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.

GENERATING, STORING, UPDATING AND DISSEMINATING A COUNTRYWIDE 3D MODEL [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 As in many countries, in The Netherlands governmental organisations are acquiring 3D city models to support their public tasks. However, this is still being done within individual organisation, resulting in differences in 3D city models within one ...

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,

On the Reliable Generation of 3D City Models from Open Data
Urban Science, 2020 A 3D model communicates more effectively than a 2D model, hence the applications of 3D city models are rapidly gaining significance in urban studies. However, presently, there is a dearth of free of cost, high-resolution 3D city models available for use.

URBAN HEAT ISLAND MICRO-MAPPING VIA 3D CITY MODEL [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 Urban Heat Island (UHI) phenomenon has been a topic of intense study over the past several years. However, to visualise UHI model is still an issue. Common visualisation of UHI by using digital thematic maps shows that it is hard to perceive its impacts ...

Versioning of 3D City Models for Municipality Applications: Needs, Obstacles and Recommendations
ISPRS International Journal of Geo-Information, 2021 The use of 3D city models is changing from visualization to complex use cases where they act as 3D base maps. This requires links to registers and continuous updating of the city models. Still, most models never change or are recreated instead of updated.

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 ...
