Lineage
The majority of data in TOPO 2.5M 1998 were derived from Geoscience Australia's GEODATA TOPO 250K Series 1 digital data product. The relevant data was subset from the 1:250 000 scale data and then thinned to an appropriate level for 1:2.5 million scale. Not all attributes have been maintained in translation from 1:250 000 to 1:2.5 million. Revision information from a variety of sources was used to update features to 1998.
