3 SEMI - AUTOMATIC AERIAL TRIANGULATION
Operator and automatic point transfer did point selection and measurements by digital image matching using
ImageStation 6487 with ISDM INTERGRAPH software. In the each of the Gruber regions two tie points have been
measured and transferred to all photos by correlation method. Natural points of good quality and contrast have been
used as tie points. After measurements Least Square Matching (LSM) has transferred them to all overlapping
photographs. About 26 tie points have been recorded for each photo.
Both blocks were adjusted with BINGO-F 4.0 software. Due to systematic deformation errors of duplicate diapositives
block No.2 was adjusted with additional self-calibration parameters.
Data of semi-automatic aerial triangulation are shown in Table 2.

4 AUTOMATIC AERIAL TRIANGULATION
Interior orientation parameters, GCP’s and checkpoints data have been imported from semi-automatic measurements.
Automatic Aerial Triangulation was performed on Image-Z with MATCH-AT Inpho version 2.0.0.6 software with
following parameters:
- splitting factor - 4;
- number of tie points per area - 14;
- matching strategy - most accurate.
