A CITYGML EXTENSION FOR HANDLING VERY LARGE TINS [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 Abstract. In addition to buildings, the terrain forms an important part of a 3D city model. Although in GIS terrains are usually represented with 2D grids, TINs are also increasingly being used in practice. One example is 3DTOP10NL, the 3D city model covering the whole of the Netherlands, which stores the relief with a constrained TIN containing more ...

3D As‐Built Environments in Extended Reality Applications: A Systematic Review
The Photogrammetric Record, Volume 41, Issue 194, April/June 2026.This systematic review identifies BIM and game engines as the primary tools for integrating 3D as‐built environments into XR. While multi‐sensor fusion and multimodal interaction enhance immersion, persistent challenges like manual modeling and bandwidth limitations continue to hinder full ecosystem maturation.

Open data‐based urban models: An assessment for Canadian cities
Canadian Geographies / Géographies canadiennes, Volume 70, Issue 2, Summer / été 2026.Abstract Digital urban models are a rapidly advancing area of study in urban design and policymaking. Many cities have adopted this technology, yielding promising results in developing localized models. However, there are only a limited number of recent Canadian examples, partly due to the high costs of model construction and maintenance.
