public interface ILcdAirspaceCorridor
extends ILcdGeoBuffer, ILcdPointList, ILcdGeoPath, ILcdGenericAirspace, ILcdCurve

This interface represents an airspace corridor and provides methods for retrieving its geometry and relationships. An airspace corridor is considered to be a buffer, constructed from a centreline and a width. It has the same aeronautical meaning as a regular airspace, but its geometry better fits specific needs to define airspaces around centrelines like climbing routes, flight paths, etc.

The centreline or axis is represented by a set of ILcdAirspaceSegment objects, of which the last segment needs to be of the leg type ILcdAirspaceSegment.POINT. This segment represents the last point of the axis. Before the contour of the airspace is calculated, the segments are discretized to a point list. The discretized axis points can be retrieved individually through the methods available in ILcdPointList, or as a polyline shape through the method getBaseShape(). The methods of ILcdCurve uses the discretized axis points representation exposed by the methods in ILcdPointList.

The contour of the airspace corridor can be retrieved via getContour(). It is modeled as a complex polygon (i.e., a composite polygon consisting of one or more polygons that each define an edge of the contour). In the simplest form, the contour is represented by a single polygon. In cases where the airspace corridor intersects with itself, multiple polygons are used to define the contour.

The height information of the airspace corridor is stored in features, see ILcdAirspaceFeature and TLcdFeaturedAirspaceCorridor.

Attributes and relationships in AIS domain objects can be required or optional. When unspecified, an attribute or relationship is optional. Note that most optional attributes are modeled using features.
