In this contribution, stereo photogrammetric evaluation was
performed by using aerial photographs of Ardeen region
(Ortaalan Village) in Rize. Digital Photogrammetric
Workstation Zeiss SSK by Z/I Imaging was used for
photogrammetric evaluation. After pre-processing, the different
dated images scanned with 21 micron precision and covered the
selected area was transferred to the system. To establish the
relationship between object space and image space, the ground
control points were selected in model area to be able to do all
measurements in Natiaonal Coordinate System. These points
coordinates were measured using GPS (Global Position System)
technology. Then, inner, relative and absolute orientations were
respectively performed (Figure 4). At the result of the absolute
orientation, the accuracy was obtained 45 cm in planimetry (x,
y), 50 cm in height (z)
