Hey Gary, My experience with this is that you do need to pad out the latlong image before doing the spherical transform. Another option would be to do a custom STmap setup. If you look at the internals of my EnvConvolve gizmo you can see how I manually recreated the maths for latlong projection based on spherical coordinates, which is part of the setup you would want but you would want.
