The goal of VELMAP is to compile ice flow velocity for the whole Antarctic continent from all sources. Ice flow and its temporal changes are among the most fundamental parameters of the Antarctic Ice Sheet. Understanding these is essential to answering questions about whether the volume of ice is changing and how it may change in the future. Since changes in Antarctic ice have an impact on sea level, this is a problem with global importance.
