Bridge Renovation Planning – Orthophoto map and 3D model

Project Overview

A small footbridge (Mekinčeva brv) above the Gruber canal of the Ljubljanica river in Ljubljana was in need of renovation.

The bridge crosses the canal at 90 degrees, with its load-bearing construction being a reinforced concrete arch. The bridge was worn out to the extent that it demanded thorough renovation.

We intended to facilitate the project planning using aerial photographs, a calculated point cloud and an orthophoto map. This technology enables data collection even at hard-to-access sites such as bridges like this one. Apart from the photogrammetric measurements, we also carried out (in cooperation with a geodesic company) the calculations for a 3D geodetic plan.
