Introduction: The planned India-based Neutrino Observatory(INO) is a 52 ktons Iron CALorimeter(ICAL) detector [1] to be built at Theni district of Tamilnadu in Southern India. It is designed primarily to study the atmospheric neutrino flavor oscillations through interaction of atmospheric neutrinos in the detector and the main goal of the ICAL detector is to make precise measurement of neutrino oscillation parameters and determine the neutrino mass hierarchy. At a depth of 1.2 Km below the Earth's surface, the INO-ICAL detector will be the biggest magnetized detector to measure cosmic ray muon flux with capability to distinguish μ+ from μ- with large statistics. The average height of the peak around the tunnel region is 1587.32 m and the latitude and longitude at the cavern location are as follows: ? Latitude: 77° 15′0″E - 77° 30′0″E ? Longitude:9°57′30″N - 10°0′0″N
