Title: Coarse Cultural Topographic Datasets (DCW) (National Geoscience Dataset): population centres
CustodianCustodian: Geoscience Australia
DescriptionAbstract: Population centres such as major centres (associated with political DCW dataset (polys) for built up areas), populated places and villages (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 seperate 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 coverages 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 exept 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 comprised of the original DCW populated place point dataset.
Low to moderate accuracy due to highly variable source data and the vintage of this dataset.

Additional metadatapoint items :- feature this items defines the broad feature type that the item falls into UFI a unique feature identifier agso_code an identification number assigned to features of specific types. Only those features that correspond to AGSO_CODE entries have been given an AGSO code. (Geoscience Australia added attribute) desc a description of the feature in terms of its specific AGSO code (Geoscience Australia added attribute) name name of the feature (population centre) type a more specific explanation of what the feature is status this field is not always filled in but where it is it gives and even more specific categorisation to the feature in question
