.NET wrapper for GeographicLib::RhumbLine.
This class allows .NET applications to access GeographicLib::RhumbLine.
Find a sequence of points on a single rhumb line.
RhumbLine facilitates the determination of a series of points on a single rhumb line. The starting point (lat1, lon1) and the azimuth azi12 are specified in the call to Rhumb::Line which returns a RhumbLine object. RhumbLine.Position returns the location of point 2 a distance s12 along the rhumb line.
There is no public constructor for this class. (Use Rhumb::Line to create an instance.) The Rhumb object used to create a RhumbLine must stay in scope as long as the RhumbLine.

Compute the position of point 2 which is a distance s12 (meters) from point 1. The area is also computed.
- Parameters
-
[in] | s12 | distance between point 1 and point 2 (meters); it can be negative. |
[out] | lat2 | latitude of point 2 (degrees). |
[out] | lon2 | longitude of point 2 (degrees). |
[out] | S12 | area under the rhumb line (meters2). |
The value of lon2 returned is in the range [−180°, 180°).
If s12 is large enough that the rhumb line crosses a pole, the longitude of point 2 is indeterminate (a NaN is returned for lon2 and S12).

Compute the position of point 2 which is a distance s12 (meters) from point 1.
- Parameters
-
[in] | s12 | distance between point 1 and point 2 (meters); it can be negative. |
[out] | lat2 | latitude of point 2 (degrees). |
[out] | lon2 | longitude of point 2 (degrees). |
The values of lon2 and azi2 returned are in the range [−180°, 180°).
If s12 is large enough that the rhumb line crosses a pole, the longitude of point 2 is indeterminate (a NaN is returned for lon2).

The general position routine. RhumbLine::Position is defined in term so this function.
- Parameters
-
[in] | s12 | distance between point 1 and point 2 (meters); it can be negative. |
[in] | outmask | a bitor'ed combination of RhumbLine::mask values specifying which of the following parameters should be set. |
[out] | lat2 | latitude of point 2 (degrees). |
[out] | lon2 | longitude of point 2 (degrees). |
[out] | S12 | area under the rhumb line (meters2). |
The RhumbLine::mask values possible for outmask are
With the LONG_UNROLL bit set, the quantity lon2 − lon1 indicates how many times and in what sense the rhumb line encircles the ellipsoid.
If s12 is large enough that the rhumb line crosses a pole, the longitude of point 2 is indeterminate (a NaN is returned for lon2 and S12).
◆ Latitude
double NETGeographicLib::RhumbLine::Latitude |
|
get |
- Returns
- the latitude of point 1 (degrees).

◆ EquatorialRadius
double NETGeographicLib::RhumbLine::EquatorialRadius |
|
get |
