Checks if the provided latitude (in decimal degrees) is valid, i.e. if it can be used in GIS calculations in the Cartesian coordinate system.

Parameters

latInDeg

a latitude (in decimal degrees) to validate

errorMessage

an error message, passed by reference (out), that contains detailed information in case of the invalid latitude

Return Value

true - if the latitude is valid, false - if the latitude is invalid

Remarks

The valid latitude is a real number in the range from -90.0 (inclusive) to 90.0 (inclusive).

Example

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

string errorMessage = String.Empty;
double latInDeg = 38.889139;
            
if (Cartesian.IsValidLatitudeInDeg(latInDeg, out errorMessage))
{
    Console.WriteLine("Latitude is valid.");
}
else
{
    Console.WriteLine(errorMessage);
}
