The City

Olomouc, nowadays a city with 100,000 inhabitants, has always been considered as one of the most prominent Czech cities. It is a social and economical centre, which history started just about the 11th century. The present appearance of the city has its roots in the 18th century, when the city was almost razed to the ground after the Thirty years’ war and a great fire in 1709. After that, the city was rebuilt to a baroque military fortress against Prussia army. At the beginning of the 20th century the majority of the fortress was demolished. Character of the town is dominated by the large number of churches, burgher’s houses and other architecturally significant buildings, like a Holy Trinity Column, a UNESCO World Heritage Site. Aim of this project was to state the most suitable methods of visualization of spatial-temporal change in historical build-up area from the tourist’s point of view, and to design and evaluate possibilities of spatial data acquisition. There are many methods of 2D and 3D visualization which are suitable for depiction of historical and contemporary situation. In the article four approaches are discussed comparison of historical and recent pictures or photos, overlaying historical maps over the orthophoto, enhanced visualization of historical map in large scale using the third dimension and photorealistic 3D models of the same area in different ages. All mentioned methods were geolocalizated using the Google Earth environment and multimedia features were added to enhance the impression of perception. Possibilities of visualization, which were outlined above, were realized on a case study of the Olomouc city. As a source of historical data were used rapport plans of the bastion fortress from the 17th century. The accuracy of historical maps was confirmed by cartometric methods with use of the MapAnalyst software. Registration of the spatial-temporal changes information has a great potential in urban planning or realization of reconstruction and particularly in the propagation of the region and increasing the knowledge of citizens about the history of Olomouc.

Various widely available applications such as Google Earth have made interactive 3D visualizations of spatial data popular. While several studies have focused on how users perform when interacting with these with 3D visualizations, it has not been common to record their virtual movements in 3D environments or interactions with 3D maps. We therefore created and tested a new web-based research tool: a 3D Movement and Interaction Recorder (3DmoveR). Its design incorporates findings from the latest 3D visualization research, and is built upon an iterative requirements analysis. It is implemented using open web technologies such as PHP, JavaScript, and the X3DOM library. The main goal of the tool is to record camera position and orientation during a user’s movement within a virtual 3D scene, together with other aspects of their interaction. After building the tool, we performed an experiment to demonstrate its capabilities. This experiment revealed differences between laypersons and experts (cartographers) when working with interactive 3D maps. For example, experts achieved higher numbers of correct answers in some tasks, had shorter response times, followed shorter virtual trajectories, and moved through the environment more smoothly. Interaction-based clustering as well as other ways of visualizing and qualitatively analyzing user interaction were explored.

Crowdsroucing of emotional information can take many forms, from social networks data mining to large-scale surveys. The author presents the case-study of emotional mapping in Ostrava´s district Ostrava-Poruba, Czech Republic. Together with the local administration, the author crowdsourced the emotional perceptions of the location from almost 400 citizens, who created 4,051 spatial features. Additional to the spatial data there were 1,244 comments and suggestions for improvements in the district. Furthermore, the author is looking for patterns and hot-spots within the city and if there are any relevant linkages between certain emotions and spatial locations within the city.

Visualization Techniques

3D visualization is the process of displaying spatial data to simulate and model a real three dimensional space. Using 3D visualization, Geomatic professionals are enabling pipeline engineers to make better decisions by providing an increased understanding of potential costs earlier in the design process. This paper will focus on the value of visualizing Digital Elevation Model (DEM) data through the use of hillshades and imagery-draped 3D models. From free online DEM data to high resolution Light Detection and Ranging (LiDAR) derived DEM data, the increased availability allows for a broader use of 3D visualization techniques beyond 3D analysis. Of the numerous sources available, two DEM sources will be discussed in this paper, the free low resolution DEM (CDED Level 1) and the more costly but higher resolution LiDAR based DEM. Traditional methods of evaluating potential locations for route and facilities involved a significant cost for ground truthing. Through the use of 3D visualization products, multiple potential locations can be examined for suitability without the expense of field visits for every candidate site. By focusing on the selected candidate locations using a visual desktop study, the time and expense of ground truthing all of the potential sites can be reduced significantly. Exploiting the visual value of DEM permits a productive and cost efficient methodology for initial route and facility placement on hydrocarbon projects.

There is money to be made in the financial industry. Academics, under pressure to exhibit relevance, are happy to point to their consultancies in the City as evidence of their value in the market, and the industry has shown a notable ability to recruit the brightest and best from our Universities. These observations should not obscure the profound scientific challenges posed by the area of finance. The area has both stimulated and benefited from advances in a range of mathematical sciences, most obviously probability, differential equations, optimization, statistics and numerical analysis. One thinks, for example, of Bernoulli’s resolution, in the 18th century, of the St Petersburg Problem through his introduction of a logarithmic utility, of Bachelier’s description, at the turn of this century, of the stochastic process we now call brownian motion, of Kendall’s investigation, forty years ago, of the statistical unpredictability of stock prices, and of the current enormously fertile interaction between economics and mathematics centred around martingale representations. Looking to the future, some of the mathematical ideas originally motivated by statistical mechanics, and since used to model the large-scale telecommunication networks upon which the financial industry relies, may also provide insight into the very difficult problems that arise in economics concerning interacting systems of rational agents.

3D City Modelling

Abstract. The smart city concept may aid in improving the city management, enhance the efficiency and thus increase the effectiveness of the city, where it is mainly focused on both information and technologies. This concept appears to be applicable for a smaller area such as university campus. Based on this idea, this research tries to implement the 3D smart campus for Universiti Teknologi Malaysia (UTM). This is an initial research towards a real implementation of 3D smart campus and conceivably 3D smart cities. This research focuses on the development of UTM smart campus by using 3D city modelling. The QGIS software was used to develop the 3D models. Then, the 3D model is viewed in a web browser for better 3D visualization and navigation. Furthermore, the results show that the 3D developed models for UTM smart campus can be a reliable platform to manage the spatial query and viewing the attributes of UTM campus buildings and facilities. This can be seen beneficial to the physical future development of the UTM campus area.

The article deals with the specific urban and suburban spaces where landscape design and garden art were confronted with existing or later disappearing fortification system. It analyses structures related to the landscape architecture from the baroque and classical times to the era of the pseudohistorical style, from the end of the 17th century to the end of the 19th century, with special interest devoted to the less known historical forms of the 18th century and their development. Using detailed historical maps and plans, the research reveals elements of landscape architecture in smaller or larger scale of several types – gardens close to the city walls, tree plantings and gardens on the fortification bastions, gardens and promenade alleys under them on the glacis or private gardens on the surrounding grounds, that were still influenced by the existence of the fortification system.Two historically important Moravian cities were used here as an example – Brno and Olomouc, where main types of green spaces (near the walls on their both sides) and several possible ways of their development were followed and analysed, and specific types of compositional and spatial development were defined. These could be understood as basic ‘evolution types’ specific for central European cities in general, and can be found in variations in other cities and towns in this region.

<p><strong>Abstract.</strong> In the cultural heritage field, several specialists like archaeologists, architects, geomaticians, historians, etc. are used to work together. With the upcoming technologies allowing to capture efficiently data in the field, to digitize historical documents, to collect worldwide information related to the monuments under study, the wish to summarize all the sources of data (including the knowledge of the specialists) into one 3D model is a big challenge. In order to guarantee the reliability of the proposed reconstructed 3D model, it is of crucial importance to integrate the level of uncertainty assigned to it. From a geometric point of view, uncertainty is often defined, quantified and expressed with the help of statistical measures. However, for objects reconstructed based on archaeological assumptions, statistical measures are not appropriate. This paper focuses on the decomposition of 3D models into levels of uncertainties (LoUs) and on the best way to visualize them through two case studies: the castle of Kagenfels and the Horbourg-Wihr Castellum, both located in Alsace, France. The first one is well documented through still ongoing excavations around its remains, whereas the second one disappeared under the urbanization of the city. An approach enabling, on the 3D models, not only to quantify but also to visualize uncertainties coming from archaeological assumptions is addressed. Finally, the efficiency of the approach for qualifying the proposed 3D model of the reconstructed castle regarding its reliability is demonstrated.</p>

In this paper, the flow of water in several elements of the water supply system of the city of Apamea is simulated. The studied elements were used at the end of the 6th century AD (Byzantine period). These simulations allow for the analysis of the water supply system from a modern point of view, in terms of water flow rate, energy loss, etc. This analysis provides a quantitative description of the water supply system of the city, supplementing the field observations.

The article analyzes the first stages of studying the archaeological sites of the Kashkadarya oasis from a historical point of view. Beginning in the 18th century, Europeans began to record information about the Kashkadarya oasis. Their main focus is on highlighting the lifestyle of the population, as well as information on historical monuments. In particular, in memoirs, reports and brochures, A. Burns, N. Khannykov, V.V. Bartold, N. Maev, V. Krestovsky, B. Litvinov, D. Logofet, A. Validov, I. Kastane, L. Zimin, you can get a lot of information on this topic. Despite this, the first studies were mostly brief. Most importantly, the attention of architects and art critics is focused on the history of architectural structures in Shakhrisabz, built during the reign of Amir Temur and the Temurids. However, attempts to shed light on the history of the cities of Karshi and Shakhrisabz based on written sources consisted in a collection of the first archaeological observations, historical artifacts and manuscripts. Noteworthy is the information written by N. Khannykov, V.V. Bartold, N. Mayev. Subsequent studies also made extensive use of their memoirs. B. Litvinov's information about the Kashkadarya oasis was supplemented by his drawings. According to Logofet, the history of the city of Shakhrisabz is emphasized, and archaeological excavations show that its history goes back two thousand years. Logofet pays great attention to the medieval history of Karshi, cites various historical sources. It is important for I.Kastana and L.Zimin to describe the archaeological monuments preserved in the vicinity of Karshi from the point of view of that period and compare them on the basis of ancient and medieval written sources.

Postmodernism is a mid-20th-century response to 18th-century Enlightenment rationality. As a movement that developed across a diverse range of disciplines, it is not so much defined by a distinct chronology but rather is predicated on a recognition of the past and has come to represent a way of operating. The late Italian semiotician and writer Umberto Eco argued from an ideological point of view that every period in history has had its postmodernism. Architect and critical theorist Charles Jencks further polemicized postmodernism as a specific form of cultural resistance. In his view, postmodernism operates as a communicative set of values to address the needs of a society, and he cites architecture’s response to the pressing need for mass housing and large-scale urban redevelopment as an example of postmodern innovation. Inspired by postmodernism as a critical movement in the arts, architecture, and philosophy, postmodern curriculum similarly works to reject the universalizing ideals of modernity. It shares Jencks’s polemic stance and would have us reimagine the literal and metaphorical bricks and mortar of schools, colleges, and universities to advance a broader understanding of curriculum with the aim of addressing the need to provide fair and equitable access to education. The postmodern notion that the past has everything to do with the present is central to decolonizing efforts aimed at acknowledgment and reconciliation of the devastating and oppressive ends of curriculum as institutions. For example, government-sponsored residential schools in Canada and the United States stand as a glaring example of the abject failure of modern education to embrace the communicative ideals of postmodernism in its response to First Nations people. Postmodern curriculum is committed to a decentering and challenging agenda aimed at exposing and undermining master narratives of truth, language, knowledge, and power. Dynamic and responsive, postmodern curriculum’s holistic and ecological approach to education works to dissolve the artificial boundary between the outside community and the classroom to celebrate and honor the interconnectedness of knowledge, experience, international and local communities, the natural world, and life itself.
