Na trilha das metodologias ativas, a simulação de formas e processos espaciais a partir da Realidade Aumentada se apresenta como uma nova possibilidade de ensino-aprendizagem. Neste estudo, é feita uma análise da efetividade do uso da interface tangível SARndbox no ensino de Geomorfologia para o ensino médio. Trabalhou-se com 54 alunos do 1° Ano do Ensino Médio de uma escola pública da Região Metropolitana do Recife. Esses participaram de uma atividade de identificação de feições geomórficas a partir da visão 2D e 3D. A condução da atividade estruturou-se em três etapas: 1. Aula expositiva dialoga e atividade diagnóstica; 2. Interação com a SARndbox e 3. Reaplicação da atividade diagnóstica. Apesar de sutil, houve melhora na taxa de acerto das respostas. É necessário analisar criticamente estas novas tecnologias, buscando-se sempre adaptá-las a realidade da sala de aula.

2-dimensional and 3-dimensional representations have been used in various physical, virtual, and geovisual surface models of the earth - to improve spatial thinking skills. Physical models such as relief maps have been shown to enhance understanding of topographic maps, helping to understand the relationship between 2D representations and 3D objects. Virtual models can support spatial learning, for example, by viewing objects at various angles, by providing an environmental context. This model makes it possible to combine physical models’ interactive benefits with virtual tools’ flexibility and diversity. The term geovisual is an overlay depiction of information scanned through a sensor, processed by a computer. Subsequently, the data obtained are presented to the media so that it is like the real world. It has been built and used in this Tangible research Landscape, which is a real-time geovisual system integrated into a computer connected to a 3D sensor, projector, and supported by GRASS GIS [1]. This geovisual system is then applied for modeling terrain 3-D terrain physically through media, scanned through sensors to a computer, and used to analyze the environment with various effects and graphical simulations. The initial model produced is topography from aerial photographs and DEM from LiDAR, which has a spatial resolution of up to 0.4 meters showing physical processes such as contour lines and water flow, and sediment transportation can be well visualized.

To create more sustainable and livable cities, researchers work on different topics. In this context, bicycles have an important positive effect on people living in urban areas since they provide not only relief of traffic congestion but also enhance citizens’ health. The finding suitable locations of bicycle sharing system stations and bicycle lanes are attracted attention because they have a huge contribution to providing bicycles are part of everyday life. The aim of this study is to propose a workflow that combines GIS and MCDM methods to determine locations of bicycle sharing system stations and bicycle lanes together. MCDM methods are used to identify which criterion more effective than others since different factors affect the location selection process. Weights of criteria are obtained using AHP, FAHP, and BWM while TOPSIS is applied to rank alternative locations. To provide a more useful and sharable solution, site selection model is prepared in QGIS which is a widely used open source GIS software. First, three different suitability index are obtained using weights that came from MCDM methods. After, average analysis is applied to these suitability indexes so as to increase the reliability of the result. Furthermore, three different scenario applications that take into consideration whether study area has bicycle sharing system station and bike lane currently are implemented in this study. Various alternative locations for bicycle sharing system station and bike lane are proposed in order to support urban planning studies.
... A similar application is the "tangible landscape" (https://tangible-landscape.github.io) (Petrasova et al. 2015).

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 use of immersive technologies and introduce the spectrum of terminology on virtual, augmented and mixed reality, as well as proposed research concepts in geographic information science and beyond. We finish with an overview of “dashboards”, which are used in visual analytics as well as in various immersive technologies. We believe the chapter covers important aspects of visualizing and interacting with current and future Digital Earth applications.
... In that way, tasks about height judgment, natural limitations or visibility assertions of locations are difficult to accomplish, as learners have to reconstruct and reason for them mentally ( Li et al., 2017). Another form of maps, tangible 3D physical maps, have also played and continue to play a major role in contemporary cartography (Buchanan and Tschida, 2015;Petrasova et al., 2015). Tangible physical maps based on the traditions in cartography and enhanced by new digital forms of interaction complement and advance digital cartography presented in screens. ...

Purpose
Tangible physical maps which are enhanced by new digital forms of interaction can become an invaluable asset for learning geography in an embodied way. The purpose of this work is to evaluate an interactive augmented three-dimensional (3D) tangible map on which students interact and travel with their fingers.
Design/methodology/approach
A total of 58 fourth-grade students from eight elementary schools participated in the study. The participants played with the FingerTrips environment in 24 sessions and in groups of two or three. Each session lasted for about 20-25 min. After completing the interactive game, the students answered a questionnaire concerning their attitudes toward the tangible environment and participated in a short interview.
Findings
Students’ responses revealed that FingerTrips managed to transform the experience of meeting new places, understanding spatial relations and learning geography. Students supported that such an approach is closer to their interactive experiences and expectations, and exploits embodied learning affordances to achieve enjoyable learning. Students identified their finger-based trips as an effective and intriguing static haptic guidance that helped them learn more effectively.
Originality/value
The specific approach has two distinctive characteristics. First, a new interaction style on the map is suggested, the use of trips with fingers. Students have to follow predefined engraved paths on the 3D terrain to sense distances and changes in altitude and “touch” the topology asked to understand and explore. Second, it is examined whether a low fidelity interactive 3D terrain, which can be easily reconstructed and reprogrammed by primary school students, can become a useful canvas for learning geography.

Geodesign method and tools are extensively used for collaborative decision making focused on different fields such as transportation, land use, and landscape and has been applied in various places around the world. Nowadays, Augmented Reality (AR), Virtual Reality (VR) and more recently AR sandbox are increasingly becoming very popular particularly as a pedagogical tool. This research aims to investigate whether an AR sandbox could enhance the understanding of people around the development of design proposals and their impacts. We explored if AR sandbox could be implemented in a collaborative geodesign workflow. We reported an experiment where people were asked to build new trails using the sandbox and how the trails they designed were integrated with a larger design. Results explore opportunities and limitations of implementing AR sandbox in a collaborative geodesign workflow based on the experiment in this paper. Our AR sandbox experiment revealed a wide range of benefits to participants in the trail planning and to the geodesign structure.
... The methods to visualize digital terrain modeling results have not kept pace with the rapidly evolving computational resources and the availability and use of fine resolution DEMs which cover large areas. The map generalization projects funded as part of the NED research program in the U.S. [22] and the new tangible geospatial modeling system proposed by Petrasova et al. [23] may help to fill this gap. ...
This paper summarizes the current state-of-the-art in geomorphometry and describes the innovations that are close at hand and will be required to push digital terrain modeling forward in the future. These innovations will draw on concepts and methods from computer science and the spatial sciences and require greater collaboration to produce “actionable” knowledge and outcomes. The key innovations include rediscovering and using what we already know, developing new digital terrain modeling methods, clarifying and strengthening the role of theory, developing high-fidelity DEMs, developing and embracing new visualization methods, adopting new computational approaches, and making better use of provenance, credibility, and application-content knowledge.
... During last decades, extensive forest fires have spread in Southern Europe, and they are registered in Serbia as well (Marković et al., 2016). Whether of natural or anthropogenic origin, forest fires are a potential risk both for ecosystems and human settlements and this risk can be decreased and managed by tracking the weather, controlling fires to limit available fuel and creating firebreaks (Petrasova, Harmon, Petras, & Mitasova, 2015). ...
