The task involved the formulation of expected outcomes using existing information and the skills and knowledge in each group, a field testing and iteration stage, a building stage and finally the presentation of the model to the group. It was followed by an exercise in using a fuzzy logic approach in applying the models spatially. It was characterised by lively discussion and innovative presentations - and marked by one or two flashes of startling intuition. It was the sort of mind bending process necessary for the only formal evening event of the workshop - the group bonding session. Group Pictionary is won by those with the gall and volume to rise above the common herd and convince the judge that a result had been achieved.
Brain dumps The workshop captured and imprisoned a range of impressive talent.
Established techniques in the use of these tools are not well developed. For example, the software to derive and analyse digital topographic data is continually being revised to remove artefacts and produce a more useful product. A number of those present attended the DEM workshop. The use of gamma radiometrics for soil study is even more in its infancy. The workshop heard of two examples - the insights offered and the limitations differed between sites.
