Parses longitude from the provided string, assuming that the DegreesMinutesSecondsDirection (DMS) format is in use.

Parameters

str

a string to be parsed

precision

a precision used in parsing

lonInDeg

the parsed 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 and parsing results. The valid precision is an integer number in the range from 0 (inclusive) to 15 (inclusive). The function recognizes the DegreesMinutesSecondsDirection (DMS) format, i.e. DDD MM SS.SSSS [N, S], for example: 77 2 56.4 W.

Example

This sample shows how to call the Cartesian.ParseLongitudeInDmsd method from C# code:

 string errorMessage = String.Empty;
 
 string str = "77 2 56.4 W";
 int precision = 10;
 double lonInDeg = Double.NaN;

 if (Cartesian.ParseLongitudeInDmsd(str, precision, out lonInDeg, out errorMessage))
 {
     Console.WriteLine("LonInDeg: " + lonInDeg.ToString());
 }
 else
 {
     Console.WriteLine(errorMessage);
 }
