The article mentions that rows of trees is “the old” way of planting trees and this new technology will enable … what exactly? Obviously they won’t plant in the middle of the road, and I get the benefit of identifying areas that needs trees, but what exactly is different in the way they are placed along the road?

They mentioned “leaf-level” visualization, meaning they have now 3D data to work with instead of a pixel on a map. Practically this means they can simulate time of day coverage, and can plan for tree species for different foliage heights.

look like they have new tool to estimate coverage of tree, and then residents can require government keep the region they want have same coverage.

It looks cooler and generates more meetings, presentations, fluff, costs to involve tech/simulation/AI/etc rather than to just boringly plant trees. Now they've got a TED invitation in it.

  I wish these sorts of studies quantified how much more useful they are than the last model. There's a lot of papers out there where they reproduce some finding from an older method or dataset, but use the new hot method or dataset. Very few of them go ahead and do power comparisons between old and new, to see if it was even worth all the trouble and by how much.

    I found this: https://labs.aap.cornell.edu/daslab/projects/treefolio https://labs.aap.cornell.edu/daslab/projects/treefolio The videos were ok > Tree Folio uses bespoke tools to identify tree canopies from raw LiDAR data. We've built a filtering program to isolate tree canopy points from the rest of the LiDAR data, a clustering algorithm to extract 3D models of each individual tree from the canopy, and a custom shading simulation platform that models shading interactions between the specific tree and the surrounding buildings

      I went through their website, but it didn't really answer my question of if this was really better than some old fashioned way, e.g. taking satellite imagery and measuring density of canopy and using some simple formula to estimate shade effect based on tree or orientation of the street perhaps. 3D modelling, constantly updating LIDAR maps, custom shading simulation, it all seems like a lot of resource heavy technology. I'm not sure whether or not its being applied in a way that actually offers a statistically significant benefit over other, maybe less expensive methods.
