Properties

NameDescription
CoordinateDimension { get; }Gets the number of coordinate dimensions for this Geometry.
Count { get; }Gets the number of geometries in this collection.
Dimension { get; }Gets the topological dimension of this Geometry.
override GeometryType { get; }Gets the type of the geometry.
override HasCurveGeometry { get; }Gets a value indicating whether this geometry is or contains curve (not linear) geometry.
override HasM { get; set; }Gets a value indicating whether this instance has M coordinate.
override HasZ { get; set; }Gets a value indicating whether this instance has Z coordinate.
override 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.
Item { get; }Gets a IGeometry at the specified index.
override 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.
