“…For instance, they are used in estimating the visibility of a landmark [182,183], assessing façade visibility for city marketing [184,185], in determining the optimal location for surveillance cameras [186][187][188], sensor coverage assessment [189], improving road safety [190], assessing sniper hazards [191], and in real estate mass valuation in the urban areas, based on the assumption that the view from an apartment is one of the factors driving its price [192][193][194]. Further applications involve predicting the visibility of GNSS satellites in the built environment and mitigating the multipath effect [195][196][197][198][199][200][201][202][203][204].…”

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.

“…At different distances (4.8 m, 2.4 m and right on the end line of the corridor), the wall with the local material will be seen differently. Some studies of visibility also shown from where an object can be visible to the observer [11,12]. This study showed not only where an object can be visible by the observer, but also how visible the object is by measuring the region area using MatLab.…”

The Role of Local Materials in Creating A Meaningful Visual Experiences in Urban Public Facilities

This paper discusses visibility potential of local material products that are used as part of architectural spaces. Knowing the visibility potential of local materials is essential to create visual clarity that supports the ease of spatial orientation and navigation and provides a meaningful visual experience in urban public facilities. This study aims at finding the property quality of objects from local materials that contribute to the visibility potential. Field studies were conducted to identify different types of products from local materials and their characteristics associated with the quality of space experience. The visibility analysis using 3D software program then was carried out by simulating the placement of objects as elements of space in a particular spatial configuration. The result reveals several patterns of possible placement of objects from local materials that have the best potential to enhance visibility. These patterns can add to the alternative vocabulary in architectural design.

“…The ability to ignore irrelevant information may improve learning performance, but in some cases, it can deteriorate learning performance. Inattention to global environmental cues might be disadvantageous for spatial learning because global cues serve as orientation beacons (Steck & Mallot, 2000) that impose an absolute reference frame (O'keefe & Nadel, 1978), help users align spatial information, and determine the relative location of routes and landmarks in the environment (Gunzelmann & Anderson, 2006;Delikostidis et al, 2013). With these roles in mind, we defined global landmarks for the present study as peripheral and highly salient environmental cues that can be observed from a large portion of the environment and remain relatively constant in relation to the short distances travelled by the observers (Steck & Mallot, 2000).…”

The influence of stress states on cognition is widely recognized. However, the manner in which stress affects survey knowledge acquisition is still unresolved. For the present study, we investigated whether survey knowledge acquisition during a stressful task (i.e., under time pressure) is more accurate for the mental representation of global or local landmarks. Participants navigated through virtual cities with a navigation aid and explicit learning instructions for different landmark configurations. Participants' judgments of relative direction (JRDs) suggest that global landmark configurations were not represented more accurately than local landmark configurations and that survey knowledge acquisition was not impaired under time pressure. In contrast to prior findings, our results indicate the limitations of the utility of global landmarks for spatial knowledge acquisition.
