Call for Papers: New techniques and Methods for Modelling, Visualization and Analysis of 3D Cities
Guest Editors: Shen YING, Peter VAN OOSTEROM, Hongchao FAN
Semantics, spatial forms and spatial relationships of 3D city objects are fundamental for smart cities. Modelling the 3D cities includes extracting the semantics and spatial geometry of 3D city objects and reconstruct city scenes with them to support precise 3D city analysis, like sunlight and heat analysis, airflow in 3D environment and applications, i.e. facility management, energy simulation, disaster management, digital government. Technical progresses have provided advanced 3D data collection approaches for 3D city objects. For the area-wide reconstruction of 3D building structures and 3D cities, airborne image or LiDAR data is usually used, leading to building models with detailed roof structures but planar facades (LOD2). Data acquisition and 3D modelling for more detailed building representations showing explicitly modelled facade structures (LOD3) require high cost in time and money, and, up to now, they are only possible for selected areas. The even more challenged tasks are automated semantic labelling of city objects at different hierarchies and modelling semantic information with geometries. In the domain of 3D visualization, a number of solutions with different 3D engines have been made available, including the most advanced WebGL techniques such as Cesium. Unfortunately, semantic information which is coherent with geometries of 3D buildings on different hierarchies is rarely considered during the visualization. And thematic or style-driven visualization is not sufficient to support displaying the area of interests. For this reason, 3D interactions are much limited in the visualization.
This topical collection (special issue) is dedicated to this exciting new domain. It aims at publishing the state of-the-art research efforts that address the challenges of reconstruction and visualization of 3D city models with full consideration of semantic, structural and scene information. Both comprehensive scientific review papers and research articles are welcome. Potential topics include (but are not limited to) the following points: 3D City Modelling Building Information Model Reconstruction of 3D city scene 3D City Space Analysis 3D spatial relationship between city objects 3D City Visualization Indoor mapping 3D city model with footprints and point cloud Automated 3D acquisition and reconstruction techniques Semantic labelling of façade/roof structures from image data / 3D point clouds 3D city model identification by deep learning WebGL based 3D visualization for 3D cities with semantics.

The topical collection (special issue) will be closed on 30 April 2020.
