The data produced by photogrammetric methods have become used more effectively and efficiently to take
place of digital aerial cameras to aerial film cameras. Digital aerial cameras have distinct properties according
to imaging geometry, sensor numbers, the placement of camera cones and image recording techniques. Since
2000, many studies have been done upon the geometric analysis of the rapidly developing digital imaging
system. Intergraph DMC and Vexcel Ultracam are among the most popular digital imaging systems in this
area. These cameras are large-format digital aerial camera systems.
The purpose of the present study was to investigate the geometric performance of DMCII-250e and Vexcel
UltraCamX large-format digital aerial camera systems. The test flights were performed in Bursa province. Two
different image blocks which are 10 cm GSD and 30 cm GSD were acquired at different flight altitudes. The
image measurements for aerial triangulation were performed by Mescioglu Engineering Inc. The images were
processed with Match-AT software. It has been compared the residuals of coordinates and RMS of ground
control points and check points triangulated image blocks.
