Modification of the vegetation input layer (Geoclimate with BD Topo input)

[atoulou]

Hello,

I am trying to use Geoclimate based on BDTopo (v3) input with a modified vegetation layer. I have a more detailed vegetation map for the Lyon Metropolis compared to the one used in BDTopo, and I would like to use this map instead when running Geoclimate.

To achieve this, I replace the "Zone_De_Vegetation" files of the BDTopo folder with the new ones. In the .shp file, I added the columns "ID" and "Nature". I was wondering how the "Nature" column is used in the Geoclimate algorithm. This information is crucial for me to ensure that I correctly fill in the "Nature" column in my layer. Currently, the information I have on my vegetation layer pertains to the size category of the vegetation (I have 5 categories from grass to high trees).

Additionally, do you have any advice on transforming an input layer ?

Thank you in advance.

Best regards,
