CityJSON

Versioning for Multi-LoD 3D City Model Management

Data Science, Geomatics / Leave a Comment

Researchers propose a framework for managing multiple Levels of Detail in 3D city models using CityJSON versioning, with each LoD in a separate branch for independent updates to geometries and semantics, tested on Dutch building data to assess feasibility and maintenance implications. Challenges in Managing Multi-LoD 3D City Models 3D city models are essential in […]

Reconstructing Historical 3D City Models from Maps

Data Science, Geomatics / Leave a Comment

Researchers at TU Delft present a methodology to generate plausible 3D city models from scanned historical maps, using alignment, procedural modeling, and height inference to minimize manual work and support applications like population estimation, disease mapping, and spatial simulations for European cities between 1700 and 2000.
