3D scanning and modelling of the land in Arefu commune, jud. Arges for P.U.Z. documentation

Data acquisition

This studied area of 50000sqm required a 3D measurement of 120min. To ensure accuracy of 1-4 cm we used 25 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 equidistance of 1m
