Really impressive mapping in this piece

GIS After Dark - YouTube

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!

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.

Discrete and contiguous versions of brown to green, red to yellow to blue, and magenta to blue divergent color palettes.

TIL. Adobe has scientific color palettes in their design system: spectrum.adobe.com/page/color-f...

Map of North American (mostly CONUS) maximum temperature on March 19, 2026, with a palette that goes blue - green - yellow - orange - red from low to high. The hottest temperatures are in the U.S. southwest and northern Mexico, coldest over Hudson Bay. Desert areas in Arizona and California were 110˚ F or even hotter.

Yesterday’s high temperature across the contiguous U.S. It should go without saying, but it’s astonishingly hot for March.

Image of a map from the 1940s of migratory flyways for ducks, geese, and swans in North America

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?

Thank You for the Kind Words - Daniel P. Huffman, somethingaboutmaps YouTube video by NACIS

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.

I mean, I'm guessing it is. I haven't watched it, and October was a long time ago.

These maps of the Iran war are uniformly fantastic, especially the animated ones showing changing flight and shipping patterns. #ddj #cartography

Thank you to everyone who joined our sessions at #FedGIS2026 this week. I really enjoyed making these little maps to demo some of the new software features and enhancements in ArcGIS Pro.
