Scanning and 3D modeling of the communal road in the county of. Arges for P.U.Z. documentation

Data acquisition

This 7km surveyed area required a 240min 3D measurement. To ensure accuracy of 1-4 cm we used 50 RTK GPS points for further post-processing and error assessment.


Image processing was done using specialised 3D software. GPS points determined in the field were used to generate a dense 3D point cloud georeferenced in the national reference system “Stereo 70”.

The following results were provided: a 3D model, georeferenced orthophoto plan, topographic survey with contour lines with 0.5m equidistance.
