GIS) these technologies are used for various purposes and natural resources. GIS and RS are pixel based and are used as a spatial modeling method to forecast erosion. RUSLE is one of the methods developed to estimate the erosion. RUSLE is the tool used to forecast erosion from five parameters. This study will give you that how much soil erosion happening in Tiruvallur district. By using the Geo informatics techniques, we can be able to find out the soil erosion in an easy way and by using the data like LIS III satellite images and LANDSAT imagery data by using this we can able to predict the soil erosion in Tiruvallur district.
