Determining what biome a map is considered on the atlas

I just picked the atlas tree node "Local Knowledge" which gives drop increases for certain items based on the biome (forest, desert, grass, etc...).

I think I'm supposed to look at the graphics on the atlas (or maybe just know what each map corresponds to which biome?) but at this point it's really unclear because it seems like 4 connected maps can easily be a different biome.

It would be extremely helpful to be able to alt-hover over a map and see definitively what biome it is considered to be a part of. Thanks!

yah should just be a affix for the map so we definetly know what biome they are placed on. i mean the node is the only thing that actually goes into the biomes toppic so far. would be great to have a detailed alt info for it, like everything else has.
