Fundamentals of Remote Sensing

4.2 Did You Know?

"...What will they think of next ?!..."

Remote sensing (image interpretation) has been used for archeological investigations. Sometimes the 'impression' that a buried artifact, such as an ancient fort foundation, leaves on the surface, can be detected and identified. That surface impression is typically very subtle, so it helps to know the general area to be searched and the nature of the feature being sought. It is also useful if the surface has not been disturbed much by human activities.
