Windmill Islands Satellite and Topographic Double Sided Image Map (edition 2) 1:50000

Full description

Satellite and topographic image map (edition 2) of Windmill Islands, Antarctica. A satellite image map (second edition) was produced in 1995, and a topographic map (second edition) was produced in 1997. A double sided map containing both the satellite and topographic maps was produced for the Australian Antarctic Division by AUSLIG (now Geoscience Australia) Commercial, in Australia, in 1997. Both maps are at a scale of 1:50000.

The satellite map was produced from merged SPOT multispectral and panchromatic data (341-487, 341-488). It is projected on a Transverse Mercator projection, and shows glaciers/ice shelves, station/bases, refuge/depot, sites of special scientific interest (SSSI), specially protected areas (SPA), and gives some historical text information. The map has both geographical and UTM co-ordinates.

Data sources for the topographic map are: Coastline, rock/ice interface, contours on rock and spot heights are produced from ANARE aerial photography (January 1994); Approximate contours north of Campbell Nunatak are derived from the November 1989 edition of the map; Approximate contours south of Campbell Nunatak are derived from Soviet mapping (1:100000)dating 1963. It is projected on a universal transverse mercator projection, and shows ship anchorages, traverses/routes/foot track charts, geology, glaciers/ice shelves, penguin colonies, birds, other fauna, stations/bases, refuge/depots, runways/helipads, sites of special scientific interest (SSSI), specially protected areas (SPA), and gives some historical text information. The map has both geographical and UTM co-ordinates.

Statement: Satellite map - Please see URL link given below ('Project Summary of Windmill Islands 1:50000 Satellite Image Map'). Topographic Map - Satellite Map-Data source: Merged SPOT multispectral and panchromatic data (341-487, 341-488), acquired 1 January 1989. Projection and Grid: Transverse Mercator, grid zone 49. Co-ordinates: Geographical and UTM. Horizontal datum: World Geodetic System 1984. Magnetic Variation: For Casey station 92.5 degrees west for January 1995 and moves westerly by about 0.1 degrees each year. Nomenclature: Names have been approved by the Antarctic Names Committee of Australia. Topographic Map-Data source: Coastline, rock/ice interface, contours on rock and spot heights are produced from ANARE aerial photography (January 1994); Approximate contours north of Campbell Nunatak are derived from the November 1989 edition of the map; Approximate contours south of Campbell Nunatak are derived from Soviet mapping dating 1963. Projection and Grid: Universal Transverse Mercator, grid zone 49. Co-ordinates: Geographical and UTM. Horizontal datum: World Geodetic System 1984. Vertical datum: Mean Sea Level. Magnetic Variation: Magnetic north is correct for 1995 and moves westerly by about 0.1 degrees each year. A diagram is given on the map showing true north, grid north and magnetic north for the centre of the map.
