“…3D models containing indoor can be used for route finding and accessibility [345][346][347][348][349][350][351][352], with specific applications such as evacuation [307,[353][354][355][356][357], navigating large train stations [358], determining indoor routes for the disabled [359], and locating the shortest path to the nearest automated external defibrillator [360]. Recent research efforts include the integration of indoor and outdoor routing for indoor emergency response facilitation [306].…”

In the last decades, 3D city models appear to have been predominantly used for visualisation; however, today they are being increasingly employed in a number of domains and for a large range of tasks beyond visualisation. In this paper, we seek to understand and document the state of the art regarding the utilisation of 3D city models across multiple domains based on a comprehensive literature study including hundreds of research papers, technical reports and online resources. A challenge in a study such as ours is that the ways in which 3D city models are used cannot be readily listed due to fuzziness, terminological ambiguity, unclear added-value of 3D geoinformation in some instances, and absence of technical information. To address this challenge, we delineate a hierarchical terminology (spatial operations, use cases, applications), and develop a theoretical reasoning to segment and categorise the diverse uses of 3D city models. Following this framework, we provide a list of identified use cases of 3D city models (with a description of each), and their applications. Our study demonstrates that 3D city models are employed in at least 29 use cases that are a part of more than 100 applications. The classified inventory could be useful for scientists as well as stakeholders in the geospatial industry, such as companies and national mapping agencies, as it may serve as a reference document to better position their operations, design product portfolios, and to better understand the market.

“…Personal movement within indoor spaces with or without explicit consideration for indoor way-finding or navigation has been the primary purpose of some other data models (e.g., Li, Claramunt, & Ray, 2010;Mandloi & Thill, 2010;Thill et al, 2011;Vanclooster et al, 2012), while cadastral considerations have led to yet another strand of literature (e.g., Billen & Zlatanova, 2003 There is a very limited body of literature on optimal location modeling for 3D indoor environments in spite of cities being increasingly removed from two-dimensional (2D) graph representations due to their vertical expansion. Notable exceptions include Arriola, Laporte, and Ortega (2005) and Dao, Zhou, Thill, and Delmelle (2012) in facility location planning and Plets et al (2012) and Wölfle, Wahl, Wertz, Wildbolz, and Landstorfer (2005) in wireless network planning. In all these bodies of literature, there is scant consideration for visualization and cartographic representation.…”

“…In all these bodies of literature, there is scant consideration for visualization and cartographic representation. The present study is motivated by recent work (Dao et al, 2012) that proposed a space-time facility location model for the interior space of multi-story buildings. In their study, the authors underscore the scarcity of concepts and tools for the effective and comprehensive communication of locational information in 3D networked spaces.…”

“…The example of spatio-temporal location modeling of AEDs within the confines of a multi-story building is used to motivate the study of 3D visualization techniques in support of indoor facility location planning (Dao et al, 2012;Thill et al, 2011). AEDs are devices that instrument the on-site treatment of persons in sudden cardiac arrest (SCA) by laypersons.…”

Abstract. In rescue missions or law enforcement applications, accurate determination of every team member's position and providing this information on a map may significantly improve mutual situation awareness and potentially reduce the risk of accidentally harming a team member. Furthermore, it could help keep track of the areas that have been already visited, helping the coordination of the mission at hand. Whereas in outdoors environments accurate positioning information can be obtained using a GNSS receivers, in indoor or underground environments GNSS signals are strongly disturbed and other means of localization must be called into play. Foot mounted inertial sensors or IMUs have been one of the proposed solutions, but their performance is prone to errors that grow over time. Only when the map of the environment is provided, can these IMUs perform with high accuracy. But building plans or maps of indoor and underground areas are often unavailable, outdated, incomplete and do not reflect furniture or other obstacles that also constraint the pedestrian's motion. How can a reliable map of an indoor environment be generated? FootSLAM -Simultaneous Localization and Mapping for pedestrians -is a novel technique based on foot mounted IMUs that measure the pedestrian's steps while walking. These measurements can be used to generate a map of an environment while determining the pedestrian's location within that map. FootSLAM was recently extended to FeetSLAM, the multiuser scenario in which the maps obtained by two or more pedestrians are combined to generate a more extensive and accurate map of the environment. In this paper we elaborate on different deployment scenarios for Foot-SLAM and its collaborative counterpart in security and emergency applications, yet to be experimentally validated.
