Project details

This case focuses on the 3D methodology for the production of accurate geographical data for the PUZ documentation that underpins the Building Permit

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.

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 0.5m equidistance.
