Geolocation in 3D modelling refers to assigning real-world coordinates to a model so it accurately represents its location on the Earth’s surface. This process is essential for integrating models into larger contexts, such as city planning or geographic information systems (GIS). Geolocated models help stakeholders visualise projects within their actual environment, facilitating better decision-making and planning.

Geolocated vs. zeroed models

Geolocated Model - Aligns with specific real-world coordinates.

Zeroed Model - Sets the origin point (0,0,0) to correspond with a real-world location manually.

Georeferenced CAD Model/BIM - Embeds coordinate data within the model.

Rendering formats like FBX and OBJ do not support CAD/BIM georeferencing, requiring manual adjustment to align models correctly within VU.CITY.

Steps for Geolocation

Use CAD/BIM Software

When software doesn’t support georeferencing, it is necessary to zero the model. This involves setting the model’s origin point (0,0,0) to a specific location within the real-world coordinates.

After zeroing the model, import it into VU.CITY. Within VU.CITY, manually input the real-world coordinates to correctly align the model’s origin point with the intended geographical location.

Utilise Software Solutions

For a more streamlined process, utilise dedicated modelling software like Blender. VU.CITY developed plugin specifically designed to aid in zeroing and geolocating models.

Revit and SketchUp users can take advantage of VU.CITY’s plugins, which optimise and process models, facilitating easy import and accurate geolocation within the platform.
