I'm thrilled to announce that I will soon be an author! My book, The Twin Cities in 50 Maps, is a cartographic portrait of Minneapolis and St. Paul. The book includes 50 painstakingly designed maps and deeply researched essays that trace the Cities' urbanity, history, ecology, and culture.
Okay, about 4700 labels later I might declare this map done soon. Then again, it surely could cross 5000 if I just take a few years to track down names for every tiny pond etc. 🤔
A few months ago I got to present in the @jhu.edu "GIS After Dark" speaker series, and the recording is now available. Thank you again to Cassie Hansen for inviting me to share the cartographic work happening at Esri! All talks available here: www.youtube.com/playlist?lis... #mapping #cartography

Just found this super-useful tool: cmyk.printingbanana.com I work in CMYK a lot. And sometimes I sample an RGB color from an image as a starting point, and want to find a reasonable CMYK equivalent that *doesn't* use all 4 inks. This tool suggests reduced-ink alternatives.

Two things I love about spring: flowers and the sounds of geese making their way north. I found this cool map from the 1940s in the David Rumsey collection of flyways for ducks, geese, and swans. What are your favorite bird maps? Explore the map: www.davidrumsey.com/luna/servlet...

It occurs to me I never shared the video of my #nacis2025 talk. It's eight minutes of me musing about how to deal with the challenge of accepting praise from colleagues. www.youtube.com/watch?v=1zvt... I mean, I'm guessing it is. I haven't watched it, and October was a long time ago.
