| Abstract: | The development of land-sea satellite laser altimetry is an important choice to adapt to the new situation and meet the new needs. The demands in various aspects are analyzed, including the data acquisition of high precision elevation control points, the estimation of forest biomass, the surveying and mapping of shallow water topography and island reef topography, the monitoring of tripolar regional elevation and so on. A preliminary idea of developing a new multi-beam laser altimetry technology is put forward, and the several key technical issues, including highly precise pointing determination, dynamic adjustment of range gate width and so on, are discussed. |

| Keywords: | satellite laser altimetry precise pointing determination elevation surveying land and sea surveying and mapping biomass estimation tripolar region |
