minDistanceAhead

The minimum length of the horizon ahead for which a horizon snapshot update is triggered. If the distance between the vehicle and the end of the horizon snapshot since the last snapshot update is less than this value, the client will receive a new horizon snapshot. If the explicit distance policy is used for the main path, a value for the minimum distance ahead that is greater than the main path search distance will result in the snapshot being updated on every tick. To trigger update of the horizon snapshot on every tick, regardless of the search distance policy used for the main path, define this parameter to Int.MAX_VALUE in meters.
