Progressive Contours Simplification Approach Constrained by Terrain Feature

Abstract:

To maintain terrain details during contour group simplification, a progressive simplification approach is proposed. First, terrain feature points and lines are extracted from contours. Second, both the extracted terrain feature points and lines are taken as constraints and quantified as control variables. At last with the idea of progressive graphics simplification, the non-feature points, feature points, feature lines and their associated curves on contours are selected or deleted progressively to realize dynamic simplification of contours. Experimental results show that this approach can effectively improve the intellectualized degree of contours simplification.
