Good shot Ving. I realise that your question about mountain heights was idle speculation, but there's software called Jim's Lunar Terminator Visualization Tool which I'm told enables you to add heights of mountains, crater walls etc as well as Lat/Long, crater dimensions etc, to your images. Link:

Definitely for the seriously obsessed, but just think - you could add a lot more lovely red squares and lines to your shots! Names, numbers, all sorts of things....
