Aerial photography sorties and GPS surveys are undertaken in Antarctica on alternate years to support a range of BAS mapping projects. A BAS Twin Otter, operating out of Rothera research station on Adelaide Island, provides the platform for the air camera.
In the UK, image analysis and photogrammetric techniques are used on collections of remotely sensed data, and digital topographic maps are compiled to meet the needs of BAS scientific and operational programmes. New and existing map sheets are described in the Map Catalogue. Existing and new survey data, air photography collections and map collections in the UK Antarctic Mapping Centre are recorded in catalogues.
MAGIC staff generate customized maps from the Antarctic Digital Database for in-house use, and co-ordinate production of paper sheet maps for publication.
The movie above shows changes in the Prince Gustav Ice Shelf since 1843. Observing change is one of the functions of GIS work in BAS.
In the UK, BAS topographic and scientific data are continually integrated in a GIS framework. Following on from the development of GIS for Rothera Point and Wright Peninsula, current effort is focussed on the preparation of a Signy GIS.
In the UK, the production of BAS geoscientific (BAS GEOMAP series) and all other BAS thematic maps is co-ordinated by MAGIC. Those maps published to date are described in the Map Catalogue.
