The 2024 Annual Crop Inventory map of Manitoba is finished. Note: Class 130 (Too Wet to Seed) is found in the Interlake and Parkland regions of the province. Due to excessive spring rainfall it wasn't possible for farmers to plant crops. #CdnAg #WestCdnAg #CropMap24 open.canada.ca/data/en/data...

The evidence of beavers in the Canadian boreal zone is widespread and often dramatic in satellite images. Our research with Environment and Climate Change Canada is using the 30 m Landsat satellite archive going back to 1985 to derive indicators of beaver activity (i.e., ponding) over large regions.

In cooperation with colleagues from Australia (T. Poblete and P. Zarco-Tejada) and New Zealand (M. Watt), we published a study on comparison between empirical models, scaling-up algorithms, and radiative transfer inversions for chlorophyll content estimation: www.sciencedirect.com/science/arti...

I'm so happy and proud of this decision 🙂. It is very important now to use the data, and compare the performances obtained with 2 and 3 satellites in your future communications. It will be the good way to thank @esa.int and #Copernicus.

If you're using the `lidR` package and looking to expand your point cloud analysis capabilities, the **lidRmetrics** package might be worth exploring. It offers a variety of additional metrics designed to provide a more detailed characterization of forest structure ptompalski.github.io/lidRmetrics/

Hello!. Today in “One day, one paper”, tropical forest clearance impacts biodiversity and function, whereas logging changes structure. Logging affected the environment, but biodiversity and ecosystem functions only showed strong responses to total forest conversion 🌎🍁 www.science.org/doi/10.1126/...
