Converts a longitude in DMS (degrees, minutes, seconds) to decimal degrees.

Parameters

degrees

the degrees part of the longitude in DMS

minutes

the minutes part of the longitude in DMS

seconds

the seconds part of the longitude in DMS

lonDirection

the direction part of the longitude in DMS

lonInDeg

the result longitude in decimal degrees, passed by reference (out)

errorMessage

an error message, passed by reference (out), that contains detailed error / warning information

Return Value

true - the function has succeeded, false - it has failed

Remarks

The function verifies validity of its arguments. The valid degree part is an integer number in the range from 0 (inclusive) to 180 (inclusive). The valid minutes part is an integer number in the range from 0 (inclusive) to 60 (exclusive). The valid seconds part is a real number in the range from 0 (inclusive) to 60 (exclusive).

Example

This sample shows how to call the Geodetic.Longitude.LonInDmsToDeg method from C# code:

 string errorMessage = String.Empty;
 
 LongitudeDirection lonDirection = LongitudeDirection.Western;
 int degreesPart = 34;
 int minutesPart = 45;
 double secondsPart = 56.789;
 double lonInDeg = Double.NaN;

 if (Geodetic.Longitude.LonInDmsToDeg(degrees, minutes, seconds, lonDirection, out lonInDeg, out errorMessage))
 {
     Console.WriteLine("Longitude in degrees: " + lonInDeg.ToString());
 }
 else
 {
     Console.WriteLine(errorMessage);
 }
