Q: Dynamic segmentation: the routing dataset combined with the line event table generates spatial data. The start and end values of records in the event table connect to each other, covering all values of the whole routing line. But the results of spatial data are missing in half, why?

A: In this case, you can check the nodes of the routing line object to see if there is a single routing value corresponding to the different nodes. The correct routing data requires that every routing value corresponds to a unique node. Because the line data that generated the routing data has the redundant points. You need to make topology processing for the original line dataset before generating the routing data, removing the redundant nodes.
