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

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...

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.

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:

Really nice map by @timmeko.bsky.social @postgraphics.bsky.social in this piece about young kayakers traversing the Klamath River now that dams are removed. Read the full story: www.washingtonpost.com/nation/inter...

Just submitted my 'tiny map' entry for the @nacis.bsky.social map gallery! @kartenvergnugen.bsky.social is organizing this amazing idea. 4"x6" maps only! Deadline is Aug. 31 to submit the form, and still have time to make adjustments before #NACIS2025 in October! Form: nacis.org/gallery-regi...

The incredibly kind @johnnelsonmaps.bsky.social made me my very own cartographer stickers! I'll be handing them out in the showcase and after presentations #esriuc2025

This month's Esri #StoryScape features stories and maps celebrating road trips and the great outdoors! Very cool to have my National Park Service map featured. storyscape-esriwhere.hub.arcgis.com/pages/hittin... #StoryMaps #maps #travel #getoutside #outdoors #history

A few weeks ago I starting taking pictures of spring flowers during dog walks, to send to my mom to connect with her and send her some joy each day. Hopefully this brings you a little joy and beauty this morning ❤️

In just ~5 minutes we were able to improve the 1st draft of the map using foundational cartography principles we learned. The 2nd draft could of course be improved further with more time, but the goal was to highlight how just a few minutes of tinkering can really help your map design #FedGIS2025

Decided to map the recent Midwest/Mid-Atlantic snow storm with a color ramp I have been tinkering with. Really cool pattern across the states. Outside is covered in snow here in D.C.! #mapping #cartography

This year I got to participate in Esri's countdown to #GISDay2024, and share a map that inspired me. I selected this map by Amy Tian of the National Parks Conservation Association, mapping the Chesapeake Bay: mapgallery.esri.com/submission-d...
