I understand that there are many pine trees in Pine Hill, so a drone flying overhead would only see the tops of trees, but that's not how maps work. Cartographers don't draw the tops of trees; they draw what is under the trees. I would like the map to be improved so that it maps the ground underneath the pine trees. The current version of the Pine Hills map isn't serving the function of a map. If you want to keep the pine tree aesthetic, it could start off as a map showing the top of pine trees and switch to showing what's under them after that area of the map has been explored.
On a related note, when I'm inside an anthill, it would be much more useful to see a map of the tunnels that make up the anthill than to see the surface features, which don't help me figure out where I need to go underground. I've played other games that switch to a localized map for each area.
