Reconstructing historical 3D city models. [PDF]

open access: yesUrban Inform, 2022
AbstractHistorical maps are increasingly used for studying how cities have evolved over time, and their applications are multiple: understanding past outbreaks, urban morphology, economy, etc. However, these maps are usually scans of older paper maps, and they are therefore restricted to two dimensions.

Sharing 3D City Models: An Overview [PDF]

open access: yeseCAADe proceedings, 2009
This study describes the computing methods now available to enable the sharing of three-dimensional (3D) data between various stakeholders for the purposes of city modeling and considers the need for a seamless approach for sharing, transmitting, and maintaining 3D city models.

3D CITY MODELS FOR SUPPORTING SIMULATIONS IN CITY DENSIFICATIONS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021
In order to meet the increasing needs of housing and services in urban areas, cities are densified. When densifying a city, it is important to provide good living conditions while maintaining a low environmental impact. To ensure this, the urban planning

Incorporating Topological Representation in 3D City Models [PDF]

open access: yesISPRS International Journal of Geo-Information, 2019
3D city models are being extensively used in applications such as evacuation scenarios and energy consumption estimation. The main standard for 3D city models is the CityGML data model which can be encoded through the CityJSON data format.

TOWARDS AUTOMATIC SEMANTIC LABELLING OF 3D CITY MODELS [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
The lack of semantic information in many 3D city models is a considerable limiting factor in their use, as a lot of applications rely on semantics. Such information is not always available, since it is not collected at all times, it might be lost due to ...
