Geocircle Geocircle Geocircle Geocircle Class

Create a geographic circle object for the given position and radius.

public : Geocircle(BasicGeoposition position, double radius)public Geocircle(BasicGeoposition position, Double radius)Public Sub New(position As BasicGeoposition, radius As Double)// You can use this method in JavaScript.

Remarks

The constructor will throw an exception if the provided BasicGeoposition has a latitude is less than -90 or greater than 90 or if the supplied Radius is outside of the allowed range.

Create a geographic circle object for the given position, radius and altitude reference system.

public : Geocircle(BasicGeoposition position, double radius, AltitudeReferenceSystem altitudeReferenceSystem)public Geocircle(BasicGeoposition position, Double radius, AltitudeReferenceSystem altitudeReferenceSystem)Public Sub New(position As BasicGeoposition, radius As Double, altitudeReferenceSystem As AltitudeReferenceSystem)// You can use this method in JavaScript.

Create a geographic circle object for the given position, radius, altitude reference system, and spatial reference id.

public : Geocircle(BasicGeoposition position, double radius, AltitudeReferenceSystem altitudeReferenceSystem, unsigned int spatialReferenceId)public Geocircle(BasicGeoposition position, Double radius, AltitudeReferenceSystem altitudeReferenceSystem, UInt32 spatialReferenceId)Public Sub New(position As BasicGeoposition, radius As Double, altitudeReferenceSystem As AltitudeReferenceSystem, spatialReferenceId As UInt32)// You can use this method in JavaScript.

The altitude reference system of the geographic circle.

public : AltitudeReferenceSystem AltitudeReferenceSystem { get; }public AltitudeReferenceSystem AltitudeReferenceSystem { get; }Public ReadOnly Property AltitudeReferenceSystem As AltitudeReferenceSystem// You can use this property in JavaScript.

Remarks

Windows supports the Ellipsoid altitude reference system.

The center point of a geographic circle.

public : BasicGeoposition Center { get; }public BasicGeoposition Center { get; }Public ReadOnly Property Center As BasicGeoposition// You can use this property in JavaScript.

The type of geographic shape.

public : GeoshapeType GeoshapeType { get; }public GeoshapeType GeoshapeType { get; }Public ReadOnly Property GeoshapeType As GeoshapeType// You can use this property in JavaScript.

The radius of a geographic circle in meters.

public : double Radius { get; }public double Radius { get; }Public ReadOnly Property Radius As double// You can use this property in JavaScript.

Remarks

The valid range of radius values is from .1 to 10018754.3 meters. 10018754.3 meters is one quarter of the earth’s circumference.

The spatial reference identifier for the geographic circle, corresponding to a spatial reference system based on the specific ellipsoid used for either flat-earth mapping or round-earth mapping.

public : unsigned int SpatialReferenceId { get; }public uint SpatialReferenceId { get; }Public ReadOnly Property SpatialReferenceId As uint// You can use this property in JavaScript.

Remarks

The spatial reference id (SRID) corresponds to a spatial reference system based on the specific ellipsoid used for either flat-earth mapping or round-earth mapping. Spatial instances with the same SRID can be used when performing operations with spatial data methods on your data. The result of any spatial method derived from two spatial data instances is valid only if those instances have the same SRID that is based on the same unit of measurement, datum, and projection used to determine the coordinates of the instances. The most common units of measurement of a SRID are meters or square meters. The default SRID for the Windows platform is 4326 which is WGS84 ellipsoid.

The spatial reference identification system is defined by the European Petroleum Survey Group (EPSG) standard, which is a set of standards developed for cartography, surveying, and geodetic data storage. This standard is owned by the Oil and Gas Producers (OGP) Surveying and Positioning Committee.
