I’ve always found it confusing that the taxon maps and atlases use different symbology. Is there a reason for this?
For example, here’s part of the Sciurus carolinensis taxon map:
And here’s the atlas:
In the taxon map, places outlined with dotted lines have the establishment means set to introduced (solid lines for unknown, native, or endemic). In the atlas, introduced areas are marked in dark pink, a color very similar to the range polygon. The taxon map indicates whether there are RG observations in an area (green filled) or not (orange filled), while the atlas does not. I also find it strange that at the same zoom level, the atlas has already switched to showing county level presence while the taxon map is still at state level. Finally, the layers are stacked in a different order: in the taxon map it’s places, then range polygon, then observations, while the atlas has range polygon, then observations, then places.
I’m sure someone chose the symbology for a reason, I’m just curious what that reason may have been?
