Honestly, I'm not the typical explorer. I mostly travel to already known places. However, the surface scanner thingy, apart from being useless in VR, only changes the planet from it's natural colors to teal'ish, which isn't really worth the hassle, if you ask meSee, though, this is exactly where a heat map would be most useful. The "hotter the colour", the denser and more active the geological site. Cooler colours would mean at most a handful of largely inactive vents (still great for harvesting mats when they get around to fixing that part of the game), whereas hotter colours means a denser and more active field. Much better than the current "binary" approach IMO.
I think it's one of the most obvious thingies put in the game to simulate something, but in reality being just unrealistically stupid. It's kind of like the SCA. 1300 years into the future it works much worse than adaptive cruise control on a car "back" in 2021. The Galaxy Map as another example of how a GPS turned into something worse.
On the other hand, I remember the days when you could sqeeze a full operating system onto a 170 KB floppy disk, so maybe it's just a reflection of reality.
