IMeasurementTool Interface

Provides access to members that perform measurements along Geolines between two points.

Description

IMeasurementTool can either be used to calculate the distance and azimuth values of a Geoline based on input start and end points, by utilizing the ConstructByPoints method; or to calculate the end point of a Geoline based on input start point, distance, and azimuth values, by utilizing the ConstructByPointDistAngle method. In either case, the spatial reference of the input IPoints must be specified before they are passed to the particular Construct method. An ISpatialReference must also be defined for the IMeasurementTool::SpecialSpatialReference property, because the results of the Construct methods are dependent on the input spheroid, which is inherent to ISpatialReference. If the SpecialSpatialReference is not defined explicitly, it will default to esriSRGeoCS_WGS1984. The SpecialGeolineType property defines the type of Geoline (geodesic, great circle, or rhumb line) that will be constructed, using the cjmtkSGType enumeration. Note that the SpecialGeolineType property must be set after the Construct method is called.

You can also return an IPolyline representing the Geoline created by the Construct method using the Polyline property on IMeasurementTool. The IPolyline will be densified by the number of vertices specified on the property. This polyline geometry can then be stored in a feature, or displayed as a graphic, or used in any other operation where such a geometry is relevant.
