Research on immersive virtual reality (VR) indicates that VR technologies facilitate understanding through the formation of spatial presence, which is the user's feeling of "being there" in a virtual place. These findings make VR a highly interesting tool for geographic information science and the visualization of geospatial phenomena. However, immersion and presence are often studied under laboratory conditions, while research on virtual representations of real-world environments is still rare. This paper aims to reduce this gap empirically through a user study on spatial presence in immersive geo-environments. A total of 60 subjects entered a VR replica of a coral reef in the Mexican Caribbean built upon WorldView2 imagery. After testing within-and between-subject performance under both VR headset-and desktop-based visualization conditions, all users completed the IPQ self-report questionnaire to evaluate the sense of presence experienced. The results indicate a strong effect of immersion, leading to statistically significant higher levels of spatial presence in immersive geo-environments. Keywords Virtual reality • Spatial presence • Immersion • Geovisualization • Immersive geo-environments Zusammenfassung Räumliches Präsenzerleben in immersiven geographischen Umgebungen-eine empirische Studie. Aktuelle Forschungen weisen darauf hin, dass mittels immersiver virtueller Realität (VR) ein intensives räumliches Präsenzerleben (Telepräsenz) erzeugt werden kann, bei dem sich NutzerInnen im virtuellen Raum anwesend bzw. handlungsfähig fühlen. Empirische Studien legen außerdem nahe, dass mit dem Gefühl der Telepräsenz ein gesteigertes Interesse am dargestellten Sachverhalt bzw. ein besseres Verständnis desselben einhergehen. Da es den Geoinformationswissenschaften immer auch um die möglichst gute Vermittlung raumbezogenen Wissens geht, kommt dem Phänomen des räumlichen Präsenzerlebens besondere Bedeutung für die Geovisualisierung zu. Allerdings stützen sich empirische Befunde zur Wirkung von VR meist auf fiktive Umgebungen, während georeferenzierte geographische Räume bislang weitgehend unerforscht sind. Der vorliegende Text möchte diese Forschungslücke anhand einer Nutzungsstudie zur Telepräsenz in einer realistischen immersiven Umgebung verkleinern. 60 ProbandInnen testeten eine satellitenbild-und eine GIS-basierte virtuelle Repräsentation eines Korallenriffs. Sowohl inter-als auch intraindividuelle Leistungen wurden unter immersiven (VR-Brille) und desktop-basierten Untersuchungsbedingungen verglichen. Die Ergebnisse sprechen für einen starken Einfluss von Immersion auf die NutzerInnen, welcher in einem statistisch betrachtet signifikant höherem Präsenzerlebnis in immersiven Geovisualisierungen zum Ausdruck kommt.

“…The method is designed according to the current state of the art in the field of VR and photogrammetry application for cultural heritage, adopting the most widely used software tools. The workflows connecting photogrammetry and VR represent an important topic in the field of cultural heritage [19,20,[26][27][28]. Soto-Martin et al [20] presented a digital reconstruction of a historical building as an interactive and immersive experience in virtual reality.…”

Virtual Reality Models Based on Photogrammetric Surveys—A Case Study of the Iconostasis of the Serbian Orthodox Cathedral Church of Saint Nicholas in Sremski Karlovci (Serbia)

During recent years, the synergy of virtual reality (VR) and photogrammetry has become an increasingly prevalent way to visualize, represent, preserve and disseminate cultural heritage objects. Photogrammetry offers a reliable method for a faithful and accurate image-based modeling of real-world objects, while VR applications provide not only visualization, but also an immersive and interactive experience of the photogrammetrically reconstructed cultural heritage. This research aims to create and apply the method for providing VR experience in the context of cultural heritage by developing a workflow for the VR applications based on photogrammetric models. The proposed workflow was applied on the iconostasis of the Serbian Orthodox Cathedral church of Saint Nicholas in Sremski Karlovci (Serbia). The presented method is based on the following main steps: generation ofan accurate 3D reconstruction of the iconostasisusing photogrammetry, the 3D model optimization, retopology, control and analysis and the process of creating the VR experience using a game-engine. The final result is an interactive walk through the church, which provides the user with an opportunity to visualize the iconostasis and its individual icons through different perspectives and multiple levels of detail, which is not otherwise possible when observing the church interior.

“…TLS was bundled with photogrammetry for better visualization as reported in literature (Alshawabkeh & Haala, 2004;Cabrelles et al, 2009;El-Hakim et al, 2004;Grussenmeyer et al, 2008;Guidi et al, 2009;Remondino, 2011;Yastikli, 2007). Moreover, TLS has been bundled up with Virtual Reality to better visualize heritage (Fernández-Palacios et al, 2017;Tan et al, 2016;Basantes et al, 2017;Tschirschwitz et al, 2019;Forte et al, 2004;Kersten et al, 2017Kersten et al, , 2018aKersten et al, , 2018b.…”

Digital documentation for heritage buildings is one of the methods of preserving them as it provides a current record for the buildings. Digital records of heritage buildings can be used for future building rehabilitation, or be presented to the public to raise the awareness, increase tourism and decrease vandalism. This paper focuses on scanning object geometry factor to increase the quality of heritage’s façade point cloud. It optimizes the scanner locations and the scanner field of view to increase the point cloud quality and shorten the scanning time while guaranteeing a set of quality constraints for the point cloud. The quality constraints are based on the incidence angle between the scanned surface and the laser beam, and the max spacing between points. Three different multi-objective optimization algorithms are utilized: 1) genetic algorithm, 2) Jaya algorithm, and 3) particle swarm optimization to increase the quality. Optimization performance measures are adopted to compare the outputs of the optimization algorithms. A multi-criteria decision-making technique (Weighed sum model) is used to choose the optimum solution between the Pareto frontier solutions. Optimization algorithms minimize point cloud density and scanning time while assuring a required point spacing and max incidence angle by changing distance between laser scanner and scanned Facade, horizontal and vertical scan repetitions, and scanner different resolutions. The Jaya algorithm generates the most diversifiable optimal solutions and it is the fastest of the three algorithms considered. This research focuses on vertical building façade and future research will include the all types of Heritage façade. Omar Tosson Palace in Egypt is considered as a case study to demonstrate the use of the developed methodology and to illustrate its essential features.
