There are numerous strategies of producing maps of the totally different areas having variations in terrain. Interferometric artificial aperture radar uses the radar method for making maps. Natural mishaps occurring in different parts of the world are monitored by the consultants using the methods of remote sensing and geodesy. The concept is of allowing the waves from the objects and captured by the satellite or from an aircraft.
