Disclaimer
Information in the Antarctic Digital Database has been obtained from sources believed to be reliable but its accuracy and completeness, and the validity of the opinions based thereon, are not guaranteed. As every effort has been made to provide accurate information in this database, SCAR would appreciate it if users could indicate in writing any errors that may be noticed. SCAR is not inviting reliance on these data, and the user should always check original published data. The information in this database is subject to change
In particular, users should note the following:
- Data were gathered from sources at widely varying scales, and so the horizontal precision of the data is variable. The relative accuracy is no better than 50m, and in the worst case (indicated by small scale sources) can be up to 1 or 2 kilometres.
- The data were gathered from sources using a wide range of surveying and geolocation techniques. In many areas, the primary location is derived from an astronomical fix of low accuracy by modern standards. Therefore, absolute positions may be in error by 1 - 2 kilometres, or potentially more in areas distant from surveyed points.
- Not all features are mapped to uniform standards. For example, glacier margins and flow-lines are mapped in many areas, but not in the Antarctic Peninsula. The absence of a feature in these data does NOT necessarily indicate the absence of a feature on the ground.
- In any situation where safety of human life is at risk, the quality and reliability of the source data should be checked. Source data are listed in the bibliography.
- Users should note that the topography of Antarctica, especially the various ice masses, changes with time, and that these data may not represent the current status of features.
