Create spam country grid

Creates the spatial grid that is used by SPAM to allocate physical area shares for each crop and system. The border of the country is used as mask to determine the grid and each grid is given a gridID number.

create_grid(param = NULL)

Arguments

param	Object of type spam_par that bundles all SPAM 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

For technical reasons, gridID values are set before the raster is masked with the country border, which means they are unique but non consecutive. Note that grids at a resolution of 30 arcsec can become very large and might make some time to create. The file is saved in /processed_data/maps/grid/

Examples

if (FALSE) {
create_grid(param)
}
