Abstract

The extraction of linear elements from remotely sensed imagery is a quite complex process. The extraction, for example, of the road network requires also its recognition which is not an easy operation, because road segments are not represented by a constant range of digital numbers in the input images, the shapes of the roads are illdefined, and pixels with the same digital number often represent land cover types which are not related to roads. That happens because in remotely sensed images, certain types of land cover, e.g. buildings, have similar spectral characteristics with roads and, thus, are indistinguishable, at a pre-processing stage, from the roads.
