I heard the phrase "the independent nation of the State of Texas" in an academic talk today and am now trying to think of ways to insert this into all my conversations.

I appreciate the enthusiasm, but the main art work is not mine to share. It appears without attribution and dif text in a few places online. I modified it obviously, but I’m not selling or distributing it for sale. Would appreciate if you removed the t shirt link.

Recently had the chance to do a little GIS analysis for a KQED (NPR) Bay Curious podcast on the Stairways of San Francisco. Should have been a story about the triumph of GIS, ended up being more about the failure of geospatial data 🙃 But it was fun to do anyway!

New poster! Hachure illustrations of the highest Cascade Range volcanoes. This one took a lot of experimentation to get the layout right. If you or someone you know loves this area, check it out. www.etsy.com/listing/4373...
A black and white illustration titled "Cascade Range Volcanoes," showing a 3 by 3 layout of the nine tallest peaks in the range. The art is done in a hachure sketch style. A detail image of the illustration of Mount Rainier A detail image from the poster of Mounts Hood and Jefferson.

Definitely changed the tone/color profile so that could actually count as copyrightable, not for the original content but the artistic expression.

Not just copyright-free stuff, there are several stores that have been selling in-copyright material from the Rumsey collection for many years. His stuff is all over the place. Part of the cost of his open approach I guess. But def supports the thesis that "old maps sell".

Oh I know who Erwin Raisz is! His N Africa map is the first thing I see when I sit down at my desk everyday.

I have to confess something, as a cartographer who has loved maps and map making since childhood... I really don't care for the Tolkien maps as published w his books. They get way too much adoration in our profession 🫣 His personal/working sketches are far more interesting and organic. #cartography

Charlie Kirk was a shitty person with some terrible ideas about the world. He did not deserve to be killed for those ideas, but he certainly doesn't deserve to be re-cast as national hero and role model. He was neither. Source: The Guardian "Charlie Kirk in his own words".

The number of politicians checking shoe boxes and closets for 50th birthday cards and other memorabilia to toss in a fire pit is going through the roof tonight.

Well that ones a bit far fetched, but smell can be mapped, primarily through adjacent information like smell-mentions in geotagged social media or as a direct crowdsourced project. goodcitylife.org/smellymaps/p...

Excellent idea! Both general transit and maybe big rail specifically.

Next maps... Navigable Water Bay Area? Minimum Drive Time Bay Area? Bay Area by Population Density? Bay Area by use of the term "Bay Area" in business name? Bay Area by Snell - how far can you be and still smell the bay? Any other ideas? :P

Map 4: The Visible Bay Area.

Being in the bay area should mean you can at least see bay water, right? This is the Bay Area viewshed. Pixel lightness is related to how much of the bay you can see. Dark areas can't see any bay water!

Map 3: The Minimum Distance Bay Area.

If Santa Cruz Co is not Bay Area, then nothing further away than its closest part (20441 m from south bay water) should be Bay Area. This is the 20441 meter Bay Area buffer.
