A. Groung Control Points (GCP’s) and GPS Measurements
The flight process begins after the establishment and measurement of Ground Control Points that needed to to control and to enhance the quality of exterior orientation parameters (X0, Y0, Z0, ω, Φ, κ) obtained via GPS / IMU.

B. The Flight Plan
GPS / IMU, the units of the digital airborn camera, and flight control system allows us to take images in its right spatial location.

C. Imaging
The flight is carried out with respect to the flight plan in favorable weather conditions and the pictures are taken.

D. Enhancement
The digital photogrammetric maps are produced by the operators.

E. Orthophoto
Orthophoto map production process is also be done simultaneously with the production of vector maps.

Integrate the data, obtained by photogrammetric method, with a GIS.
