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.

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

I really love when color is incorporated into map labels ❤️ great piece by @johnmuyskens.bsky.social @naemas.bsky.social @bennollweather.bsky.social wapo.st/4moaloo

Well this is delightful!

Ian Muehlenhaus and I are exactly a quarter of the way through our AI mapping experiment. We're making maps using nothing but #promptcartography. One map a day for an entire year. Follow along with #365daysofmaps and learn more at mapdesign.icaci.org

If you aren't following "One Minute at a Time" on Instagram, you are missing out! @wrneff.bsky.social creates informational videos on D.C. history that are truly remarkable. His latest video covers the history of the Japanese Lantern on the Tidal Basin: www.instagram.com/p/DWi8Vv3gZJG/

A few weeks ago, ahead of peak bloom of cherry blossoms in Washington, D.C., I wrote up a blog post on how I mapped trees across the city in ArcGIS Pro and Map Viewer: www.esri.com/arcgis-blog/... #cartography #mapping

Yesterday was #WorldWaterDay, and I want to be sure to highlight this powerful Living Atlas resource, with cartography by @emilymeriam.bsky.social Learn more about water risk around the globe: www.esri.com/arcgis-blog/... #mapping #cartography

Yesterday’s high temperature across the contiguous U.S. It should go without saying, but it’s astonishingly hot for March. Data from NOAA’s Unrestricted Mesoscale Analysis www.nco.ncep.noaa.gov/pmb/products...

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...

“This is what I like about mapping — you can exercise your creativity but there’s a lot of technical skill.“ @hannahdormido.bsky.social in her Open Visualization Academy course on mapping with QGIS: openvisualizationacademy.org/courses/cart...

Cherry blossom season is fast approaching in Washington, D.C., with peak bloom projected for late March - early April. To prepare, I made some maps of blossoming trees in the city: www.esri.com/arcgis-blog/... #mapping #cartography

Today’s to do list includes creating a plan to get the word out about @awoodruff.bsky.social’s forthcoming GORGEOUS books of maps. This post is part of this work!

Did you know you can submit maps for consideration to be featured on Maps.com? The team looks for maps that inspire, challenge, educate, reward, dazzle, and provoke across a range of topics and formats. Submit your map(s): www.maps.com/submit-map/

Lots of new stuff in the latest Esri Map Viewer update, including: -Improved label positioning for polygon labels -Symbol offset effect, to help distinguish between overlapping features -Animated symbols For all the updates be sure to check out this blog post: www.esri.com/arcgis-blog/...

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.

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

I put together a list of recent job postings in the mapping and journalism space, please add more as you find them! www.linkedin.com/posts/lauren...

Ready for spring and for cherry blossoms to make an appearance! In the meantime I'll be enjoying these beautiful photographs by @hannahdormido.bsky.social www.instagram.com/p/DKn0mT3Oly... ...and reading about illustrated cherry blossom maps by @moriartymaps.com moriartynaps.org/cherry/

Snow is❗still❗melting here in D.C., so why not check out some maps of that snow storm and learn about re-designing color schemes for color vision deficiencies. www.esri.com/arcgis-blog/... #mapping #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.

Thanks to everyone who came to our mapping sessions at #FedGIS this week, and for all your lovely comments. I know I speak for Nathan and @johnnelsonmaps.bsky.social when I say we're always deeply touched by the feedback we receive. Keep mapping!

Looks like my full series on using color in #dataviz finally made the migration to the new NASA science website: science.nasa.gov/blogs/earth-... If you’re new to visualization, or just want a refresher, it covers the basics of color theory, how to build a palette, plus some tips & tricks.

This week is Esri #FedGIS, & I'll be presenting w/ the amazing Valeria Chavez. Catch us in: ArcGIS Pro: Mapping & Visualization registration.esri.com/flow/esri/26... ArcGIS Pro: What's New registration.esri.com/flow/esri/26... Full list of mapping sessions: registration.esri.com/flow/esri/26...

Don't miss these three if you're at #FedGIS, they're in DC this week to share some cartographic magic! registration.esri.com/flow/esri/26...

A few years ago I made this poster and released it as a free PDF (somethingaboutmaps.wordpress.com/2022/12/19/p...). This week, I learned from a colleague that it has actually been posted in an educational setting!

I was laid off from the Washington Post today, along with hundreds (!!!) of incredible colleagues. If you need a data journalist, chart designer, or wacky-idea-specialist, give me a shout!

The @postguild.bsky.social has organized a layoff fund for employees impacted by layoffs at The Washington Post: www.gofundme.com/f/standing-t...

Going to #FedGIS2026, or thinking about attending? Below are some helpful links to learn about and register for the event: Overview: www.esri.com/en-us/about/... Detailed agenda: registration.esri.com/flow/esri/26... Registration: www.esri.com/en-us/about/... Hope to see you there, Feb. 9-11 🗺️

A lot of snow (and ice) fell across the U.S. over the weekend. I decided to map snow depth totals in the Mid-Atlantic, and experiment with some new color ramps. Here's a blog I wrote last year on mapping snow with SNODAS data: www.esri.com/arcgis-blog/...

I love weather and I love maps. So when there is an incoming snow storm it is interesting for me to see how different news agencies are mapping the event. Here are examples from @nytimes.com @washingtonpost.com @cnn.com. Any others you've seen that work well (or don't)? Links threaded below:

The @nacis.bsky.social mentor program is now accepting sign-ups for mentors and mentees. I have been a mentor for this program twice, and have learned so much from the amazing cartographers I was paired with. Deadline to apply Feb. 17th nacis.org/initiatives/...

I've spent the last few weeks slowly going through #NACIS2025 recordings, looking for inspiration and joy in map-making to get me through a difficult time. This is in no way a comprehensive list, but these cartographers and their presentations really stood out to me in their creative process (1/5)

Hello DMV folks! My colleague is working on a community-driven map of D.C. neighborhoods, if you have some time and know the area, let's draw some neighborhood boundaries! experience.arcgis.com/experience/4...

Zodiac signs were originally based on the stars. But over thousands of years, our view of the stars has shifted. That means, if you account for this shift, your sign might not be what you think. www.nytimes.com/interactive/...

New blog post about maps I made for a presentation with @kennethfield.bsky.social and @johnnelsonmaps.bsky.social at #esriuc2025! We each made three maps with the same dataset to highlight different thematic mapping approaches. Loved presenting with Ken and John! www.esri.com/arcgis-blog/...
