To evaluate the snow depth for each road, an operator will primarily use the attributes of the road feature, and secondarily the attributes of the feature (if any) from TerrainAccessOperator.PositionInput or TerrainRouteOperator.WaypointsInput, and failing that, the update attributes from the View.

To evaluate the snow depth in terrain, there are no road attributes to consider, so an operator will primarily use the attributes of the feature (if any) from TerrainAccessOperator.PositionInput or TerrainRouteOperator.WaypointsInput, and secondarily the update attributes from the View.

For terrain that is water (ground condition class = 6), the assumed snow depth will have no effect.
