Conducting Final location survey for New line between Shivamogga - Sringeri - Mangaluru (332 km), Talguppa -Honnavara (95 km), Alamtti -Yadgiri (162 km) and Bhadravathi - Chikjajur (73 km).

"Remote sensing studies with limited ground checks consisting of interpretation of satellite collateral and field data for preparation of thematic maps depicting geological units geomorphologic maps depicting Geomorphic units lineament/fracture map showing structural 1 features detailed drainage and surface water bodies, map portrayal of geological and tectonic features and their significance in planning, design and construction of tunnels bridges and Railway formation (Refinement of proposed alignment will be done based on this study wherever required) Note: Only high resolution basic satellite stereo pairs imagery (0.5m resolution) pan chromatic and 4-band multispectral for area of interest will be provided by the client all the processing of the satellite images will be done by the bidder interpretation to be done by an expert in the relevant field. "
