Soil/Landform Mapping

A Land Resource Assessment of the Glenelg-Hopkins Region


The purpose of this study was to guide future agricultural development across the Glenelg Hopkins region. This has necessitated the production of soil and landform information at a scale of 1:100 000. The detail available in current datasets is adequate for this scale but it is not sufficient to provide landscape analysis at finer scales. The results of this study should not therefore be used to plan land use strategies at more detailed scales (1:25 000 and larger) unless additional soil and land survey is implemented. This would involve enhancing the map line work and subdividing the map units that are presented here.


This study has combined survey work carried out in 1999-2001 with previously available older survey information, to determine soil-landform units at 1:100 000 scale for the Glenelg-Hopkins region. These soil-landform units are unique for their geology, soil and land forming processes. Units have been further refined to complement the variability in landform characteristics e.g. relief and slope, across these units.
