I recently started surface mapping planets to earn some credits. I found out that you can scan (and sell) surface maps even of planets that are not 'unexplored' but actually explored already... So this seemed a good idea and it pays out pretty well.
While selling mappings I have seen a vast range of value for selling seemingly identical data. I mostly focus on Earth-like Worlds and High-metal-Content Worlds, as those are (from what I heard) the most valuable scans. But even here:
I have sold surface mapping scans of Earth-like Worlds from anywhere between 250'000 to 1.5 Million credits. How comes? What makes one scan more valuable than an other? Is there a way to know in advance how valuable a certain scan will be?
Or does the data change value depending on where you sell it?
