It would be much better if after doing a detailed surface scan all the points of interest on the surface show up on the surface map. It's really time consuming to have to orbit the planet to visually determine an optimal location for landing. Being able to see if a geological site is in a relatively flat spot from the map would significantly reduce the time waste involved. I would probably land at more sites on a planet if I didn't have to waste so much time trying to guess which sites I can land at with minimal issues finding suitable terrain or avoiding areas where the SRV will have issues.
