It is desirable to use a photogrammetric scanner to minimize the errors from the scanning procedure in case of building aerial photo image DB. The photogrammetric scanner, however, is highly expensive to have only limited number of scanners available, therefore the general-purpose scanners have been considered as an alternative. This study has mainly been focused to see the possibility of the general-purpose scanner to be used for scanning aerial photographs. For that, the analysis of the image coordinates were made as well as the accuracy evaluation of each phase. In addition to that, as the application of the orthophoto images has been increased, the magnitudes of the errors from the DEM generation and orthophoto projection were analyzed. Also, the calibration program was developed to verify the geometric distortion of the automatic scanner to contribute to enhance the quality of the aerial photo image DB.
