Parses UTM X from the provided string for a reference ellipsoid.

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

utmZone

a UTM zone

utmHemisphere

a preferred UTM hemisphere

str

a string to be parsed

xInM

the parsed UTM X, 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 the parsing result. 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 UTM X is a real number in the range between -MaxX and MaxX. MaxX is the function of the reference ellipsoid, the UTM hemisphere and UTM zone. It takes into account the 40.0 km overlap with the adjacent UTM zones and 0.5 degree overlap with UPS (Univeral Polar Stereographic) projection.

Example

This sample shows how to call the UTM.ParseUtmXInM method from C# code:

 string errorMessage = String.Empty;
 
 double semiMajorAxisA = 6378137;
 double inverseFlattening = 298.257223563;
 
 UtmHemisphere utmHemisphere = UtmHemisphere.Northern;
 UtmZone utmZone = UtmZone.Zone_18_from_78W_to_72W;
 
 string str = "322288.85200403";
 double xInM = Double.NaN;

 if (UTM.ParseUtmXInM(semiMajorAxisA, inverseFlattening, utmZone, utmHemisphere, str, out xInM, out errorMessage))
 {
     Console.WriteLine("X, in m: " + xInM.ToString());
 }
 else
 {
     Console.WriteLine(errorMessage);
 }
