Altimetry is a technique for measuring height. Satellite altimetry measures height by means of counting the time taken by a radar pulse travelling from the satellite antenna to the surface and back to the satellite receiver.
Discussions about satellite altimetry from researchers in the world mainly focuses on sea surface, less attention is drawn to terrestrial surface. However, except measuring height we have discovered a fact that Satellite altimetry is also able to detect vertical distribution of groundwater which Satellite gravimetry fails to carry out. This is because both of them has different work functionality. In order to emphasize on difference, named as terrestrial altimetry. It looks simple, however actually many important mechanisms are hidden in the process. Unfortunately, they have completely been ignored by researchers in the world. Their understanding altimetry remain at the concept of height; therefore, they may treat terrestrial surface as “steel-plate –like” plain. Owing to influence of terrain, researchers lost their thought into its complexity. Few researches in the world have paid their attention to this field.
