Kurzfassung

Starting with the Apollo program, increasingly precise orbital and Earth-based measurements of the topography of the Moon have been performed with radar and laser altimeters. Orbital measurements are the most accurate, being relative to the center of mass, while Earth-based radar must generally be adjusted to match controls. Recent data from high-resolution laser altimeters reveal substantial errors in earlier datasets. We present the results of over 2.4 billion measurements (as of Sept. 1, 2010) from the Lunar Orbiter Laser Altimeter (LOLA), with near-global coverage, 10-cm vertical precision, and meter-level radial accuracy, to which datasets from the Arecibo and Goldstone radar, the photogrammetric Unified Lunar Control Network 2005, and from the Clementine (DOD), LALT (JAXA), LAM (CSA) and LLRI (ISA) laser altimeters may be compared. The geodetic network being generated by LOLA will be applied to images and stereophotogrammetric solutions being generated by the Lunar Reconnaissance Orbiter to create a reference dataset suitable for exploration and science. The LOLA data, either as 5-point multibeam swaths or as digital elevation models, may also be used to assess the orbital, attitude, and timing accuracy of other mapping instruments. Examples will be shown using the densely-sampled, polar 20-m digital elevation models being provided to the Exploration Systems Mission Directorate and Planetary Data System of NASA as part of the LRO Project. With other altimetric datasets and mapping camera solutions filling in the gaps between LOLA swaths, a consistent, accurate, and international altimetric dataset will emerge.
