Whether your interests are for a small locality or an entire region, it is almost certain there will be information of value when you wish to consider expansion or improvement.

The soil map shown here uses  the Australian Digital Soils Atlas as a basis to provide basic soil types, some of which are more suitable for particular crops..

Base soil data: Bureau of Resource Sciences (1991). Digital Atlas of Australian Soils (ARC/INFO® vector format). [Online] Available HTML: http://www.brs.gov.au/datasets
But we wanted to know about real soil qualities, so we have used technology to value add to the existing data. Here we have used additional BRS data concerning the nutrient levels in surface soils for each of the soil classes shown in the top map. This has been processed to show areas with high to low nutrient levels, allowing us to concentrate on the most suitable areas A1soil map.jpg (43582 bytes)

Additional attributes derived from: Bureau of Rural Sciences (1992). Interpretation of Digital Atlas of Australian Soils mapping units (ARC/INFO® format) Available HTML: http://www.brs.gov.au/datasets
While this 3D map looks like hills and valleys, in fact it shows how surface soil nutrient levels vary! The "hilly" areas have high levels of surface soil nutrient, while the "valley" areas typically are nutrient poor. A1orgdrpimg.gif(131385 bytes)
Here we can see a smaller area in more detail. The basic soil types are shown over a picture image (left), from which all crops of a particular type have been seperated (right). sat_soilclass.jpg (114481 bytes)crops extracted.jpg (35598 bytes)
Using a "hillshade" model (left), we can see how the areas favoured for this crop are concentrated along the river valleys and lower slopes (right). hillshade.jpg (40467 bytes)crops and hilshade.jpg (61569 bytes)

Of course it helps to be able to see areas of interest realtive to a familiar road map. This also helps if we then wish to identify other suitable areas based on their having similar characteristics to the ones we know our crop already thrives on! topo and sat.gif (1325042 bytes)

As a tool for gaining insight and helping make the right choices for crop expansion of diversification, spatial technology has no equal.

If you know your crops needs, MapMakers can find the data and convert it into the information you need.

In this image you can see how existing crops are distributed relative to underlying soil nutrient levels
