“…On the other hand, geographic information scientists also explore different types of 1:x (with x > 1 ) scaled data representations (e.g. by combing world-maps and globes (Yang et al 2018), or maps and diagrams in virtual space (Havenith et al 2019), where map-space and map user are separated so that users must bring themselves into a relationship with the information displayed in terms of a third-person perspective ( Fig. 1).…”

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.

This paper presents a novel immersive Virtual Reality platform, named ARGO3D, tailored for improving research and teaching activities in Earth Sciences. The platform facilitates the exploration of geological environments and the assessment of geo-hazards, allowing reaching key sites of interest (some of them impossible to be reached in person) and thus to take measurements and collect data as it can be done in the real field. The target audience of ARGO3D encompasses students, teachers and early career scientists, as well as civil planning organisations and non-academics. The overall workflow for real ambient reconstruction, processing and rendering of the virtual ambient is presented, as well as a detailed description of the VR software tools and hardware devices employed.

“…With big data tools, impacts can be explored across a whole region, rather than just one or two small localities. Instead of providing spreadsheets of uninspiring figures to illustrate the impact of, for example, urban transportation (e.g., https://movement.uber.com/explore/paris), road routing decisions in general [6], or different types of hazards [7], visualizations provide one version of the truth for all to use.…”

Big data have also become a big challenge for cartographers, as the majority of big data may be localized. The use of visual analytics tools, as well as comprising interactive maps, stimulates inter-disciplinary actors to explore new ideas and decision-making methods. This paper deals with the evaluation of three map-based visual analytics tools by means of the eye-tracking method. The conceptual part of the paper begins with an analysis of the state-of-the-art and ends with the design of proof-of-concept experiments. The verification part consists of the design, composition, and realization of the conducted eye-tracking experiment, in which three map-based visual analytics tools were tested in terms of user-friendliness. A set of recommendations on GUI (graphical user interface) design and interactive functionality for map makers is formulated on the basis of the discovered errors and shortcomings in the assessed stimuli. The results of the verification were used as inputs for improving the three tested map-based visual analytics tools and might serve as a best practice for map-based visual analytics tools in general, as well as for improving the policy making cycle as elaborated by the European project PoliVisu (Policy Development based on Advanced Geospatial Data Analytics and Visualization).
