Dataset Lineage
ANUDEM version 4.6.2 was used to produce a 25 metre floating point grid. Source digital data were contours and drainage (scanned repromats) from AUSLIG 1:100000 mapsheets with a 20 metre contour interval for most areas with some 40 metre contours. Drainage lines were pointed in the direction of flow. A hillshade of the DEM was used to identify errors in source drainage and contour data that were previously missed. The errors, including wrongly directed drainage and wrongly labelled contours were fixed though some errors may remain.
