Applications of Remote Sensing in Civil Engineering 1) Silting of storage reservoirs harbors etc. – Remote sensing technique that makes use of satellite imagery gives idea about the silting of reservoir qualitatively and to some extent quantitatively. 2) Location of Percolation Tanks – The exact location of percolation tanks can be carried out with the help of remote sensing technique, keeping in view that the site required for location of percolation tanks should be on permeable foundations. 3) Revision of existing topo sheets - The rapid revision and updating of existing topo (graphical) sheets can be carried out speedily with the help of aerial photography and satellite imagery. 4) Alignment of new highways and rail routes – The location of most economical alternative sites for such works can very well be carried out speedily by making use of aerial photographs and satellite imagery. 5) Location of Bridge site: The existing foundation condition along the proposed bridge construction site can be ascertained with the help of aerial photographs and or satellite imagery. 6) Location of Dam sites: For gravity, geological investigations of the existing rock in and around the proposed dam site can be carried out by aerial photographs and or satellite imagery. Geological features such folds, faults, dykes, fractures etc. can be determined by the remote sensing technique. 7) Tunneling: Remote sensing i.e. aerial photography and or satellite imagery of the area helps in furnishing all such information and thus ensures the safety of tunnel during its construction stages. 8) Seepage losses in canals: Monitoring of soil moisture in and around the canal system can be possible by remote sensing technique i.e. by careful study of aerial photographs and satellite imagery of such areas.
