Converts the specified geographic coordinate to NAD27 datum in the speciifed NADCON region.

Parameters

latInDegNad83

the latitude (in decimal degrees) of the original coordinate in NAD83 datum

lonInDegNad83

the longitude (in decimal degrees) of the original coordinate in NAD83 datum

nadconRegion

a NADCON region

latInDegNad27

the latitude (in decimal degrees) of the result coordinate in NAD27 datum

lonInDegNad27

the longitude (in decimal degrees) of the result coordinate in NAD27 datum

latShiftInSec

the result latitude shift in arc seconds

lonShiftInSec

the result longitude shift in arc seconds

errorMessage

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

Return Value

true - if the conversion succeeded, false - if it failed

Remarks

The function verifies validity of the input arguments before running the conversion. The valid latitude is a real number in the range from -90.0 (inclusive) to 90.0 (inclusive). The valid longitude is a real number in the range from -180.0 (inclusive) to -180.0 (inclusive). The function returns false, if the original geographic coordinate is outside the specified NADCON region.

Example

This sample shows how to call the ApsNadcon.ConvertToNad27 method from C# code:

 double latInDegNad83 = 45.13;
 double lonInDegNad83 = -120.1313;

 ApsNadconRegion nadconRegion = ApsNadconRegion.ConterminousUS;
 
 double latInDegNad27 = Double.NaN;
 double lonInDegNad27 = Double.NaN;
 double latShiftInSec = Double.NaN;
 double lonShiftInSec = Double.NaN;
 
 string errorMessage = String.Empty;
 
 Console.WriteLine("Lat NAD83: " + latInDegNad83.ToString());
 Console.WriteLine("Lon NAD83: " + lonInDegNad83.ToString());
 
 if (!ApsNadcon.ConvertToNad27(latInDegNad83, lonInDegNad83, nadconRegion, out latInDegNad27, out lonInDegNad27, out latShiftInSec, out lonShiftInSec, out errorMessage))
 {
     Console.WriteLine("Error: " + errorMessage);
 }
 else
 {
     Console.WriteLine("Lat NAD27: " + latInDegNad27.ToString());
     Console.WriteLine("Lon NAD27: " + lonInDegNad27.ToString());
 }
