Abstract Modern hardware and software innovations in the field of virtual reality (VR), such as VR headsets and accessible game engines, allow cartographers to create 3D environments which can be experienced from the ego perspective in real time and with a simulated illusion of physical presence (immersion) in the virtual representation. The new immersive experience of these virtual environments requires new ideas on how to present and orchestrate geographical information for the benefit of planning applications. This paper intends to present examples how VR-based 3D environments use can be enriched (based on the game engine Unreal Engine 4) to support the district development of a restructured post-industrial area. A VR model of a representative former industrial area in the German Ruhr district which was revitalized and part of a large urban transformation programme (IBA Emscher Park), serves an example. Today, the area of “Zeche Holland” in Bochum-Wattenscheid is characterized by a mix of residential and commercial uses. The area is used as a leisure route for locals and tourists, with an old winding tower as an important urban landmark in its centre. VR techniques allow to transport additional spatial information which cannot be experienced when visiting the real physical area. This paper addresses the potential of immersive VR environments representing a multifaceted and redeveloped area for planning and related usage scenarios. It shows how peculiarities of game engine-based VR can help to extend the immersive (3D) experience of geographic information.

AbstractModern game engines like Unity allow users to create realistic 3D environments containing terrains as well as natural and artificial objects easily and swiftly. In addition, recent advances of game engine capabilities enable effortless implementation of virtual reality (VR) compatibility. 3D environments created with VR compatibility can be experienced from an egocentric and stereoscopic perspective that surpasses the immersion of the ‘classical’ screen-based perception of 3D environments. Not only game developers benefit from the possibilities provided by game engines. The ability to use geospatial data to shape virtual 3D environments opens a multitude of possibilities for geographic applications, such as construction planning, spatial hazard simulations or representation of historical places. The multi-perspective, multimodal reconstruction of three-dimensional space based on game engine technology today supports the possibility of linking different approaches of geographic work more closely. Free geospatial data that can be used for spatial reconstructions is provided by numerous national and regional official institutions. However, the file format of these data sources is not standardized and game engines only support a limited number of file formats. Therefore, format transformation is usually required to apply geospatial data to virtual 3D environments. This paper presents several workflows to apply digital elevation data and 3D city model data from OpenStreetMap and the Open.NRW initiative to Unity-based 3D environments. Advantages and disadvantages of different sources of geospatial data are discussed. In addition, implementation of VR compatibility is described. Finally, benefits of immersive VR implementation and characteristics of current VR hardware are discussed in the context of specific geographic application scenarios.

The area of Bagnoli (Gulf of Naples, central Tyrrhenian Sea) has been heavily exposed to pollution for over a century due to the presence of industrial sites along its coastline. The aim of this study is to analyze contaminant concentrations (i.e., heavy metals and hydrocarbons) in seabed sediments through a statistical multivariate approach. Multivariate methods permit us to describe the pollution dynamics affecting the area and distinguish between anthropogenic and natural pollution sources. Additionally, the association between contamination patterns and the wave climate characteristics of the gulf (i.e., wave period, direction, height, power, and energy) is investigated. The study confirms that the main contamination source in the Bagnoli bay is anthropogenic activities (i.e., former steel plant and sewage discharges) for the majority of investigated pollutants. It also provides evidence, however, for the potential co-existence of multiple anthropogenic and geogenic sources of arsenic and other metals that may be originating also from the water-rock interaction and submarine volcanic emissions in the Phlegraean area.

Brownfields are remnants of the functional and spatial transformations of urban areas in Poland. They are particularly abundant in old industrial districts, based on coal mining and metallurgy. The aim of this study is to identify the transformation directions and functional changes of brownfields in the former Upper Silesian Industrial Region in southern Poland, which has evolved into the Górnośląsko-Zagłębiowska Metropolis (GZM) through the process of socio-economic transformation. The study makes use of the χ2 test of independence and Cramer’s V as a post-test, and the method of in-depth interviews. The results indicate that the most popular new functions of post-industrial sites are production and services. When we consider large brownfields such as, in particular, disused mine dumps, dumping sites, settling ponds and workings, the most popular new form of land use is green spaces. Moreover, the study shows that the size of brownfields impacts their new forms of land use.

The aim of this article is to present spectacular examples of reclamation and development of post-industrial sites, carried out in Poland in the 1920s and 1950s, with emphasis on their recreational function. Examples include a park built between 1889 and 1920 by Wojciech Bednarski in the valley of the former quarry in Podgórze, now the right-bank district of Krakow, and “General Jerzy Ziętek Provincial Park of Culture and Recreation”, now called “the Silesia Park”, created in the 1950s on degraded post-industrial land located within the borders of three cities: Chorzów, Katowice and Siemianowice Śląskie. Both parks are examples of reclaiming brownfield sites for recreational use in order to create attractive leisure spaces. They have become a model and point of reference for other park planning projects in Poland. Their spatial and functional design is exceptionally timeless. The study is mainly based on a review of the literature of the subject.

"Geographic information system (GIS) collects various kinds of data based on the geographic relationship across space." Data in GIS is stored to visualize, analyze, and interpret geographic data to learn about an area, an ongoing project, site planning, business, health economics and health-related surveys and information. GIS has evolved from ancient disease maps to 3D digital maps and continues to grow even today. The visual-spatial mapping of the data has given us an insight into different diseases ranging from diarrhea, pneumonia to non-communicable diseases like diabetes mellitus, hypertension, cardiovascular diseases, or risk factors like obesity, being overweight, etc. All in a while, this information has highlighted health-related issues and knowledge about these in a contemporary manner worldwide. Researchers, scientists, and administrators use GIS for research project planning, execution, and disease management. Cases of diseases in a specific area or region, the number of hospitals, roads, waterways, and health catchment areas are examples of spatially referenced data that can be captured and easily presented using GIS. Currently, we are facing an epidemic of non-communicable diseases, and a powerful tool like GIS can be used efficiently in such a situation. GIS can provide a powerful and robust framework for effectively monitoring and identifying the leading cause behind such diseases.  GIS, which provides a spatial viewpoint regarding the disease spectrum, pattern, and distribution, is of particular importance in this area and helps better understand disease transmission dynamics and spatial determinants. The use of GIS in public health will be a practical approach for surveillance, monitoring, planning, optimization, and service delivery of health resources to the people at large. The GIS platform can link environmental and spatial information with the disease itself, which makes it an asset in disease control progression all over the globe.

Ruhr District

<p>The Ruhr district meets the necessary elements to carry out geothermal projects due to its geothermal potential and demand, as it is a densely populated industrial area. Currently, there are projects for direct use, whereas projects for electricity generation are planned. The latter, due to greater depths, reservoir enhancement techniques are required in some cases. This may increase the associated seismic risk which should be elaborated in detail.</p><p>With available data, a three-dimensional geological and structural model was created. The shallower parts have been widely studied and documented by mining activity in the Ruhr region during the last century.  Below a depth of 1 km, data are scarce, and uncertainties increase. The full elastic wavefield emitted by a realistic seismic source has been simulated using a finite differences scheme and the derived geological model. The elastic properties were estimated with well data. The source has common characteristics of real seismic events in the area.</p><p>The wave propagation simulations let us analyze the seismic response with different sources and velocities models. Three cases are considered, two seismic events with distinct depths based on real events. The third case is based on the proposed location of a deep geothermal project.</p><p>Especially for the case with the deeper source, the areas with relatively high amplitudes of displacement correlated with structural features of the model. Applying the imaging condition of maximum energy density allows us to define zones with a potentially increased seismic risk that should be monitored more closely.</p>
