Redistricting—and gerrymandering—is one of the blacker cartographic arts. With the release of data from the 2020 U.S. Census, and the changes in state congressional delegations—some states gain a seat or two, some states lose a seat, others are unchanged—new congressional maps are being drawn up for the 2022 elections. The Washington Post takes a look at proposed congressional district maps in Colorado, Indiana and Oregon, and what their impact may be.

NASA Earth Observatory has had several stories on the western U.S. wildfires, gathered here. This story summarizes the situation; satellite images of the smoke generated by the fires can be seen here, here and here.

Marena Brinkhurst of Mapbox has a comprehensive list of open data sources relating to the wildfires, smoke, and air quality.

Mark Altaweel at GIS Lounge looks at how GIS is being used to map wildfires, smoke and air pollution.

]]> 1789281 Historical Atlas of Washington and Oregon https://www.maproomblog.com/2011/11/historical-atlas-of-washington-and-oregon/ Sun, 27 Nov 2011 21:03:34 +0000 http://www.maproomblog.com/2011/11/historical_atlas_of_washington/ More]]> Last week I received in the mail a review copy of Derek Hayes’s latest book, the Historical Atlas of Washington and Oregon. Now, except for a day trip to Mount Baker in 1993, I haven’t so much as visited either state, so my review is not as informed as a local’s could be. What I can say is that this is the latest in a series of historical atlases by Hayes, whose previous works include historical atlases of North American railroads, California and the U.S. in general, among others. It’s an attractive and reasonably priced hardcover, densely packed with contemporary maps.

On that point: Hayes uses actual, contemporary maps to describe the period. This differs from what I usually expect from historical atlases, which use modern cartography to display historical information. I’m not entirely convinced of Hayes’s method: contemporary maps may not necessarily be accurate; and they’re frequently reproduced at a scale too small to be of any informative use; and the map needed to tell a story may not always be available. But when considered as a thematically and chronologically organized collection of antique maps, it works very well indeed, though I think several subjects, such as the period before European (or as Hayes puts it, “EuroAmerican”) contact, get short shrift.

Still, I cannot emphasize enough the wealth of cartography on display here (Seattle, Tacoma, Portland and the Pacific Northwest rail lines get particularly lavish treatment); this is the sort of thing that would do well as an iPad app or enhanced ebook, where you could zoom in to a full-scale reproduction of all these maps.
