I recently got lost on a plant station. Could not fined my way back as there were blocked pathways and some sites are huge! You must have a plan of the site for the buildings, so it would be quite easy to and nice to have a MAP come up, saying you are here and can scroll around.
Just like trade data, you could buy a map for a few credits either before you go or in your SVR if you have trouble finding your way. Just a thought.
