🛰️ Why this matters: Urban trees improve air quality, reduce heat, and enhance quality of life. But field surveys for tree counting are time-consuming and expensive. Our method combines deep learning and CHM data to map trees across various urban landscapes with >95% accuracy! 💡 #AIforGood #GIScience tandfonline.com/doi/figure/1…

Between 158,000 and 40,000 years ago, a super-eruption dramatically reshaped the landscape of Guatemala, creating Lago de Atitlán. 🌋 #Landsat 8 data were draped over a digital elevation model from NASA’s SRTM to emphasize the area’s terrain. go.nasa.gov/400oNrR
A natural-color Landsat 8 satellite image of Lago de Atitlán created from thousands of years of volcanic activity in Guatemala. White text in this image highlights Río Quiscab, Río Panajachel, Lago de Atitlán, Volcán San Pedro, Santiago Atitlán, Volcán Toliman, Guatemala, and Volcan Atitlán. In the image acquired on January 17, 2024, vegetation appears green, the lake appears dark blue, and bare earth appears tan.

One of the last #AGU24 sessions I caught was "A Vision for What's Next: NASA’s Evolving Data, Software, and Science II," convened by Dr. @ChelleGentemann et al. In it, Dr. @steadyflux delivered a great talk on @NASAEarthData. 👏 It was great to be back at AGU in person! 😉
