Class Point

Namespace
NetTopologySuite.Geometries
Assembly
NetTopologySuite.dll

Represents a single point.

A Point is topologically valid if and only if:
  • The coordinate which defines it if any) is a valid coordinate (i.e. does not have an NaN X- or Y-ordinate

Constructors

Point(Coordinate)

Initializes a new instance of the Point class.

public Point(Coordinate coordinate)

Parameters

coordinate Coordinate

The coordinate used for create this Point.

Remarks

For create this Geometry is used a standard GeometryFactory with PrecisionModel == Floating.

Point(CoordinateSequence, GeometryFactory)

Constructs a Point with the given coordinate.

public Point(CoordinateSequence coordinates, GeometryFactory factory)

Parameters

coordinates CoordinateSequence

Contains the single coordinate on which to base this Point, or null to create the empty point.

factory GeometryFactory

Point(double, double)

Initializes a new instance of the Point class.

public Point(double x, double y)

Parameters

x double

The x coordinate.

y double

The y coordinate.

Remarks

For create this Geometry is used a standard GeometryFactory with PrecisionModel set to Floating.

Point(double, double, double)

Initializes a new instance of the Point class.

public Point(double x, double y, double z)

Parameters

x double

The x coordinate.

y double

The y coordinate.

z double

The z coordinate.

Remarks

For create this Geometry is used a standard GeometryFactory with PrecisionModel set to Floating.

Fields

Empty

Represents an empty Point.

public static readonly Point Empty

Field Value

Point

Properties

Boundary

Gets the boundary of this geometry. Zero-dimensional geometries have no boundary by definition, so an empty GeometryCollection is returned.

public override Geometry Boundary { get; }

Property Value

Geometry

BoundaryDimension 

public override Dimension BoundaryDimension { get; }

Property Value

Dimension

Coordinate 

public override Coordinate Coordinate { get; }

Property Value

Coordinate

CoordinateSequence 

public CoordinateSequence CoordinateSequence { get; }

Property Value

CoordinateSequence

Coordinates 

public override Coordinate[] Coordinates { get; }

Property Value

Coordinate[]

Dimension 

public override Dimension Dimension { get; }

Property Value

Dimension

GeometryType

Returns the name of this object's interface.

public override string GeometryType { get; }

Property Value

string

"Point"

IsEmpty 

public override bool IsEmpty { get; }

Property Value

bool

M 

public double M { get; set; }

Property Value

double

NumPoints 

public override int NumPoints { get; }

Property Value

int

OgcGeometryType

Gets the OGC geometry type

public override OgcGeometryType OgcGeometryType { get; }

Property Value

OgcGeometryType

SortIndex

Gets a value to sort the geometry

protected override Geometry.SortIndexValue SortIndex { get; }

Property Value

Geometry.SortIndexValue

Remarks

NOTE:
For JTS v1.17 this property's getter has been renamed to getTypeCode(). In order not to break binary compatibility we did not follow.

Z 

public double Z { get; set; }

Property Value

double
