Our multidecadal annual time series of dominant tree species layers for Canada are now available on the #GEE Community Catalog! 🛰️🌲🌳🗺️🇨🇦

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.

Time series tree species maps for Canada’s forested ecosystems from 1984 to 2022 at 30 m spatial resolution using #Landsat imagery, topographic and climate data, and cal/val data from Canada’s NFI.
37 species, 39 years, 650 Mha!

@nesbittios @umanitoba @cityofwinnipeg @ManitobaGIS Thank you Lorien. Hope we will collaborate again in the near future 🌲🌳🌎

In this (our first!) open data release, we are sharing over 1.4m GIS-ready canopy shapes for the City of Winnipeg. Each shape contains canopy height, crown area, and canopy density.

@AgathaCzekajlo @umanitoba @cityofwinnipeg @ManitobaGIS 🙏 indeed! Age + species are tricky for the LoD needed in city models. Do you have any recommended lit on this data gap?

I also wonder when people visit cities or new parks how often they say things like “look at those large trees” or “look at these old oaks”

T-4 days!

Srilalitha Gopalakrishnan (Dr) from the Future Cities Laboratory Global, Singapore-ETH Centre will join us later this month to talk about #density, #greenness, #landscapearchitecture, and #biophilicdesign.

@fortiain @bradneuberg @arjenvrielink @Meta @WorldResources @EarthBlox @planet I agree with one of the pros you listed in the review. It seems to me (at least visually) a decent tree mask layer. I used it yesterday to filter my tree top (ALS-derived) data. For the actual tree height, point cloud remains my top choice. But again, not everywhere has ALS data.

[Yuhao Bean Lu @yuhao_bean]

@h_nilforoshan @Nature thank you makes sense now.

A lot of our international students have had to go through these steps!

Thanks to @SmithTripp21, @leannastack and @dr_spoon for putting this together!
