The georeferenced filming of the main and secondary road network
of the Prefecture of Kavala and the island of Thassos has been
completed. The project was assigned by the survey consultancy firm
«Dimitrios Lagadianos» and involves the study of interventions to
improve road safety on the road network of Greece prefecture by
prefecture with the contracting authority of Egnatia Odos SA.
The services which were offered involved the recording with a
moving RTK of the external borderline on each road section and
traffic in both directions of the road to obtain the definition of
the axis of the recorded road sections and to determine its
geometry (straight parts and curves, in the horizontal and
vertical tracing as well as the inclination of the axis in its
length).
At the same time, another georeferenced filming in each separate
direction of each road section took place to identify
characteristic positions (barriers, embankments, road signs) and
to record the damage of the asphalt in order to identify possible
problems.
To complete this project, special metal pedestals were
manufactured by our company, which were placed on the roof of a
vehicle. Two high resolution (2048x1536) Arecont Vision cameras,
with a filming capacity of up to 30fps were placed on these
pedestals as well as a dual frequency GPS receiver with RealTime
capacity through GSM Modem.
