The Australian Antarctic Data Centre's Casey Station GIS data were originally mapped from Aerial photography (January 4 1994). Refer to the metadata record 'Casey Station GIS Dataset'. Since then various features have been added to these data as structures have been removed, moved or established. Some of these features have been surveyed. These surveys have metadata records from which the report ... describing the survey can be downloaded.
However, other features have been 'eyed in' as more accurate data were not available. The eyeing in has been done based on advice from Australian Antarctic Division staff and using as a guide sources such as an aerial photograph, an Engineering plan, a map or a sketch. GPS data or measurements using a measuring tape may also have been used. The data are included in the data available for download from a Related URL below.
The data are formatted according to the SCAR Feature Catalogue (see Related URL below). Use the Qinfo number of the feature to search for data quality information about the feature: for example, the source of the data.
