Data description​

Data in 5 arc minute global geographic raster grids in .zip files with accompanying metadata.

Description of source dataset from Ellis et al. (2010) "Global data for human population density and percentage cover by urban, crop and pasture lands at 5′ resolution were obtained using the updated version of the HYDE 3.1 data model (http://www.pbl.nl/hyde), based on Klein Goldewijk & van Drecht (2006). Global 5′ data for rice cover in 2000 were obtained from Monfreda et al. (2008)."

Data download​

Data can be downloaded directly from the website, I use wget to download from the commandline.

mkdir -p $GISDATA/biomas/Anthromes
cd $GISDATA/biomas/Anthromes
wget --continue http://ecotope.org/files/anthromes/v2/data/input_data/anthromes_2_input_data_ESRI_GRID.zip

Data preparation​

Gdal​

I use gdalwarp to fix geographic limits to 90 (NS) and 180 (EW)

cd $WORKDIR
unzip $GISDATA/biomas/Anthromes/anthromes_2_input_data_ESRI_GRID.zip
for k in cult irrig past rice urban
do
    gdalwarp -te -180 -90 180 90 $WORKDIR/2000/p_${k}/ Anthromes_p_${k}.tif
done
 # alternatively use year in 1700  1800  1900  2000

Grass GIS​

We can create a Grass GIS location from the commandline

grass --text -c Anthromes_p_${k}.tif $GISDB/raw/Anthromes

for k in cult irrig past rice urban
do
    r.in.gdal input=Anthromes_p_${k}.tif output=p_${k}
done

# once imported in grass, we can clean up the downloaded files:
rm -r 1700  1800  1900  2000	methods_smaller.jpg  Readme.txt
rm Anthromes*tif
