    7979ORCHIDEE model can read vegetation map based on Olson categories or on PFT categories. When a PFT map is used as an input, the parameter '''land_use''' in the .def file should be set to TRUE, else to FALSE. 
    8080=== Olson map === 
    81 A map at 5km resolution with the dominant Olson class has been generated by Nicolas Viovy based on a 1km IGBP map. The map is available on the common repository of ORCHIDEE drivers on CCRT, IDRIS and other platforms. It is also available [http://dods.ipsl.jussieu.fr/orchidee/SANORCHIDEE/IGCM/INIT/SRF/OL2/carteveg5km.nc, here]. This map contains 94 land categories. The conversion from Olson to PFT categories is done within the code of ORCHIDEE. Up to the version 1.9.5.2, there was a bug when converting Olson category 79 (warm C4 woody savanna). It was distributed into tropical broad-leaved raingreen (40%) and C3 grass (40%) while it should have been tropical broad-leaved raingreen (40%) and '''C4''' grass (40%). This bug has been fixed in the version 1.9.6.

     85==== Based on Olson ==== 
     86A Python script have been developed by Martial Mancip in order to convert 'offline' Olson-based map to PFT-based map. For this purpose, an Olson map has been generated at a 0.5 deg resolution, in which fractions of Olson categories are defined for each cell (and not only the dominant category). The 0.5° Olson map is available [http://dods.ipsl.jussieu.fr/orchidee/SANORCHIDEE/CarteVeg/vegcoor2D_bounds_2_CF_carteveg5km.nc, here]. The PFT map generated by this script is available ?????? here ??????. It contains the same bug than the one reported above for Olson category 79.
