Finds UTM zone/s of the specified geodetic coordinate on 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

latInDeg

the latitude (in decimal degrees) of the original Geodetic coordinate

lonInDeg

the longitude (in decimal degrees) of the original Geodetic coordinate

utmZoneList

the list of the UTM zones, 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 input arguments before running the conversion. 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.FindUtmZone method from C# code:

 string errorMessage = String.Empty;
 
 double semiMajorAxisA = 6378137;
 double inverseFlattening = 298.257223563;

 double latInDeg = 38.889139;
 double lonInDeg = -77.049;
 
 List<UtmZone> utmZoneList = new List<UtmZone>();
 
 if (UTM.FindUtmZone(semiMajorAxisAInM, inverseFlattening, latInDeg, lonInDeg, out utmZoneList, out errorMessage))
 {
     Console.WriteLine("Find succeeded.");
 }
 else
 {
     Console.WriteLine("Find failed. " + errorMessage);
 }
