This study performs visualization of a remote sensing images and adigital terrain model(DTM). A level 10 satellite image
which is anorthoimage could be registry with DTM to perform a correct perspective view. An aerial photograph, however, must be rectified in order to calibratethe relief displacement and system errors before visualization is performed.Hence, we
calcuate the six elements of exterior orientation by space resect method first, then create an orthoimage of aerial photograph with collinearity condition equations according to a DTM. The geocoded orthoimage of an aerial photograph can be easily integred into a Geographic Information System(GIS).
