Soil and Landscape Grid of Australia

Essential infrastructure: the right soil and landscape information in the right form

Australia’s soil resources are vital for healthy ecosystems, food production and the economy.

Soil provides the physical base to support plant growth and the cycling of biological resources; it is the source of nutrients and water for agriculture and forestry systems; it supports habitat vital for teeming biodiversity; and it fulfils a complex buffering role against environmental variability. Not all soils are equal, and they vary substantially in their capacity to perform a vast range of ecosystem services.

In the past, Australia's soil information resources did not enable easy access to the rich and diverse data available in different organisations. So, improvements were needed in the integration and delivery of Australian soils information to underpin land management decisions.

To address this challenge TERN has delivered the Soil and Landscape Grid of Australia, which provides easy access to nationally-consistent and comprehensive soil and landscape attribute data at a finer resolution than ever before in Australia. The Grid is an essential piece of national information infrastructure, required to support informed use and management of our soil and landscapes. The Grid delivers a step-change in the way we can view and access the best available information about Australian soils and landscapes for a wide range of applications and users including urban and regional planners, land managers, farming groups, scientists and engineers.

The Soil and Landscape Grid makes the most of significant past investments in soils information by drawing hundreds of millions of dollars' worth of historical data together with new data generated from sampling, laboratory sensing, modelling and remote sensing. It is the result of a significant national collaborative effort bringing together researchers from the CSIRO, the University of Sydney, Geoscience Australia and federal, state and territory government agencies.


Data available

The Soil and Landscape Grid provides data on soil and landscape attributes with estimates of uncertainty. Data are provided at 90m pixels, and are available for six soil depths down to a maximum of 2 metres (0-5cm, 5-15cm, 15-30cm, 30-60cm, 60-100cm, 100-200cm). The data are consistent and comprehensive in easily accessible raster file formats that can be downloaded or viewed through an online portal. Attributes available are:

The Grid is a dynamic product, that can be enhanced and updated as new techniques and data become available over the years. This will ensure that, throughout time, the grid remains a useful and relevant resource for Australian soil information. The Grid is also contributing to global understanding and management of soil and landscapes, through its connection into the Global Soil Map project, in particular the Oceania Node of the project.
