Photogrammetry Work Stage and Data

Pre Survey Photogrametry

This work covers:

• Planning of Coverage, Scale dan Tracks

• Select the aircraft and camera

• Select the Locations for Ground Control Points

GCP could be selected in pre/post survey.
In pre-survey, GCP could be premarked.
In post-survey, GCP must be selected in visible and measureable places (terrestric & on photo).

• Do the Aerial photogrphy

Post Survey Photogrammetry


This work covers:

• Aerial Triangulation (geometric correction and orientation a photo blocs with hundreds of photo simultaneously)

• Photogrammetric Compilation (interpretation)

• Map Editing

• Field Check (ground truth)

• Cartographic Finishing

• Printing (Offset)

Data for Photogrammetry Work


Overlapped Aerial photo (diapositif) to get 3D information wich is necessary to correct the geometry in hilly area.

Information of flight tracks (flight-plan)

Orientation data:
- Camera calibration information
- Ground control point with the sketch and description for each point
