The history of soilgrids - The tale so far...

Providing free access to soil data accross borders

ISRIC - World Soil Information


Tom and Jorge work @ ISRIC

Milan and Alex work @ GILAB

We have multiple providers of points

How are soils created?

Covariates / Layers that explain soil formation?


Ecological/Climatic zones

World Geological Map

Other soil maps

All pray to the happy-golden triangle !!!!

  • 3D dataset - Remember that soils have different properties according to depth

  • Full dataset (so far):
    • 9 parameters (e.g: pH, Org. carbon, texture)
    • 3 levels of value confidence (lower, median, upper)
    • 6 depth intervals (figure leftt)
    • 2 soil class taxonomies (WRB and USDA)
    • (each class with its own distribution map)

  • No compression: 270 gigas
  • GeoTIFF deflate compress: 25 gigas

Methodology et al.

Cool!!! Where can I get the files??

XML metadata, metadata tag inside geotiff
what TAXGWRB means ??? Check the metadata!!!

Point query, view and tile download

Point Query??? attributes=ORCDRC,CEC& confidence=M&depths=sd1

{"type": "Feature","geometry": {"type": "Point","coordinates": [-9.417,38.768]},"crs": {"type": "name","properties": {"name": "urn:ogc:def:crs:OGC:1.3:CRS84"}},"timestamp": "1432038701.1","raw": true,"properties": {"soilmask": "soil","ORCDRC": {"M":{"sd1": 56}},"CEC": { "M": { "sd1": 15},"publication_date": "2014-04-02"}}

  • REST Queries (top) return GeoJSONS (right)or GeoTiff tiles

  • From June 2014 till May 2015: 200 000 requests (172,850 queries)


More data,more experience...

16x more data and new attributes

New methodology

Asks a question of a data item and sends either left or right branching off into different nodes

Africa at 250mt resolution

More attribuites like FAO drainage classes

Aluminium Concentration

Total Nitrogen
