🗺 This week, our team is raising awareness about Arctic change at #EsriUC2025 in San Diego. Today, @cmshintani.bsky.social's “Navigating the new Arctic"—co-produced with Sámi partners at the International Centre for Reindeer Husbandry —is featured in the Map Gallery.

Thrilled that our urban tree cover work is leading to meaningful change. We provided 75 cities in NZ with an estimate of their tree cover and just a week later one town is looking at changing their Tree Policy to increase its canopy cover.

Four maps of the flooding in Kerr County, TX. Each newsroom drew on varied data sources & focused on a different aspect of the disaster.

Refined combination of color-coded rainfall data & shaded relief by Laris Karklis, @washingtonpost.com

Map of rainfall and topography for July 4 showing what led to the flooding in Kerr County, Texas. About 12 inches of rain fell on steep hillside that funneled into narrow stream valleys.

Parts of the Mediterranean Sea reached 30C this week, much earlier than usual, raising fears for marine life.

For some areas, this is 6 or 7C warmer than usual at this time of year.

Our story with more maps by @markpoynting.bsky.social and me here:

Map of sea surface temperatures in the Mediterranean Sea showing parts of it reached 30C such as off the coast of Calabria, and the islands of Majorca and Sicily. Below the map is a chart showing daily maximum temperature at a buoy next to Majorca where it reached 30C for the first time this early in the season.

I’m intrigued by this compilation of William Smith’s maps: press.uchicago.edu/ucp/books/bo...

He was instrumental in both the development of geological mapping & the idea of faunal succession:
earthobservatory.nasa.gov/features/Wil...

#cartography #maps 🗺️
Cover of the book STRATA: William Smith’s Geological Maps. It’s predominantly ocean blue with map details on the bound edge and corners. Two-page spread from STRATA: William Smith’s Geological MapsWilliam Smith’s Geological Maps. Composite of Smith’s Geological Map of England and Wales and Part of Scotland—the first geologic map to cover such a large area in such fine detail. The map used hand-applied color gradations to show where one formation gave way to the next, conveying three dimensions of information on a two-dimensional surface.

Let's dive into this a bit. A short and very incomplete thread on US Forest Service research. 1/
dendromecon27.bsky.social Steph is back at work @dendromecon27.bsky.social · May 31
It’s finally in writing. The detailed President’s budget clearly wants to completely eliminate USFS Research
Screenshot of budget with the more important line being above the table of zeroed out 2026 line items: “The Budget does not request new funding for Forest and Rangeland Research: instead the agency will strategically utilize existing carryover balance to responsibly and effectively terminate research programs and close research stations “

The word is out officially, now: SoilTemp has finished its transformation into 'The MEB-network' - a fully-fledged research network that goes far beyond just being a database. And boy, does that make me proud!

Let me show you all the ways you can get involved here:

SoilTemp is now MEB!
Over the past six years, I’ve poured my heart into SoilTemp. What started as a vision for a global soil temperature database quickly grew into something much more: a living, breathing community of …

We’re chuffed to announce the 0.2 release of the GeoArrow specification! We released the first version in September, 2023 and have since worked with the community towards our vision that getting spatial data from one library to another should be fast, easy, and preserve properties like the CRS.

Rhynchites caeruleus. These small, shiny beetles are currently easy to observe. They initially appear black to our eyes, but upon closer inspection, they remind me of liquid metal.

Looking for a fun read to kick off your long weekend?

In this blog Jarrett and Julia work to debunk the "Zarr vs COG" dichotomy in favor of a more collaborative approach - all inspired by discussions at #CNG2025 @cloudnativegeo.org

Check it out: element84.com/software-eng...
Is Zarr the new COG? • Element 84
We discuss the actual differences between Zarr and COG and how each stores the data contained within its files to combat the assumption that there is a discrete choice between the two.

Excited to be the Mountainfilm 2025 mural artist in Telluride! My mural, "Cartographies of Arctic Change" (a massive 26.5' x 36'!), visualizes our Arctic research. It's going up now on Telco Coffee, a wall previously graced by JR, Gregg Deal, Banksy, and more. Come see it in Telluride!

A weevil from the genus Polydrusus. Like many other weevils, it also has the mysterious hole between its compound eyes.

The use of color in scientific visualization is steadily improving, but I still see variants of the rainbow palette more often than I’d like.

For more info, and recommendations on for good color palettes, read my series “Subtleties of Color“:

earthobservatory.nasa.gov/blogs/elegan...
A modified jet color palette that goes from dark blue to cyan, yellow, orange, and red. There is a sharp increase in contrast from green to yellow and yellow to orange. This can lead viewers to think there is a sharp boundary where data moves through the values represented by these colors.
