Is there a way to convert ECEF to Lat Long with EagerLoading off without changing the global settings?

[graves-k]

Is your feature request related to a problem? Please describe.

I want to convert an ECEF to a Lat, Long Coordinate with Eager Loading Off without overriding the Global Settings.

Describe the solution you'd like

I'm currently using this code to do the conversion, however the static ECEFToLatLong method uses the GlobalSettings.Default_EagerLoad when constructing the Coordinate.

Coordinate c = ECEF.ECEFToLatLong(1333.97, -4653.936, 4138.431);

I'd like a way to pass in the EagerLoad settings I want to use in the ECEFToLatLong method.

Coordinate c = ECEF.ECEFToLatLong(1333.97, -4653.936, 4138.431, new EagerLoad(false));

Describe alternatives you've considered

Something like this would allow the user to optionally specify the EagerLoad settings to use when converting ECEF to Lat Long

  public static Coordinate ECEFToLatLong(double x, double y, double z, EagerLoad? eagerLoad = null)
  {
    ECEF ecef = new ECEF(x, y, z);
    double[] latLong = ecef.ECEF_To_LatLong(x, y, z);
    ecef.geodetic_height = new Distance(latLong[2]);
    return new Coordinate(latLong[0], latLong[1], eagerLoad ?? GlobalSettings.Default_EagerLoad)
    {
      ECEF = ecef
    };
  }

Thanks for bringing this up. I agree there should be more ECEF overloads for this, as this can create huge bottlenecks. I'll add with next release.

In the meantime you have a couple work arounds.

Parse the ECEF Instead

//Specifies input is in ECEF if X, Y, Z coordinate parses successfully.
Coordinate c = null;
if(Coordinate.TryParse(ecef.ToString(), CartesianType.ECEF, eagerLoad, out c))
{
    //Follow on Logic
}

Adjust Global Default Settings At App Startup
Best if this is primary behavior. May not work if you need versatility though.

EagerLoad el = new EagerLoad(EagerLoadType.ECEF | EagerLoadType.Celestial);
GlobalSettings.Default_EagerLoad = el;
