Yes, they're both equivalent in that they return position info but the former returns a matrix for you to use in your transform node so that your model will be positioned correctly on the spheroid. I believe the "up" vector of the model will then match the "up" vector at that position on the spheroid so that things are oriented correctly (i.e. a car appears upright sitting on the ground).

Can you clear up me? Thank you!
