    Detailed Description

    GeodesicSectorParameters contains:

    • The desired type of output geometry: MultiPoint, Polygon (the default) or Polyline.
    • The center point of the new geometry, which contains a spatial reference.
    • The length of the semi-major and semi-minor axes.
    • The linear unit used for lengths. The default is meter.
    • The direction of the semi-major (longer) axis in angularUnit.
    • The maximum distance between vertices used to construct the sector.
    • The direction of the starting radius in angularUnit. Zero is east.
    • The size of the sector as an angle. The absolute value of this parameter is used. By default, the angular unit is degrees. It should be greater than zero degrees and less than 360 degrees, expressed in angularUnit. The sector angle increases in a clockwise rotation from startDirection.

    When creating a polygon or a polyline, the result may have more than one path, depending on the size of the sector and its position relative to the horizon of the coordinate system. When creating a polygon, the interior of the polygon is the interior of the sector; however, the boundary of the polygon may contain segments from the spatial reference horizon or from the GCS extent. For example, a sector that spans the 180-degree meridian of the WGS-84 coordinate system will have two parts.

    The sector arc and radii are generalized based on maxSegmentLength. The minimum number of points used the construct that arc and radii of the sector is 10.

    When specifying the lengths of the semi-major and semi-minor axes, the larger value is considered to be the semi-major axis length.

    This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.
