SoilGrids1km is a collection of updatable soil property and class maps of the world at a relatively coarse resolution of 1 km produced using state-of-the-art model-based statistical methods: 3D regression with splines for continuous soil properties and multinomial logistic regression for soil classes.
SoilGrids1km is a global soil data product generated at ISRIC ━ World Soil Information as a result of international collaboration (see list of contributing agencies) and as a proposed contribution to the Global Soil Partnership initiative. SoilGrids1km are outputs of a system for automated global soil mapping developed within the Global Soil Information Facilities framework. This system is intended to facilitate global soil data initiatives and to serve as a bridge between global and local soil mapping. See also: AfSoilGrids250m system.
Important notice: the SoilGrids1km layers are of limited thematic (wide confidence limits) and spatial accuracy and still contain artefacts and missing pixels. Help us improve these maps by submitting a validation report or by contributing georeferenced soil profiles (points) and covariate data (rasters with global coverage at resolutions of 1 km or better). As soon as we receive new ground observations and/or new validation reports, we can re-run the predictions to produce an updated version of SoilGrids. Read more...

GeoTiffs of SoilGrids1km (236 GeoTiffs) can be obtained either via the web-mapping interface at www.soilgrids.org, via FTP, via the REST service and/or via a smartphone App. The tiling service at www.soilgrids.org allows for selective download of (maximum 5 per session!) 10 by 10 degree tiles. Each tile is 1200 by 1200 pixels. To download the complete (global soil mask) images please use the FTP service:
