“…Mixed levels of realism have been proposed for regular maps used for data exploration purposes (Jenny et al 2012) as well as for VR. In VR, egocentric-view-VR representations with selective photorealism (a mix of abstract and photorealistic representations) have been tested in the context of route learning, memory, and aging and have been shown to benefit users (Lokka et al 2018;Lokka and Çöltekin 2019).…”

“…In some cases, we need to follow the "Goldilocks principle" because too much or too little realism is suboptimal. As Lokka and Çöltekin (2019) demonstrated, if there is too much realism, we may miss important details because we cannot hold all the details in our memory whereas if there is too little, we may find it difficult to learn environments because there are too few 'anchors' for the human memory to link new knowledge of the environment. These issues of how to abstract data and how it can be effectively visualized for end users are growing in the era of big data and Digital Earth.…”

In this chapter, we review and summarize the current state of the art in geovisualization and extended reality (i.e., virtual, augmented and mixed reality), covering a wide range of approaches to these subjects in domains that are related to geographic information science. We introduce the relationship between geovisualization, extended reality and Digital Earth, provide some fundamental definitions of related terms, and discuss the introduced topics from a human-centric perspective. We describe related research areas including geovisual analytics and movement visualization, both of which have attracted wide interest from multidisciplinary communities in recent years. The last few sections describe the current progress in the

“…rendering, stylization and interaction 3D geovisualization, especially for urban analysis purposes, is widely explored in geographic information sciences. Most of all, issues of data pre-processing, for instance the Level Of Detail (Biljecki et al, 2014), rendering (Trapp et al, 2011) and stylization (Brasebin et al, 2016) of 3D urban models are often at stake, based on interactive systems offering interaction and navigation, between rendering styles (Semmo et al, 2012, Boér et al, 2013, Semmo and Döllner, 2014 or into the scene (Devaux and Brédif, 2016), favoring visual attention Çöltekin, 2012, Bektas et al, 2015) or usability by final users (Lokka and Çöltekin, 2017). In previous works, we have been specifying a 3D geovisualization pipeline (Brasebin et al, 2016) inspired from the cartographic pipeline designed in (Christophe et al, 2016), based on each of the following main processes of geovisualization: 3D data modeling, rendering, stylization and interaction.…”

<p><strong>Abstract.</strong> In this paper, we assume that augmented reality (AR) and mixed reality (MR) are relevant contexts for 3D urban geovisualization, especially in order to support the design of the urban spaces. We propose to design an in situ MR application, that could be helpful for urban designers, providing tools to interactively remove or replace buildings in situ. This use case requires advances regarding existing geovisualization methods. We highlight the need to adapt and extend existing 3D geovisualization pipelines, in order to adjust the specific requirements for AR/MR applications, in particular for data rendering and interaction. In order to reach this goal, we focus on and implement four elementary in situ and ex situ AR/MR experiments: each type of these AR/MR experiments helps to consider and specify a specific subproblem, i.e. scale modification, pose estimation, matching between scene and urban project realism, and the mix of real and virtual elements through portals, while proposing occlusion handling, rendering and interaction techniques to solve them.</p>

“…Why are there such differences, and can we design the content in a way that benefits everyone? Lokka and Çöltekin (2019) take an interest in this question, from an abstract-and-realism lens in their paper titled 'Toward optimizing the design of virtual environments for route learning: empirically assessing the effects of changing levels of realism on memory'. In this comprehensive controlled experiment, Lokka & Çöltekin compare three levels of realism in the context of route learning, demonstrating that using the photo-textures selectively in a virtual environment meant for route learning is beneficial in terms of short-and long-term recall of routes.…”

Where are we now? Re-visiting the Digital Earth through human-centered virtual and augmented reality geovisualization environments The original Digital Earth concept, formulated by Al Gore (1998), is essentially a virtual reality system. In this (imagined) system, users are able to freely explore all possible recorded knowledge or information about the Earth though an interactive interface. While we imagine such an interface primarily as visual for now, it can be expected that in the future other senses will be engaged, allowing for even more realistic virtual experiences. Even though 'realism' in the experience is desirable (i.e., it feels real), immersive experiences provided by visualization environments can go beyond reality, as they can be enhanced with queryable information. Of course one can also create fictitious experiences and simulations in such environments; including information about possible pasts (e.g., ancient Rome) and futures (e.g., a planned neighborhood); or spaces that we cannot (easily) directly experience (e.g., the Moon, Mars, other faraway spaces, under the oceans, core of the earth, etc.). At the time of this writing, there is a new wave of excitement across scientific communities and commercial markets about virtual, augmented and mixed reality technologies. Various forms of virtual reality (VR), such as stereoscopic displays, have seen such waves of excitement in the past (see Gartner's hype cycles, Linden and Fenn 2003). VR experiences appear to inspire people, but the excitement about VR displays tend to not last too long, perhaps partly because of the cumbersome hardware and the amount of involvement their setup requires. Current VR technologies offer better visual quality, somewhat easier-to-setup hardware, and more realistic virtual experiences; and are more affordable compared to previous generations. Nonetheless, only time will tell if VR will remain a mainstream display technology this time around. Augmented reality (AR) on the other hand, has only been experimental until recently, and is new to mainstream attention. Dedicated headsets, such as Microsoft Hololens (https://www.microsoft. com/en-us/hololens), MagicLeap (https://www.magicleap.com/) or similar, offer full state-of-theart AR experience with hand-and head-tracking, but importantly, there are already convincing and functioning AR applications for smartphones without having to wear a 'helmet' (e.g., see augmentedcreativity.ch, https://highlights.ikea.com/2017/ikea-place/). These AR applications for mobile phones make a strong case for the durability of AR, because this way, technology addresses a much wider audience. In other words, perhaps not many people will invest in dedicated headmounted displays, whereas many people already have smartphones. This prediction will depend on the developments of the next generation of smartphones, but we envision that with continued development of the 'Internet of Things' (IoT), such mobile AR applications will eventually allow us to point our device to any object containing a chip ...
