2.5 cm ground resolution, was changed in such a way that a 
ground resolution of 4 cm was finally obtained; this decision 
was made during the flight. In addition to the Athribis 
excavation area also one high resolution line was flown above 
Achmim, an archaeological site 10 km north-east of Athribis. In 
total 36 images were taken, with 4 cm, 10 cm and 25cm above 
Athribis, and 4 images with 2.5 cm above Achmim (figures 10 - 
13).

The acquired aerial images were used to produce digital 
elevation models with a raster width of 10 m for production of 
orthophotos with a GSD of 4 cm, 10 cm and 25 cm (figure 14). 
TLS control points in the vicinity of the temple were used as 
control points for the aerial triangulation. Concerning the 25cm 
orthophoto it was necessary to use some points from the Riegl 
laser scanner point cloud as additional control points.

In addition to these photogrammetric mapping results, also a 
digital elevation model with a raster width of 50 cm was 
calculated for the later fusion with the Riegl data (figure 15).
