SoilGrids1km tutorial

Course title: SoilGrids tutorial
Course Code: ISRIC-SoilGrids
Subject areas (Curriculum): Global Soil Information Facilities, soil mapping
Duration: 2hrs to half day
Short description:

SoilGrids1km is ISRIC's Global Soil Information System at 1 km resolution. SoilGrids1km contains global spatial predictions for a selection of soil properties: soil organic carbon content, soil pH, texture fractions, bulk density, coarse fragments and cation-exchange capacity, soil organic carbon stock, depth to bedrock, and soil classes (FAO World Reference Base soil groups and USDA Soil Taxonomy suborders). The predictions were produced using an automated mapping system, collectively called "SoilGrids", which is an implementation of model-based geostatistics in the Open Source environment for statistical computing R. SoilGrids1km maps are available for download via http://soilgrids.org under a Creative Commons Non Commercial license. 

Moderators: T. (Tom) Hengl & J. (Jorge) Mendes de Jesus
Target audience: Soil mapping teams, MSc and PhD level students working with soil data and aiming at producing soil property maps according to the international (FAO/GlobalSoilMap.net) specifications.
Requirements: Knowledge requirements:
  • Digital soil mapping (advanced)
  • R programming (basic)
  • GIS modelling (basic)
  • GDAL (basic)
