摘要：The increasing volume of planetary lidar data is creating global datasets of unprecedented resolution and accuracy, and presenting new challenges. From 1971-72, when three Apollo missions carried laser altimeters to the Moon, to the Mars Global Surveyor mission operating the MOLA instrument for nearly 1000 days, the number of planetary ranges has in- creased by more than 5 orders of magnitude, and accuracy by nearly 3 orders. Significant refinements to orbital and attitude knowledge result from the use of millions of altimetric crossover constraints
