Connecting Link

The Road and Path Networks are not topologically structured together. Connecting Links have been introduced to enable a connection between the Road Network and the Path Network without splitting the Road Network. A Connecting Link feature is a linear spatial object which represents a logical connection between the Path Network and the Road Network, and they do represent a feature in the real world. A Connecting Link will always reference a Path Node and a Connecting Node.道路与路径网络在拓扑结构上并未相互结合。为使道路网络与路径网络之间能够实现连接而不分割道路网络，引入了连接链。连接链特性是一种线性空间对象，它代表着路径网络与道路网络之间的逻辑连接，并且它们确实反映了现实世界中的特征。连接链将始终引用路径节点与连接节点。
