Incorporating Topological Representation in 3D City Models [PDF]
ISPRS 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.

Reconstructing historical 3D city models. [PDF]
Urban 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.

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

INTEGRATING SCALE AND SPACE IN 3D CITY MODELS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 This paper presents the problem of the current separate treatment of levels of detail in city models. We propose a solution, detail the main principles, and present our initial results on the approach.

Building modeling for 3D city model [PDF]
Geo-spatial Information Science, 1999 New development in urban planning, cityscape, real estate management and the like, calls for new demands for 3D city model. There are so many objects in 3D city model such as building, river, road, and so on. The building model is very important in 3D city model. In recent years, a lot of research work about visualization has been done. In our opinions,

Requirements, Development, and Evaluation of A National Building Standard—A Swedish Case Study
ISPRS International Journal of Geo-Information, 2020 The aim of this paper is to present a proposal for a national building standard in Sweden. We define requirements for the proposed standard, e.g., it should support development of 3D city models, connect to building information models (BIM) and national ...
