Present study attempted in Coonoor macro-watershed, Nilgiris District, Tamil Nadu, India where severely affected by landslide during 1978 and 1979. Frequency Ratio (FR) method coupled with geomatic technology is a statistical model to replication environmental conditions. It also uses to take the parameters associated with dependant variables. FR method used for prepare the landslide susceptibility map. Pixel land sliding and non-land sliding calculated in ten factors associated to landslide.
