“…The popular topics of applying BIM-GIS integration on buildings also include indoor navigation [92], heritage protection [22,23,[93][94][95][96], construction supply chain management [15,97], mega projects management [98], ecological assessment [25], etc. For the applications of BIM-GIS integration on cities, 3D urban modeling and representations [99][100][101], urban facility management [28,102], and emergency response [103] are the primary aspects at the beginning of the integration attempt. In recent years, more studies utilize BIM-GIS integration to characterize human activities and their relationships with cities, such as traffic planning and analysis [104,105], walkability analysis [106], and energy assessment and management [10,[19][20][21][107][108][109].…”

The integration of building information modelling (BIM) and geographic information system (GIS) in construction management is a new and fast developing trend in recent years, from research to industrial practice. BIM has advantages on rich geometric and semantic information through the building life cycle, while GIS is a broad field covering geovisualization-based decision making and geospatial modelling. However, most current studies of BIM-GIS integration focus on the integration techniques but lack theories and methods for further data analysis and mathematic modelling. This paper reviews the applications and discusses future trends of BIM-GIS integration in the architecture, engineering and construction (AEC) industry based on the studies of 96 high-quality research articles from a spatio-temporal statistical perspective. The analysis of these applications helps reveal the evolution progress of BIM-GIS integration. Results show that the utilization of BIM-GIS integration in the AEC industry requires systematic theories beyond integration technologies and deep applications of mathematical modeling methods, including spatio-temporal statistical modeling in GIS and 4D/nD BIM simulation and management. Opportunities of BIM-GIS integration are outlined as three hypotheses in the AEC industry for future research on the in-depth integration of BIM and GIS. BIM-GIS integration hypotheses enable more comprehensive applications through the life cycle of AEC projects.

International audienceDue to the advances in computer graphics and improved network speed it is now possible to navigate in3D virtual world in real time. Until now, technologies employed require to install standalone application orplugins on navigators. The arrival of HTML 5 brings news solutions to visualize 3D data in a browser withWebGL. Several globe projects have proven that such technologies can be employed. Unfortunately, demonstrationsare often based on proprietary formats to exchange or to store data. In this work, we propose touse CityGML: a standard provided by the Open Geospatial Consortium. CityGML files are imported in ourEnvironment Editor. With several tools that we present in this paper, data are processed and stored. A clientserver application is also presented to permit the visualization of geometry and semantic in a navigato

“…LOD0 represents large landscape level; LOD1 represents city level; LOD2 represents means city block level; LOD3 defines a general sense of the city building; LOD4 contains the inside information in a building. Besides, OGChasn't given the LOD criterion under the scale of the buildings themselves [1][2][3] . In the constructing of Digital City, usually it is necessary to set up the LOD mechanism of building itself.…”

The characteristics of rapid parallel computing of modern computer hardware are utilized in this paper. Hierarchy structures of CityGML building models are constructedin CPU dynamically by taking advantage of their spatial patterns and semantic relations. We present an approach for sending modification data to GPU buffers in batches so that communication between CPU and GPU can be reduced as much as possible. According to the data created by the hierarchy information dynamically in GPU, the corresponding level detail building models will be rendered under the using the properties of parallel handling of geometry shader. Therefore, powerful multi-threaded computing ability of GPU is utilized more effectively. The experiment results prove that our methods run more efficiently while consume less CPU and GPU footprints, and also can meet the demand of large-scale urban building models.
