Parses latitude from the provided string for the user defined reference ellipsoid, assuming that the DecimalDegrees (DD) format or the DegreesMinutesSecondsDirection (DMS) format is in use.

Parameters

semiMajorAxisAInM

a semi major axis A (in meters) of the user defined reference ellipsoid

inverseFlattening

an inverse flattening of the user defined reference ellipsoid

str

a string to be parsed

precision

a precision used in parsing

latInDeg

the parsed latitude 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 before running parsing. The valid semi major axis A (in meters) is a real number greater than 0. The valid inverse flattening is a real number greater than 0. The valid precision is an integer number in the range from 0 (inclusive) to 15 (inclusive). The function recognizes two formats: DecimalDegrees and DegreesMinutesSecondsDirection (DMS). DecimalDegrees - indicates the decimal degrees format, for example: 38.889139;. DegreesMinutesSecondsDirection - indicates the DMS format or DDD MM SS.SSSS [N, S], for example: 38 53 20.9 N. The function verifies the validity of the parsed result also. The valid latitude is a real number in the range from -MaxLat (exclusive) to MaxLat (exclusive), where MaxLat is the function of the reference ellipsoid.

Example

This sample shows how to call the TM.ParseLatitude method from C# code:

 string errorMessage = String.Empty;
 
 double semiMajorAxisA = 6378137;
 double inverseFlattening = 298.257223563;
 
 string str = "38 53 20.9 N";
 int precision = 10;
 double latInDeg = Double.NaN;

 if (TM.ParseLatitude(semiMajorAxisA, inverseFlattening, str, precision, out latInDeg, out errorMessage))
 {
     Console.WriteLine("LatInDeg: " + latInDeg.ToString());
 }
 else
 {
     Console.WriteLine(errorMessage);
 }
