ArcGIS Pro 3.2 API Reference Guide
ArcGIS.Core.Geometry Namespace / GeometryEngine Class / ConstructGeodeticLineFromDistance Method
The type of geodetic curve to be created.
The from point.
The length of the geodetic line to be created.
The azimuth (in radians) of the geodetic line to be created. Measured clockwise from the north.
The linear unit of the length. Also the linear unit of the densifyParameter if the densifyMode is DensifyByLength. If this is null, the units are assumed to be meters.
The densification mode.
The densification parameter.
Example

In This Topic
    ConstructGeodeticLineFromDistance Method (GeometryEngine)
    In This Topic
    Constructs a geodetic line with the specified length and azimuth.
    Syntax
    Public Function ConstructGeodeticLineFromDistance( _
       ByVal curveType As GeodeticCurveType, _
       ByVal fromPoint As MapPoint, _
       ByVal length As Double, _
       ByVal azimuth As Double, _
       ByVal linearUnit As LinearUnit, _
       ByVal densifyMode As CurveDensifyMethod, _
       ByVal densifyParameter As Double _
    ) As Polyline

    Parameters

    curveType
    The type of geodetic curve to be created.
    fromPoint
    The from point.
    length
    The length of the geodetic line to be created.
    azimuth
    The azimuth (in radians) of the geodetic line to be created. Measured clockwise from the north.
    linearUnit
    The linear unit of the length. Also the linear unit of the densifyParameter if the densifyMode is DensifyByLength. If this is null, the units are assumed to be meters.
    densifyMode
    The densification mode.
    densifyParameter
    The densification parameter.

    Return Value

    Returns the created geodetic line.
    Exceptions
    Remarks
    If the densifyMode is DensifyByLength, then the densifyParameter specifies the maximum segment length.

    If the densifyMode is DensifyByDeviation, then it is the maximum distance from the true geodetic line to the densified output.

    Example
    Construct a geodetic line with specified distance and azimuth
    var sr = SpatialReferenceBuilder.CreateSpatialReference(4326);
    var mapPoint = MapPointBuilderEx.CreateMapPoint(15, 60, sr);
    
    // calculate
    var polylineGeodetic = GeometryEngine.Instance.ConstructGeodeticLineFromDistance(GeodeticCurveType.Loxodrome, mapPoint, 5000000, 45, null, CurveDensifyMethod.ByLength, 300000);
