基于多评价因素的地图要素几何位置调整方法
Elements adjusting algorithm based on multi-evaluation factors
摘要
Abstract
To solve data ambiguity caused by repeatedly collecting the same elements, and to synthesize the influence of elements precision on different source maps, an areal element adjusting algorithm based on multi-evaluation factors is proposed. Three primary evaluation factors are analyzed, whose importance is given by the entropy method. The element reliability is gained by integrating the three factors. And the same point pairs of same linear elements and areal elements can be identified with Frechet distance. The adjusted position is obtained with a weighted average algorithm. Some same elements from a sea chart and a topographic map are utilized to test the proposed algorithm. The result shows that it can improve the quality of areal element adjusting.关键词
