Summary
Laser Altimeters are very powerful tools for various applications in earth and planetary mapping. Altimeters have been in operation on spacecraft orbiting Earth, Mars, the Moon, Mercury, and small asteroids, to accurately measure global shape of the target bodies and to provide detailed maps of surface morphology. However, the accuracy of satellite laser altimetry is susceptible to real-time atmospheric conditions, within footprint topography fluctuation, detector noise, and so on. We proposed series methods to improve the quality of laser altimetry for earth and planetary topographic mapping applications.
