The purpose of this graduation thesis, placed in a selected area aerial photography (photogrammetric
block number 9, of the treaty of cyclic aerial photography of Slovenia in 2012), is to check the quality
of ground control points in the new coordinate system D96/TM by manufacturers of aerial surveys
used in the project aerial triangulation. From the records of ground points, led by the Surveying and
Mapping Authority of the Republic of Slovenia, we have selected three ground and three inaccessible
points, which we checked quality. The selection of ground control points was held in relation to the
maximum tolerance that was achieved after transformation from D48/GK coordinate system to
D96/TM coordinate system. The results showed that they are the largest in the area Trebnje, while
other ground control points we chose along between Ljubljana and Trebnje. Field measurement of
ground points was performed using the real time kinematic (RTK), while for inaccessible points we
used combination of GNSS and traditional terrestrial measurements. Then we compare coordinate
obtained by measurement and those that are kept on record at the Surveying and Mapping Authority of
the Republic of Slovenia. Based on the results, we commented on the appropriateness of ground
control points and in the completion of the task made the main findings and conclusions of the task.
The graduation thesis has arisen as a reminder that without quality input data production of the high–
quality finished products is not possible.
