(2) The triangulation to get the GCP on the ground with the
bundle block adjustment. This triangulation can be done after
identification from several snapshoots using the (old) aerial
photograph for gross orientation.
(3) The aerial triangulation itself, to orientate the (old) aerial
photographs using the GCP.
All of these triangulation could be done simultaneously in an
adjustment with adequate software.
With this method it is hoped that for most cases, a landing of
helicopter is not more necessary. Landing is the most critical
phase in the survey. Some potential GCP is not measured due
to the impossibility for the helicopter to have save landing.
This method should be tested during the end of the project in
2003. The result of the test should be then compared to the
conventional one. Unfortunately, an accident of one of
helicopter (crash against power line) has stopped the whole
operation. Mid 2004, the experiment is planed to be
continued.
Conclusion
This paper should give the idea of multi-triangulation as a
solution in a situation, where only old unpremarked aerial
photographs are exist. The briefly idea should encourage
researcher in photogrammetry to share the information, idea
and experience. Not all detail could be given in this paper due
to the restriction during the process of patent application.
