Laxenburg, Austria, 8th September 2014

All spatially explicit data in the

model are harmonized at the

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

Spatial resolution

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)
