The BMP (bitmap data) for the scanned picture from the detailed contour line was converted to the segmentation bitmap picture through the threshold value processing. By analyzing this structure of the segmentation bitmap data, 1 Meter mesh coordinates of the contour line was acquired. 3D model was made from these data and it was used for the design, of road and for the scenery. The photograph which can be used as an aerial one is called a perpendicular photograph. It's inclination of the optical axis is 0 degree-3 degrees from a perpendicular angle. Other photographs are called oblique ones. In order to utilize this oblique photograph for GIS, some picture conversions were performed. From the result of superposition, the possibility to the application of a oblique photograph is explored. Moreover, the knowledge about the scale, rotation, and modification for being adapted in the basic theory of picture conversions is expressed.
