摘要: Lunar topographic information is of paramount importance for lunar exploration missions and scientific investigations. For models derived from different sources or missions, it not uncommon to see inconsistencies among them. This paper presents a detailed comparative analysis the Chang’E-1 SELENE altimeter data. A least squares matching method developed register one model other through seven parameters transformation (three translation parameters, three rotation scale factor). Two typical study areas on Moon are selected investigation, including Sinus Iridium (the primary candidate landing site area future Chinese robotic human landed missions) Apollo 15 area. Experimental results indicate that there small shifts in both horizontal vertical directions between these two data sets. After shift removal, topography sets show consistent trend.
