ArcGIS Pro 3.4 API Reference Guide
ArcGIS.Core.Geometry Namespace / GeometryEngine Class / ConstructGeodeticLineFromPoints Method
The type of geodetic curve to be created.
The from point.
The to point.
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 Version

ConstructGeodeticLineFromPoints Method (GeometryEngine)
Constructs a geodetic line connecting the specified points.
Syntax

Parameters

curveType
The type of geodetic curve to be created.
fromPoint
The from point.
toPoint
The to point.
linearUnit
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 connecting points
var sr = SpatialReferenceBuilder.CreateSpatialReference(4326);

var pt1 = MapPointBuilderEx.CreateMapPoint(60, 180, sr);
var pt2 = MapPointBuilderEx.CreateMapPoint(60, 0, sr);

// densify by length
var gl = GeometryEngine.Instance.ConstructGeodeticLineFromPoints(GeodeticCurveType.Geodesic, pt1, pt2, null, CurveDensifyMethod.ByLength, -3.356);

// densify by deviation
gl = GeometryEngine.Instance.ConstructGeodeticLineFromPoints(GeodeticCurveType.Geodesic, pt1, pt2, null, CurveDensifyMethod.ByDeviation, -0.0026);
