Statement: Regolith-landforms were generated from field observations and interpretation using aerial photographs (1:82 0000 b/w), satellite imagery (Landsat TM) gamma-ray spectrometrics data (90m cell size grids derived from airborne magnetic surveys) and magnetic data (90m cell size grids derived from airborne magnetic surveys). Geological mapping and other geological information obtained from industry, and state/Australian Government bodies are incorporated. Mineral deposit locations and information, where included in particular themes, is largely sourced from the MINLOC database maintained by BRS. Topographic themes have been provided by AUSLIG and DOLA with agreement that public release of any topographic data by AGSO will be in non digital form only. Some amendments to the topographic data have been made by the authors. Lineage of topographic data, prior to receipt from AUSLIG and DOLA, is uncertain. Maps were compiled from unrectified photo overlays onto topographic bases supplied by AUSLIG and DOLA (see notes on topographic data above). Drainage and, where necessary, other topographic features (eg fence lines) were used for spatial control of the regolith-landform data. Compilations were digitally captured either by hand or automatically by scanning and vectorising procedures. Point data with database origins have been located largely by non-differential GPS. Some detail may have been generalised, repositioned, or omitted from the primary data for cartographic purposes.
