| Research Abstract |
In this project we have developed an image processing system to automatically produce high-resolution digital elevation models (DEMs) from topographic contour maps, based on our fundamental system that was already made by us. Concretely, testing the system to many real topographic maps, we developed and improved performance of the adopted algorithms that are mainly on contour image processing to effectively extract and process various topographic features from topographic contours and DEMs. And also we have tried implementation of the total system using graphic-user-interface (GUI) techniques to realize a user-friendly one.
