Syntax

public class GeoCircle : GeoMapElement, IGeoMapElement

Constructors

GeoCircle(GeoCoordinate, LinearDistance)

Constructor to initalise the GeoCircle with a centre coordinate and radius

Declaration

public GeoCircle(GeoCoordinate centreCoordinate, LinearDistance radius)

Parameters

Type	Name	Description
GeoCoordinate	centreCoordinate	geographical coordinate of the map icon to be shown
LinearDistance	radius	Radius of the circle

GeoCircle(GeoCoordinate, LinearDistance, LinearDistance)

Constructor to initalise the GeoCircle with a centre coordinate, elevation and radius

Declaration

public GeoCircle(GeoCoordinate centreCoordinate, LinearDistance radius, LinearDistance elevation)

Parameters

Type	Name	Description
GeoCoordinate	centreCoordinate	geographical coordinate of the map icon to be shown
LinearDistance	radius	Radius of the circle
LinearDistance	elevation	Elevation to top of the circle

Fields

ResolutionMaximum

Highest resolution to draw a circle used in AsGeography()

Declaration

public const int ResolutionMaximum = null

Field Value

Type	Description
System.Int32

ResolutionMinimum

Smallest resolution to draw a circle used in AsGeography()

Declaration

public const int ResolutionMinimum = null

Field Value

Type	Description
System.Int32

Remarks

Set to 3 hence a triangle will be drawn

Properties

CentreCoordinate

Geocoordinate centre of the circle

Declaration

public GeoCoordinate CentreCoordinate { get; set; }

Property Value

Type	Description
GeoCoordinate	Centre coordinate of the circle

Elevation

Elevation

Declaration

public LinearDistance Elevation { get; set; }

Property Value

Type	Description
LinearDistance	Elevation above MSL

Radius

Radius (distance from centre to circumference) of circle

Declaration

public LinearDistance Radius { get; set; }

Property Value

Type	Description
LinearDistance	Radius of the circle

Methods

AsGeography(Int32)

Creates a geography type LINESTRING()

Declaration

public string AsGeography(int resolution)

Parameters

Type	Name	Description
System.Int32	resolution	Number of segments that the circle will be constructed

Returns

Type	Description
System.String	String of the geography

Remarks

Will create a LINESTRING of the circle / resolution will be set between 3 and 18

AsGmlPos(GmlDimension)

Creates a value for GML pos element

Declaration

public string AsGmlPos(GmlDimension gmlDimension)

Parameters

Type	Name	Description
GmlDimension	gmlDimension	Controls if 2D or 3D is required for GML pos

Returns

Type	Description
System.String	String of the GML pos element value

AsGmlRadius(LinearDistanceUnits)

Creates a value for GML radius element

Declaration

public string AsGmlRadius(LinearDistanceUnits linearDistanceUnits)

Parameters

Type	Name	Description
LinearDistanceUnits	linearDistanceUnits	Unit of the return radius value in the GML string

Returns

Type	Description
System.String	String of the GML radius element value

Remarks

Always return in meters
