Checks if the provided distance is valid, i.e. if it can be used in GIS calculations in the Geodetic coordinate system.

Parameters

distanceInM

a distance to validate

errorMessage

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

Return Value

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

Remarks

The valid distance is a real number greater or equal to zero.

Example

This sample shows how to call the Geodetic.IsValidDistanceInM method from C# code:

string errorMessage = String.Empty;
double distanceInM = 100;
            
if (Geodetic.IsValidDistanceInM(distanceInM, out errorMessage))
{
    Console.WriteLine("Distance is valid.");
}
else
{
    Console.WriteLine(errorMessage);
}
