The original datasets do in general not have the same 26 surface types GEM reads from the geophysical fields. Therefore, mapping tables are used to map a surface type from the original dataset to our 26 surface types. Depending on the dataset the following different mapping tables are used:
CCI CCI-LC: /home/winger/Scripts/GenPhysX/CCI_LC/CCI_LC_lut.csv
USGS USGS : /home/winger/Scripts/GenPhysX/CCI_LC/USGS_GLCC_lut2.csv
NALCMS NALCMS: /home/winger/Scripts/GenPhysX/CCI_LC/NALCMS_lut2.csv
See in the above script example under "# Mapping tables". If you want to modify a mapping table, just take a copy of the existing one, modify it to your liking and then specify its name it in your script instead of the existing one.
