The geology of Macquarie Island was mapped between December 1994 and January 1996 in a joint project involving Mineral Resources Tasmania, the Australian Antarctic Foundation and the Australian Antarctic Division.
The geological data has been compiled onto a base map that has been derived from several sources:
- The Spot multispectral satellite mosaic produced by the Australian Centre for Remote Sensing (ACRES) 1994.
- Division of National Mapping Macquarie Island 1:50 000 topographical map (1971) warped to conform with the satellite mosaic along the coastline and lakes.
- Incomplete aerial photography flown in 1976 (mainly in the north of the island).
- GPS positions and field observations.
Maps have been produced at three scales: 1:50 000 which covers the whole island, two 1:25 000 scale maps which split the island just south of Sellick Bay, and seven 1:10 000 maps which have a north-south extent of five kilometres.
Output is on an ink jet plotter and lamination of maps is recommended where outside use is envisaged (although a lamination service is no longer offered via MRT).
The data and a complete set of maps are available as a package for $165.
Digital data only - $55.
Maps can be purchased individually for $11 per map.
