We’ve achieved a sky-high milestone! New LiDAR-derived elevation datasets have been updated, covering over a million square kilometres. This area covers 36.6M Canadians – that’s 92% of the population! Learn more: ow.ly/t9so50Q0HYi #OpenData

Soon we won't be able to use nightlights as a proxy for economic growth. Why? It's due to limitations of its spectral bands. Here's the breakdown in simple terms:

The r-lidar development team Université Laval is glad to announce the new lasR package that is complementary to the lidR package github.com/r-lidar/lasR The lasR package is intended to be much more powerful than lidR but also less versatile. It does NOT supersede lidR. #lidR

Early spectral patterns can help identify longer recovery in post-fire forests. My 2nd PHD paper (JUST PUBLISHED & OPEN SOURCE) looks at the patterns of structural recovery after fire in British Columbia using early (<5yrs) of spectral data. 🛰️ …lpublications.onlinelibrary.wiley.com/doi/10.1002/rs…

Happy #EarthRotationDay! As we celebrate this unique day that honors French physicist Léon Foucault, it is also fitting to recognize advancements in #EarthObservation technology. The upcoming #LandsatNext mission will revolutionize our ability to monitor and understand Earth. 🌎
