Laxenburg, Austria, 8th September 2014
All spatially explicit data in the
model are harmonized at the
simulation unit level (212 707 in
total)

SIMU = [Country, ALLCOLROW, ALTICLASS, SLOPECLASS, SOILCLASS]
SIMU1 = [Canada, CR100072, Alti1_0, Slp1_0, Soil1_Sandy]
• CR100072: latitude and longitude
• Alti1_0 : altitude between 0 and 300m
• Slp1_0: slope between 0 et 3 degrees,
• Soil1_Sandy: sandy soil

Reference unit to compute crop productivity potentials in EPIC
Flexibility of aggregation => but has to be decided at the very
beginning of the project, before the model is run
Trade-offs between computational time and fine spatial resolution
level
In REDD-PAC, for the Congo Basin and Brazil the spatial resolution
is [Country, ALLCOLROW, AEZCLASS]
>3000 pixels for Brazil
>1550 pixels for the Congo Basin (6 countries)
