Soil and Landscape Grid of Australia
Soil Research Special Issue 53(8)Edited by:
The SLGA provides 3D fine spatial resolution soil attribute maps derived from a collation of national site data from all the Australian states and territories and other collections.
In Australia, a wealth of soil data has been collected over the past century. While a national collation of soil mapping exists (the Australian Soil Resource Information System, ASRIS), a lack of national coordination and disparity in these collections has confounded efforts to develop more consistent and comprehensive information on soil in a usable format. + Full description
In 2011, the Terrestrial Ecosystem Research Network (TERN) and CSIRO funded a project to address the above needs. The project (coordinated by CSIRO and working with a broad cross-section of the Australian soil science community) produced the Soil and Landscape Grid of Australia (SLGA), the first continental expression of fine-resolution soil attribute information that adheres to, but also enhances, the specifications of the GlobalSoilMap initiative, which made the case for the soil information needs of the world.
The SLGA provides three-dimensional fine spatial resolution soil attribute maps derived from a collation of national site data from all the Australian states and territories and other collections, new spectroscopic measurements of soil attributes, traditional soil mapping, climatic data, recently derived terrain attributes and data derived from geophysical remote sensing. The maps were derived using new methods for spatial modelling and estimation of uncertainties. In this Special Issue of Soil Research, we present articles that provide background to the SLGA project and on the methodologies used in the various aspects of the project and their results.
The end result of the project is some 11 attributes predicted nationally in six depths to depth of 2 m, with estimates of uncertainty, new landscape descriptors, a mid-infrared spectroscopic database and an online access system to access the data. The maps and data are available free of charge from www.csiro.au/soil-and-landscape-grid and data.csiro.au/dap/search?q=TERN+Soil
The SLGA, described in these Soil Research papers, is the initial version. The intent is for continual improvement using a consistent versioning process. These papers provide the basis for that and will be of interest to a broad readership in the soil sciences.
The workshop was a successful meeting of minds and useful dialog on policy and science but highlighted many gaps in our knowledge and, consequently, the journey ahead for soil scientists and soil policy.
