Abstract
"Cultural landmarks (dataset derived from the DIgital Chart of the World (DCW) Cultural coverage). For more information on the Digital Chart of the World data please browse the DCW Internet Site <a href=""http://www.maproom.psu.edu/dcw/"">http://www.maproom.psu.edu/dcw/</a>. Data can be downloaded from here in <b>vpf format</b>. <p>NOTE : For more accurate and detailed data covering <b>continental Australia only</b> please obtain the <b><a href=""http://www.auslig.gov.au/download/"">Global Map Data 1M</a></b> <p><b>Generic information on DCW datasets :-</b> <br>The primary source for DCW is the US Defense Mapping Agency (DMA) Operational Navigation Chart (ONC) series produced by the United States, Australia, Canada, and the United Kingdom. The ONC's have a scale of 1:1,000,000, where 1 inch equals approximately 16 miles.The charts were designed to meet the needs of pilots and air crews in medium and low altitude en route navigation and to support military operational planning, intelligence briefings, and other needs. Therefore, the selection of ground features is based on the requirement for rapid visual recognition of significant details seen from a low perspective angle. The DCW database was originally published in 1992. Data currency varies from place to place depending on the currency of the ONC charts. Chart currency ranges from the mid 1960's to the early 1990's. Compilation dates for every ONC chart are included in the database."

Lineage
"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. <p>Post-DCW lineage <p>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. <p>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. <p>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. <p>This dataset was compiled from the original DCW cultural landmark arc (miscellaneous cultural features) coverage, the cultural landmark polygon coverage and the utilities arc (powerlines, pipelines etc) coverage."
