测高可能是观测冰盖最强大的工具之一。自1991年发射ERS1卫星以来，我们对南极冰盖的看法发生了深刻的变化。随着ERS2和Envisat的推出，该系列测高观测现在提供了19年的连续和同类观测，从而能够监测冰盖的形状和体积。由测高推算出的地形是揭示冰盖作用过程的相关参数之一。此外，高度计还提供了其他参数，如后向散射和波形形状，这些参数提供了表面粗糙度或积雪特征的信息。
Altimetry is probably one of the most powerful tools for ice sheet observation. Our vision of the Antarctic ice sheet has been deeply transformed since the launch of the ERS1 satellite in 1991. With the launch of ERS2 and Envisat, the series of altimetric observations now provides 19 years of continuous and homogeneous observations that allow monitoring of the shape and volume of ice sheets. The topography deduced from altimetry is one of the relevant parameters revealing the processes acting on ice sheet. Moreover, altimeter also provides other parameters such as backscatter and waveform shape that give information on the surface roughness or snow pack characteristics.
