| The records do not support the idea of a sudden acceleration, and satellite altimetry suggests almost no change of sea level during the past decade. |
| Satellite altimetry has proved its worth in monitoring global sea-level change and will continue to be an important tool. |
| On the edges of the lake, they could see the lake bottom and thus measure its depth from altimetry, performing what Dr. Aharonson said was the first extraterrestrial bathymetry. |
| He has authored more than 30 journal articles on such topics as airborne laser altimetry, crustal deformation monitoring, and high-precision GPS reference networks. |
| A space altimetry mission allows us to measure, from a spacecraft in orbit, the relative or absolute altitude of the surface it flies over. |
| Moreover, altimetry data on wave heights and wind speeds are used in wave forecasting models. |
