From the annual maps we summarized the distribution and dynamics of the dominant tree species from 1984 to 2022 in Canada’s forested ecosystems as well as at the ecozone level and with focus on fire and harvest disturbances.

You have probably seen that last week, Benjamin Herfort et al. published an article on the uneven distribution of building data in #OSM in @NatureComms 🎉
👀But did you know that you can easily access completeness data for 13.189 cities in #ohsomeHeX?

Landsat's 51st anniversary approaches.🎂
Not as catchy as #Landsat50, but another year of enhanced observation continuity!
Past year notable with acquisitions from #Landsat 8 & 9 plus accelerated development of #LandsatNext, higher res, superspectral, 3 satellite constellation!
Marking the 50th anniversary of the @USGS / @NASA Landsat Program! 🎉
📢Now out! Landsat Science Team review of impacts and achievements enabled by 50 years of #Landsat observations.

🚨Generative AI has a serious problem with bias🚨
Over months of reporting, @dinabass and I looked at thousands of images from @StableDiffusion and found that text-to-image AI takes gender and racial stereotypes to extremes worse than in the real world.
