Global Soil Information Facilities (GSIF) is an initiative by ISRIC to build open-source tools to collate, harmonize, and provide up-to-date global soil data at high resolution. GSIF aims to serve global land use planning and environmental risk assessment. It is based on key principles of crowd-sourcing data collection, maintaining original ownership of contributed data, using open-source software, following international standards, and making outputs reproducible and publicly accessible. The main users of GSIF will be international agencies, research organizations, and national environmental and soil survey agencies, as well as private individuals and farmers.

scientists.
Ownership by authors --- Data entered to GSIF data portals will remain
property of the original contributors (copyright holders and/or authors).
FOSS --- GSIF is based on Free and Open Source Software (Linux, PHP,
LaTeX, R, GDAL, GRASS, SAGA GIS, PostgreSQL, PostGIS, Python,
Google Earth and similar).
International reference --- Only internationally accepted standards
(International System of Units, international soil classifications systems,
FAO soil field description guides, WGS84, ISO standards) are supported
at the back-end of the system.
Reproducibility --- GSIF is based on automated procedures for mapping,
pattern recognition and report/plots generation. All maps and reports
produced as a part of GSIF are reproducible without human intervention.
Open Access --- All ISRIC-generated soil field records, output maps and
tools used to generate maps will be made publicly available (Open

coordinate systems, scale, uncertainty in the maps) will be either hidden
from the users or communicated using efficient solutions.
GSIF has been inspired by global environmental data initiatives such as
Global Biodiversity Information Facilities, Global Land Cover mapping,
OneGeology and similar. The main practical reason for GSIF is to build cyber-
infrastructure to collate all existing legacy soil data, currently under threat of
being lost forever (!), and add value to such data by using it for mapping and
modeling purposes.
The main users of GSIF will potentially be various international agencies and
initiatives such as GlobalSoilMap.net and other international agricultural
development and research organizations such as FAO, CIAT, USAID, Inter-
American Development Bank, World Bank. We also aim at National
Environmental and Soil Survey agencies, and private entities and individuals,
soil surveyors and soil scientists, but also farmers and agriculture
engineers.

Various GSIF components are being developed by the ISRIC team and
collaborators. The most crucial components of GSIF --- Open Soil Profiles,
Worldgrids, and GSIF R packages will be publicly released by mid 2012.
