火星地形测图

Topographic Mapping of Mars

火星地形数据是火星探测的基础数据，从登陆点的选择到表面形态学的定量分析，从火星漫游车的行进到火星物质采掘都离不开影像和三维地形数据。本文论述了火星地形测图的最新进展，分析了火星全球勘探者、火星快车、火星勘测轨道器等环火星轨道器的测图传感器性能、数据处理技术以及火星地形测图产品，指出了火星地形测图未来发展的一些趋势。

Topographic data of Mars surface is the basic information for Mars exploration. The images and 3D Topographic data is needed for Mars exploration from selecting landing site to analyzing morphological information, from moving for Mars rover to digging Mars matter. This paper introduces the latest advances in Mars＇ s topographic mapping, and analyzes the mapping sensor performances data processing technologies and map products for Mars Global Surveyor, Mars Express and Mars Reconnaissance Orbiter. Some development tendencies in Mars mapping are prospected.
