Title: Coarse Cultural Topographic Datasets (DCW) (National Geoscience Dataset): Political areas and Boundaries
CustodianCustodian: Geoscience Australia
DescriptionAbstract: This dataset delineates political areas such as built up areas, land, ocean, pack ice and boundaries such as coastlines, city limits etc. (dataset derived from the Digital Chart of the World (DCW)). For more information on the Digital Chart of the World data please browse the DCW Internet Site http://www.maproom.psu.edu/dcw/. Data can be downloaded from here in vpf format.
NOTE : For more accurate and detailed data covering continental Australia only please obtain the Global Map Data 1M

This dataset was compiled by Geoscience Australia staff from the original Digital Chart of the World VPF format dataset downloaded from the DCW website listed in the abstract. For information on the lineage of the original DCW (VPF format) datasets please view the Digital Chart of the World website listed in the abstract.
The separate DCW tiles NA11, UA11, QC32-33, QD31-33, QE31-33, QF31-33 and all the RC, RD, RE, RF, SC, SD, SE, SF, TC, TD, TE, TF, UC, UD, UE, UF, VC, VD, VE, VF, WC, WD, WE, WF, XC, XD, XE, XF, YC, YD, YE, YF, ZC, ZD, ZE and ZF were compiled into single covers based upon the separate DCW themes. The vegetation layer was not available for the Australian area.
The data was then attributed fully as the existing datasets were attributed in code which only made sense with the DCW Data Dictionary. The field names were changed to be clearer for example the field AEPTVAl was changed to Elevation. No cleaning of the data was necessary except for the place names coverages where upper and mixed case place names existed in the DCW data these were all changed to mixed case.
Geoscience Australia compliant fields were added to the data at this stage: UFI and FEATURE with AGSO_CODE and DESC added to non-polygon themes.
This dataset was compiled from the original DCW political and ocean arc dataset, the political and ocean polygon dataset and the populated place polygon dataset.
Low to moderate accuracy due to highly variable source data and the vintage of this dataset.
