Correcting a Digital Map Data Base with Scene Analysis Concepts and Methods.
Abstract
The problem of updating maps has always been of considerable interest for cartographers.. With the advent of digital cartography and the supply of aerial imagery in digital form in the near future, the question arises in which way information to update maps may automatically be derived from digital imagery by means of scene analysis. This paper proposes an approach and show how a solid set of methods, modularly designed and based on an image processing language, may serve as a toolkit for experimentation. Examples are given by applying the methods to a multitemporal sequence of digitized metric aerial photos. Originator-supplied keywords: Feature recognition, Map updating, Expert systems.
