AirRouteOperator.AirspaceInput Property
Gets or sets an operator giving airspaces that may be forbidden or have a positive safety factor.
Syntax
public Operator AirspaceInput { get; set; }Property Value
Remarks
The airspace features can be polygons, lines or points that are extruded to top and bottom elevations via AirspaceBottomElevation and AirspaceTopElevation, or they can be volume-encoding rasters from a LineOfSightOperator or an AirspaceCoverageOperator.
By default, an airspace indicates a volume that is forbidden to enter, but it can be passed through if it is given a positive AirspaceSafety factor. Airspaces that are passed through will generate extra output route attributes with names based on the AirspaceName. For details, see the section "Attributes from airspaces" in the operator class page.
Note that an extruded line or point airspace with positive safety will have little effect on the routing, since such an airspace can be passed through quickly without much penalties on the route cost. In fact, a point airspace will have little effect in any case: it will be rasterized to cover a square of three-by-three terrain cells centered on the cell that contains the point, which provides some horizontal clearance around the point, but it is usually better to let an EllipseOperator with a suitable radius generate a polygon airspace instead.
