Contour map has not enough information to support the road design or site location in this sophisticated age. To supply more information, orthophotomap has been, therefore, developed by adding the pictorial information to the contour lines. However, orthophotomap is rather expensive and unable of stereoscopic view. On the other hand, aerial photographs can be seen stereoscopically, while they has not uniform scale.<BR>In order to improve these inconveniences, a new technique has been developed in this study to form the digital terrain model and the digital photomap by using terrain data and pictorial data measured in the mesh system on the aerial photograph. This technique enables the conversion of digital terrain model with pictorial information in both ways between photo-coordinate system and ortho-coordinate system.
