“…The observation that mare surfaces fall close to an ellipsoidal surface lead to the hypothesis that mare basalts originated in the deep interior and flooded Serenitatis and the other nearside basins to an equipotential level (Runcorn, 1974;Sjogren and Wollenhaupt, 1976;Brown et al, 1974;Smith et al, 1997). A recent analysis by Arkani-Hamed et al (1999) suggests that basins flooded to local rather than a global equipotential surface.…”

“…absolute vertical accuracy is estimated to be 100 m (Zuber et al, 1994;Smith et al, 1997). The LIDAR data are the best elevation data available for Mare Serenitatis since the accuracy of stereo-derived data are limited over relatively featureless mare surfaces (Cook and Robinson, 1999).…”

“…Spudis et al (1994) estimate that within an orbital track, valid topographic measurements may make up as little as 15% of the total returns in very rough terrain near zero solar phase angle or nearly 100% of the returns for smooth maria overflown late in the mission when solar phase angles were larger. Although the distributions of valid returns and thus the spatial resolution within an orbital track is variable, the single-shot ranging precision of the LIDAR is 40 m and the LIDAR data were exhacted from the data set of Smith et al (1997). Elevations are in meters above an ellipsoid of radius 1738 km at the equator with a flattening of 113234.93 corresponding to the flattening of the geoid, and the vertical exaggeration is 80:l.…”

“…2) that shows a general increase in elevation of the mare surface from south to north. A digital elevation model (DEM) of Mare Serenitatis was extracted from the global lunar DEM generated using the LIDAR data by Smith et al (1997). The global lunar DEM has grid resolution of 0.25" x 0.25", corresponding to the minimum spacing between orbital passes .…”

Major advances in the application of satellite radar altimetry have led the way to a proven ability to determine surface water height, or stage, for some of the largest rivers, wetlands, and lakes around the world. These developments have come at a time when global water resources are of major concern, and there is a much‐noted decline in ground‐based monitoring networks. Recent interferometric synthetic aperture radar studies have also demonstrated the ability to retrieve stage changes over a wide expanse of inundated floodplain or wetland. While the performance of these radar instruments is continuously being assessed, focus is also on the potential of satellite‐based laser altimetry, which may offer smaller observable targets and improved stage accuracies. With these technological capabilities, we have the capacity to determine inland water stage, and to some degree, river width and gradient.

Light detection and ranging, or lidars, have emerged as a type of powerful tools in remote sensing from space. Compared with radars, lidars operate at a much shorter wavelength with a much narrower beam and smaller transmitter and receiver. Compared with passive remote sensing instruments, lidars carry their own light sources and can continue measurement day and night, and over polar region. Compared with spectrometers, lidars offer a much higher spectral resolution and consistent illumination and observation angles. This article gives a brief review of the development of space lidars used in planetary surface elevation and reflection measurements, including the history of laser altimeters in space, basic instrument design, and the trend of the technology development.
