This paper introduces character of SPOT image and explores the potential of SPOT image in comprehensive survey in Tangshan urban area. Seven thematic maps including landu-se

geomorphology

soil

vegetation

drainage

transportation and environment in Tangsan urban area were mapped by using 1:50000 SPOT color composite.From this study

it can be concluded:1. After geometric correction

the SPOT color composite with scale of 1:100000 possesses the best visual effects

and with scale of 1:50000 is the maximum scale among usable products and can be used to produce thematic maps of 1:50000.2. The smallest detectable area is of 25 m by 25 m

and the narrowest width of linear is about 10m in the SPOT color composites with scale of 1:50000. It can satisfy the requirement of land use survey at the district and county. I is an effectual way monitoring dynamic changes in the area. There is wide spread of application of SPOT image for comprehensive survey in the area.
