Confidence of suitability data for the FGARA project


The Mahalanobis distance is a raster dataset used to report a reliability measure of the prediction of the land suitability data of the FGARA project (Mahalanobis, 1936). The Mahalanobis distance is a generalised distance function that measures how similar samples are based on their covariate information and has been used to assess prediction relia... more

This Mahalanobis reliability data has been created from a range of inputs and processing steps. Below is an overview. For more information refer to the CSIRO FGARA published reports and in particular ‘Land suitability: technical methods. A technical report to the Australian Government for the Flinders and Gilbert Agricultural Resource Assessment’. Broadly, the steps were to: 1. Collate existing data (data related to: climate, topography, soils, natural resources, remotely sensed etc. of various formats; reports, spatial vector, spatial raster etc.) 2. Select additional soil and attribute site data by Latin hypercube statistical sampling method applied across the covariate space 3. Carry out fieldwork to collect additional soil and attribute data and understand geomorphology and landscapes 4. Build models from selected input data and covariate data using predictive learning via rule ensembles in the RuleFit3 software 5. Create Mahalanobis distance (Mahalanobis, 1936)


This work was prepared for the Office of Northern Australia in the Australian Government Department of Infrastructure and Regional Development under the North Queensland Irrigated Agriculture Strategy <http://www.regional.gov.au/regional/ona/nqis.aspx>. The Strategy is a collaborative initiative between the Office of Northern Australia, the Queensland Government and CSIRO. One part of the Strategy is the Flinders and Gilbert Agricultural Resource Assessment, which was led by CSIRO. Important aspects of the Assessment were undertaken by the Queensland Government and TropWATER (James Cook University).

Land suitability assessment


Digital soil attribute layers were used to determine the area of land suitable for irrigated agricultural production in the Flinders and Gilbert catchments of north Queensland. Land suitability is the fitness of a given area for a land utilisation type, commonly expressed as a set of discrete classes numbered from Class 1 (completely suited) to Cl... more
