摘要

描述了一种将两个数字地图源A和B的几何和属性数据合并成最终地图的方法。这种方法被称为“合并”，它需要识别两个地图上的匹配元素:顶点、弧和区域。合并一般由自动和手动两部分组成。该方法是基于弧链的使用，以确定它们之间的匹配交集。利用弧的属性和几何性质先验地形成了链。这些交点被视为链之间的关系，并存储在一个简单的外部关系数据库中。

Automatic conflation of digital maps

A consolidation method for combining geometrical and attribute data from two digital map sources, A and B, into one, ultimate map is described. This method is called "conflation" and its requires identification of the matching elements on both maps: vertices, arcs, and areas. Conflation generally consists of two parts (automatic and manual). The method is based on the usage of the chains of arcs in order to determine the matching intersections between them. The chains are formed a priori by using both attribute and geometric properties of the arcs. The intersections are treated as relations between chains and are stored in a simple external relational database.
