Overestimation of LCZ class D (low plants) #927

EmmanuelleKerjouan commented 7 months ago

I'm working on the Montpellier Métropole area. Using GeoClimate, I obtained the LCZ classification with OpenStreetMap data. There's a strong presence of LCZ D, even though we're in an area of scrub. On OSM, these areas are identified as scrub, but are not classified as such (LCZ C: scrub, bush). Coordinates of the study area in 4326 : 43.427595609, 3.531529090, 43.785191822, 4.158179465 Here is the OSM link for the area in question : https://www.openstreetmap.org/way/42257180#map=15/43.5871/3.7282 Here is the result of the classification : Scrub

Thank you for reporting. Indeed, some of the OSM tags have been "recently" added into the GeoClimate input tables. This is a pointed limitation of the current LCZ approach but we definitely have to integrate this point into the next version.
