LCZ classification of Greenhouse horticulture #928

Closed EmmanuelleKerjouan closed 7 months ago

EmmanuelleKerjouan commented 7 months ago

I made an LCZ classification with OpenStreetMap data thanks to GeoClimate, on Montpellier Métropole. In several areas, greenhouses can be seen, identified on OSM as : Greenhouse horticulture. These are buildings with a large footprint, but are identified as LCZ D (low plants). It might be worth classifying these areas as LCZ 8 (large low-rise). Coordinates of the study area : 43.528820713, 3.764570181, 43.661347862, 3.996709717 Here is the OSM link for the area in question : https://www.openstreetmap.org/way/146465892 Here is the result of the classification : greenhouse_horticulture2 greenhouse_horticulture

This is a quite complex question. The greenhouses are indeed large low and low-rise but we cannot really say that they behave as buildings. I think the classification is then really dependent of its dedicated use. I would keep it to what it is, LCZ D but maybe others would have a different opinion. @franetibe @wurtzj

Hi,

Hard to say as there are both buildings and plants... Also depends on the type on greenhouses (heated, glass, etc.) So Yes I'd rather keep them in natural LCZ D for now.
