3D model, topographic survey with contour lines and orthophotoplan

Data acquisition

This 15000sqm studied area required a 60min 3D measurement. To ensure accuracy of 1-4 cm we used 10 RTK GPS points for further post-processing and error evaluation.

Results

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 0.3m equidistance.
