Select boundary box and cell size

Initially you need to import the following package and select the bounding box of the area you are interested in:

BOUNDS="-337500.000 1242500.000 152500.000 527500.000" # Example bounding box (homolosine) for Ghana
CELL_SIZE="250 250"

igh="+proj=igh +lat_0=0 +lon_0=0 +datum=WGS84 +units=m +no_defs" # proj string for Homolosine projection
sg_url="/vsicurl?max_retry=3&retry_delay=1&list_dir=no&url=https://files.isric.org/soilgrids/latest/data"

To a geotiff in Homolosine

This GDAL command will create a local geotiff in the Homolosine projection

gdal_translate -projwin $BOUNDS -projwin_srs "$igh" -tr $CELL_SIZE \
    -co "TILED=YES" -co "COMPRESS=DEFLATE" -co "PREDICTOR=2" -co "BIGTIFF=YES" \
    $sg_url"/ocs/ocs_0-30cm_mean.vrt" \
    "ocs_0-5cm_mean.tif"

To a geotiff in a different projection

The following commands describe a workflow to obtain a VRT or a GeoTiff for an area of interest in a projection of your choice. In this example we will use EPSG=4326

To local VRT in homolosine (directly from the webdav connection)

The first step is to obtain a VRT for the area of interest in the Homolosine projection. We suggest to use VRT for the intermediate steps to save space and computation times.

gdal_translate -of VRT -projwin $BOUNDS -tr $CELL_SIZE \
    -co "TILED=YES" -co "COMPRESS=DEFLATE" -co "PREDICTOR=2" -co "BIGTIFF=YES" \
    "/vsicurl?max_retry=3&retry_delay=1&list_dir=no&url=https://files.isric.org/soilgrids/latest/data/ocs/ocs_0-30cm_mean.vrt" \
    "ocs_0-5cm_mean.vrt"

To a VRT in, for example, LatLong

The following command will generate a VRT in the projection of your choice:

gdalwarp -overwrite -t_srs EPSG:4326 -of VRT "ocs_0-5cm_mean.vrt" "ocs_0-5cm_mean_4326.vrt"

To a final Geotiff

The following command will generate a Geotiff in the projection of your choice for the area of interest defined above

gdal_translate ocs_0-5cm_mean_4326.vrt ocs_0-5cm_mean_4326.tif \
    -co "TILED=YES" -co "COMPRESS=DEFLATE" -co "PREDICTOR=2" -co "BIGTIFF=YES"

To download a global geotiff in Homolosine projection

gdal_translate \
    -co "TILED=YES" -co "COMPRESS=DEFLATE" -co "PREDICTOR=2" -co "BIGTIFF=YES" \
    $sg_url"/ocs/ocs_0-30cm_mean.vrt" \
    "ocs_0-5cm_mean.tif"
