PURPOSE: An enhancement method of an aerial photograph based on a digital mapping technology is provided to expand an application region of space information by easily performing digital mapping or solid reading. CONSTITUTION: An aerial photograph is photographed according to each project which forms a project set(410). A reference point measurement and an aerial triangle measurement are performed about each project(430). The aerial photograph is enhanced based on property information drawn from accuracy of each project, the reference point measurement, and the aerial triangle measurement. The property information is selected in groups composed of a project name, a coordinate system, a projection system, the number of models, position information, posture information, a scale coefficient, and a photographing date from inner information of each project. |
