For a geomatic application, it is necessary to georeference
the data. There are two common methods for that.
Direct georeferencing depends on the simultaneity of GPS
time and the camera inertial time. After the adjustment
of these data, the 3D georeferenced point cloud can be generated
directly. At the indirect technique, the Ground
Control Points (GCP) that were measured before the flight
by the method of RTK GPS surveying are used to georeference
the data. The color and size of GCPs must be suitable
to distinguish at the natural color of study area due to
marking them during the process. In this application, indirect
method was used to georeference with 27 GCP which
were measured by RTK with a base station top of the Afyon
Kocatepe University Faculty of Engineering faculty about
3 km away from the study area at ITRF96 datum and
2005.00 Epok. The accuracy of GCPs is calculated as
2.37 cm.
