Remote sensing is the science and art of acquiring information about the earth’s surface without being in contact with it. Geological investigation today is being greatly assisted by the application of remote sensing in all aspect of geosciences such as: lithologic mapping, structural geology, geomorphology, glacial geology, mineral exploration, environmental geology, hydrogeology, geobotany, meteorology and engineering geology. The use of remote sensing in geological studies has been found very effective as it is cost effective, saves time, covers large areas and reduces risk of project failure when compared to other traditional mapping techniques. Remote sensing offers geologists the opportunity to provide information in a way that can be easily understood by non geologist. It makes the dissemination of geosciences information readily available especially in rugged terrain where accessibility is difficulty. Although, remote sensing will never replace traditional field explorative geological mapping, it has provided geologists with valuable techniques for improving the traditional mapping process. We can be sure that the future of geological mapping will rely heavily on such remote imaging systems as it is inevitable in the mapping rugged terrain where accessibility is difficult.
