The photorealistic model or the so-called 3D mesh is one of the possibilities of 3D representation of the city space. It is a continuous textured triangular mesh created photogrammetrically from oblique aerial photographs and airborne laser scanning data. The model is very detailed in terms of both the density of the triangular mesh and the texture resolution (approximately 5 cm/px). The density of the network is variable and depends on the granularity of specific areas of the model.

Mesh model

Because of its realism, the 3D mesh can give visitors to the city a new perspective on the areas they pass through and help them understand the structure and orientation of the city. The data can also serve as a basis for visualising new developments and other projects developing the public realm, offering the public a better insight into the future shape of the city.

Unlike the 3D model of buildings and bridges, mesh is not divided into individual objects. It is therefore not possible to assign additional information to individual buildings, isolate them or otherwise work with them in bulk at the object level. However, it has a colour texture, which brings an advantage especially in visualisation possibilities.

As the mesh is created by automatic image analysis (the imagery was captured in summer 2023), it contains all the objects captured in the images - vegetation, columns, urban furniture, means of transport, etc. Only small elements are filtered out by the algorithm - power lines, moving objects (e.g. people).

In the future, the data will be available as open data divided by a specific sheet clade in OBJ format. This format can be handled by common 3D modelling programs (Blender, 3DS Max, SketchUp, ...).

Currently we provide parts of the model free of charge on request.
