空间数据生产是分幅进行的,因此,在实际应用中经常需要将跨图幅的面状或线状要素,合并成同一要素,使其符合现实世界情况。从数据生产与应用的角度,提出了一种DLG数据要素融合算法,并基于.net平台使用C#语言对算法进行了实现。实践证明,该算法对DLG数据要素融合是有效的,且算法处理效率较高。 更多还原

【Abstract】 DLG data is produced by breadth.Therefore,it’s essential to merge polygon or polyline features in different maps according to the real world.This paper proposed a feature fusion algorithm for the data production and application,and also realized the algorithm based on C#.net.The experiment indicated that this algorithm was useful and effective for DLG data features fusion. 更多还原
