50 States, One Continuous View

This is a map of the United States without insets. Published in 1975 by the U.S. Geological Survey, it shows Alaska, Hawaii and the lower 48 states in the same, continuous view—though Hawaii’s Leeward Islands are cut off (as are the various territories). Can’t have everything, I guess. It’s available from the USGS as a free downloadable PDF; the paper version costs $9. [MapPorn]

In Praise of Inset Maps

The kerfuffle about Shetland being relegated to inset maps (Ed Parsons has taken to calling this “Insetgate”) is not quite done. Kenneth Field shares his thoughts in a post titled “In Praise of Insets,” in which he calls Scottish politician Tavish Scott’s proposal to ban the use of inset maps to portray Shetland as “utter nonsense” and goes on to defend their use more generally.

Insets are not just used to move geographically awkward places. They are commonly used to create larger scale versions of the map for smaller, yet more densely populated places. Often they are positioned over sparsely populated land to use space wisely. I’m guessing Scott would have an objection to an inset that, to his mind, would exaggerate the geographical importance of Glasgow compared to Shetland. Yet … in population terms it’s a place of massively greater importance so one could argue it deserves greater relative visual prominence on the map. Many maps are about people, not geography.
