A Surface is a two-dimensional geometric object.
public abstract class Surface : Geometry, ISurface
Properties
| Name | Description |
|---|---|
| CoordinateDimension { get; } | Gets the number of coordinate dimensions for this Geometry. |
| Dimension { get; } | Gets the topological dimension of this Geometry. |
| abstract GeometryType { get; } | Gets the type of the geometry. |
| virtual HasCurveGeometry { get; } | Gets a value indicating whether this geometry is or contains curve (not linear) geometry. |
| virtual HasM { get; set; } | Gets a value indicating whether this instance has M coordinate. |
| virtual HasZ { get; set; } | Gets a value indicating whether this instance has Z coordinate. |
| virtual IsEmpty { get; } | Gets a value indicating whether this instance is empty. |
| IsSimple { get; } | Gets a value indicating whether this instance is simple from SFA point of view. |
| IsValid { get; } | Gets a value indicating whether this instance is valid. |
| abstract SpatialReferenceSystem { get; set; } | Gets SpatialReferenceSystem of this instance. This property can be null, is SpatialReferenceSystem is unknown. Assigning new SpatialReferenceSystem will not perform any coordinate transformation, only reference will change. |
