Makesoil

The makefile.sh script in this archive generates a netCDF map of derived soil properties file at resolutions of 30" (1km) and coarser.

The script uses the 1km SoilGrids rasters of the following soil physical properties:

• sand (mass fraction)
• silt (mass fraction)
• clay (mass fraction)
• organic matter (mass fraction)
• coarse fragments (volume fraction)

The script also uses a 250m raster of WRB soil name from the 2017 SoilGrids data that informs the pedotransfer functions.

The following software is REQUIRED to run the script's programs: cURL GDAL GMT NCO netCDF netCDF-Fortran

The raw soil data could be downloaded in advance, otherwise a data download script is also provided.

Building

Compile the helper programs using make before executing the script.

User settings

specify a directory for the output file, NB this directory has to exist before running the script

example: outdir=../global30minute

specify a target directory where the raw data is stored (or should be downloaded)

example: datadir=/Volumes/Amalanchier/datasets/soils

set the following flag to true if the raw data should be downloaded

getdata=false
