FGARA Digital Soil Mapping Output - Microrelief

Microrelief is one of 19 attributes of soils chosen to underpin the land suitability assessment of the Flinders and Gilbert Agricultural Resource Assessment (FGARA) project through the digital soil mapping process (DSM). This raster data (in GeoTIFF format) represents a modelled surface of probability of gilgai that is deeper than 30cm. The values are from 0 being least probable to 1 being most probable. This data is derived from measured site data and environmental covariates. The data is used in assessment of water ponding that effects irrigation efficiency. For this project the areas of >0.7 probability are said to have microrelief.
The attribute data file is named "MicroReliefprobability.tif"
Also included are data reflecting confidence of the main dataset. This file is named "MicroRelief_CI.tif". "CI" represents "confusion index".
The DSM process is described in the technical report: Bartley R, Thomas MF, Clifford D, Phillip S, Brough D, Harms D, Willis R, Gregory L, Glover M, Moodie K, Sugars M, Eyre L, Smith DJ, Hicks W and Petheram C (2013) Land suitability: technical methods. A technical report to the Australian Government for the Flinders and Gilbert Agricultural Resource Assessment (FGARA) project, CSIRO.
This raster data provides improved soil information to identify opportunities and promote detailed investigation for a range of sustainable development options and was created within the “Land Suitability” component of FGARA projects.
