VELMAP is a compilation of ice velocity data of the Antarctic ice sheet and is intended for use by the polar scientific community. The data are presented in tabular form (ASCII format), containing latitude, longitude, speed, bearing, and error ranges. A metadata header describes the source of the data, the time of measurement, and gives details on measurement accuracy and precision.

The data sets were contributed by several investigators, in most cases from already-published work. Both in situ and image-based methods are used. References for the data sets are included with the data tables.

If you have any questions concerning the relevance of these data to your work please contact NSIDC User Services.



Data Contributions: If you have well-characterized Antarctic ice velocity data you would like to contribute to this site, please see the VELMAP pages for more information.
