combine_inputs: Combines all inputs into one GAMS gdx file

In michielvandijk/mapspamc: An R package to create crop distribution maps

Combines all inputs into one GAMS gdx file

Description

Combines all inputs, including the harmonized cropland, irrigated area and statistics, and the scores/priors into one GAMS gdx file that can be used by mapspamc as input. If solve_level = 1, a gdx file for each administrative level 1 unit is created.'

Usage

combine_inputs(param)

Arguments

param

Object of type mapspamc_par that bundles all mapspamc parameters, including core model folders, alpha-3 country code, year, spatial resolution, most detailed level at which subnational statistics are available, administrative unit level at which the model is solved and type of model.

Details

The gdx file contains a number of sets and parameter tables that define the model. Sets describe the dimensions of the model, while parameters contain the data along these dimensions. As part of the process to combine all the inputs and if relevant, artificial administrative units are created that represent the combination of all administrative units per crop for which subnational statistics are missing. These units are added to the list of administrative units from the subnational statistics. The names of these units, stored in the adm_area parameter table, start with the name of the lower level administrative unit which nests the units with missing data, followed by ART and the level for which data is missing and ending with the crop for which data is not available.
