An update to Keller Peninsula place names in the SCAR Composite Gazetteer of Antarctica
| Resumo: | Planialtimetric maps with good level of accuracy and at detailed scales may be used to improve geographic location information of the place names in the Composite Gazetteer of Antarctica (CGA), developed by the Scientific Committee on Antarctic Research (SCAR). In this study, a Geographical Information System (GIS) was used to obtain information on position and altitude of geographic features at the Keller Peninsula (KP), King George Island, Antarctica, as represented in a topographic map, a Digital Terrain Model (DTM) and an orthophoto. Using a GIS, points representing KP features were digitized, and their geographical coordinates and altitude were compared with the same features already recorded in the SCAR CGA. Among the 21 place names analyzed, only 3 showed correct location and altitude information. Nevertheless, we show that it is easy to update the SCAR CGA by using a GIS and planialtimetric data with good accuracy. |
