Designer Michael Pecirno experiments with single-subject maps in his project Minimal Maps. No boundaries, just landscape.
The data provided by the USDA is incredible and includes a tremendous wealth of information that makes up the composition of America. By pulling this data and extrapolating specific categories I’ve been able to produce a number of unique and explicit maps that aim to push us away from the ubiquitous and low-resolution (regarding information content) physical and political map.
It still amazes that detailed geographic data like this exists.
