How many of us know where, with easy availability of 60cm resolution satellite data, it is now important to distinguish between shadows and the objects which cast them - more so for auotmated classification and feature detection in digital imageries. It is very important to detect what is or is not a shadow to correctly identify the elements that appear in it. High-resolution images provided by current satellites and planes have opened a new era in the field of teledetection, and that resolution enhancement also means that shadows, something inherent in any image, take on special significance.
