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

Providing free access to soil data accross borders


ISRIC - World Soil Information


Presenter:

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?

DEM

Ecological/Climatic zones

World Geological Map

Other soil maps

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

    Description
  • 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??

ftp://soilgrids:soilgrids@ftp.soilgrids.org

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

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

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