Explorations in Registration Between DTM and Non-Topographic Features

This paper introduces the concept of polygon overlap on the basis of Aerial Digital Te-rrain Model(DTM), and investigates the conversion between the vector data of variousnon-topographic information acquired from map digitization and the grid type topographicdata offered by DTM. The series of algorithms for intersections and registration are alsopresented. Hence the matching overlap between DTM and non-topographic features is re-alized.
