Data Quality

Obtained from LandInfo (Sinclair Knight Mertz) 8/12/99 who retained the data from a project previously undertaken by the Australian Surveying and Land Information Group (AUSLIG) for the Territories Office earlier in the decade. Lineage is not known prior to receipt by GA as no metadata was received.

GA converted the DGN files received into ESRI Shapefiles and projected the files to CKIG92. The files were renamed to reflect their content. Some features which were illogical were deleted (eg. Polygon contours, Runway lights labeled as golf tees). In December 2003, GA projected the topography data to UTM(WGS84) Zone 47S.

Positional Accuracy In this GIS system the Cadastre was taken as the reference dataset. For West Island the position of features is accurate. For other islands the position of features is up to 5 metres displaced from the Cadastre. The accuracy of features in the third dimension is questionable (their are spikes in the data that are probably not real).
Attribute Accuracy Height attributes are incomplete. Polygon runway lights were labeled as golf tees. Otherwise attributes appear to be accurate.
Logical Consistency Appears consistent.
Completeness Appears complete.
