All files internally compressed using "COMPRESS=DEFLATE" creation option in GDAL. File naming convention:

  • sol = theme: soil,
  • ph.h2o = variable: soil pH in H2O,
  • usda.4c1a2a = determination method: laboratory method code,
  • m = mean value,
  • 250m = spatial resolution / block support: 250 m,
  • b10..10cm = vertical reference: 10 cm depth below surface,
  • 1950..2017 = time reference: period 1950-2017,
  • v0.2 = version number: 0.2,
