| GetClosestDownstreamGridPoint(Double, PredicateGridPoint, Boolean) |
Find the specified type of gridpoint which is closest to the given location upstream.
It is assumed that the EngineReach max and min chainages are containing the given chainage, otherwise null is returned. |
| GetClosestDownstreamGridPointT(ILocation) |
Find the specified type of gridpoint which is closest to the given location downstream.
It is assumed that the EngineReach max and mean chainages
are containing the given location (same location ID and
