This article deals with an attempt at indoor visual interpretation of the metric camera images of Rikaze area

Tibet plateau. It briefly introduces the basic parameters of the metric camera in European spacelab carried by the spacecraft during its ninth flight （STS-9/Spacelab） from Nov. 28th

1983. The supplementary maps were mapped using MC images of geological visual interpretation （such as drainage system

lineament and circular features）. The inter-pretated results of typical lithological chracters and structure were compared with Lansat MSS data. The conclusions are: （1） with MC images

the objects on ground are clear

（2） the bare area of bedrocks supplies abundant geological information

（3） the different rock unit can be easily distiguished （such as granite

basicultrabasic rocks

normal sedimentary rocks and volcanic rocks etc.）

and （4） some stratigraphic key horizons

the differentiation of strikes can be recognized

（5） most information of occurance can be identified and the fold structure can be inter-pretated qualitatively. The results of the inperpretation are very good

the dimensions

directions

combinations of the fault are reflected

and some blind faults can also be interpreted. The effects of interpretation of MC imagas excells that of the MSS images and can meet the needs of mapping standards at middle scale.
