2025 GDAL User Survey In 2024, the GDAL User Survey solicited feedback to help focus GDAL Sponsorship Program activities. Your contribution mattered. Last years' results triggered the project to embark on the GDAL CLI Mode...

2025 GDAL User Survey is now active for the entire month of December! Visit gdal.org/survey/ & tell the project how you use it, where you get help, what it should do in the future, & how/if it should use LLMs going forward. (optionally) give us your email, we'll even enter you to win a GDAL t-shirt!

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.

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.

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

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.

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.

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.

Beneath the canopy: Pioneering satellite reveals rainforests' hidden worlds - BBC News First groundbreaking images from the Biomass satellite could change our understanding of rainforests

Had an amazing time at #LPS25 this week, where @esaearth.esa.int unveiled the first images from the Biomass satellite.

Read our story with @esmestallard.bsky.social and see the stunning new images for yourself:

This looks impressive. Curious to get to know more details once available.
You also tested this on ALS data with lower point densities?

Composite of Smith’s Geological Map of England and Wales and Part of Scotlandβ€”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.

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 …

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:

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.

Is Zarr the new COG? β€’ 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.

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

Ich habe die Erfahrung gemacht dass dΓΌstere Prognosen zum Klimawandel verdrΓ€ngt werden weil die meisten sich das nicht vorstellen kΓΆnnen und wollen (Wissenschaftler eingeschlossen).

Super dass hier mal eine alte Studie zu den Auswirkungen des Klimawandels gegengecheckt wird. Das passiert selten. Nicht super dass die Prognosen leider auch eintreten.

Wegschauen kann keine LΓΆsung sein Die Buche kΓΆnnte schon Mitte des Jahrhunderts in grossen Teilen der Schweiz verschwunden sein – und kaum jemanden scheint dies zu interessieren.

Der Klimawandel wir die WΓ€lder in der Schweiz stark betreffen - wieso scheint das Interesse bei Politik und Gesellschaft so gering? #Don'tLookUp
