If you’re like me, you use a web map on a near-daily basis for navigation. Maps can be used for more than just navigation though!

By mapping spatial data, you might discover trends that aren’t obvious in a spreadsheet.
My research on Mercury involved generating chemical maps of Mercury’s surface and comparing them to other maps made with data from different instruments on the MESSENGER spacecraft. Here is a poster I made qualitatively describing the process for making geochemical maps of Mercury and what we can learn from them:
