3D modelling and digital twins

Sector: Cities and territories

Activity: Earth observation

Disciplines: Maps, remote sensing and artificial intelligence

Against a backdrop in which cities have become larger and more populous, and in which technology opens new possibilities to observe and mimic dynamic urban processes, the concept of the digital twin (DT) takes on greater relevance.

For this Digital Twin to be integrated with sensors and BIM data, it is necessary to have a more realistic outlook and recreate the urban environment in 3D. COTESA boasts an in-house algorithm that generates the boundaries of all buildings, models them in 3D with pressure of less than one metre and featuring realistic texturisation.

 

Solution

In-house algorithm based on AI

Generation of buildings’ limits

Obtaining height levels of blocks of buildings

Modelling using photorealistic textures

Time analysis of cities

Deliverable in vectorial (SHP, DXF) and 3D (Collada, SLPK, etc) formats

An opensource or proprietary viewer can be integrated
