The abstract root class of the geometries hierarchy.
public abstract class Geometry : IGeometry
Properties
Name | Description |
---|---|
CoordinateDimension { get; } | Gets the number of coordinate dimensions for this Geometry . |
abstract Dimension { get; } | Gets the topological dimension of this Geometry . If the dimension is unknown (e.g. for an empty GEOMETRYCOLLECTION) Point is returned. |
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. |
static Null { get; } | Gets an instance of null geometry. |
