“…The visualization of existing and future natural environments is becoming more important for decisionmaking, as well as for recreational and scientific communication, as it considerably helps to better understand the various spatial relations in an environment [1,2]. This is an important topic for ecologists who are focusing on developing ecological models that can predict how an environment develops in the future.…”

Interactive 3D visualization of natural environments can help ecologists, policy makers and the broad public in general to better understand, promote and protect both existing and developing environments. The creation and exploration of virtual worlds can be very helpful for this purpose. However, current techniques are not able to generate sound complex natural environments from ecological data for the use of interactive webbased visualizations. In this thesis, we approach the challenge of developing and interactively visualizing in real time ecologically accurate and visually convincing models of complex natural environments over the web. For this, we propose a framework that (i) is able to combine landscape maps and ecological statistical data, translating them to an ecologically sound plant distribution, and (ii) creates a detailed 3D representation of the natural environment and provides for its fully interactive visualization in real-time over the web. The main contributions of this research are a procedural method to generate complete and sound natural environments and a web-based renderer that is able to real-time visualize complex natural environments with their high density and variability of individual organisms. The vegetation model combines and improves techniques from procedural ecosystem generation and neutral landscape modeling. It is able to generate diverse ecological sound plant distribution directly from landscape maps with statistics about coverage and patchiness of plant species. The visualization model uses several existing level-of-detail and illumination techniques to achieve interactive frame rates and improve realism. Validation of the results with ecology experts led us to conclude that our framework provides convincing interactive visualizations of large virtual natural environments.iii

“…One school of thought is that 3D models can assist users to orientate themselves in a familiar environment and can make understanding landforms easier than with traditional 2D representations Smallman et al, 2007;Wood et al, 2005;van Lammeren et al, 2010). Another school of thought posits that 3D representations will lead to cognitive overload, and that this might outweigh the benefits (Bleisch and Nebiker, 2008;Richards and Taylor, 2015;Métral et al, 2012).…”

ABSTRACT:Informal settlements are a common occurrence in South Africa, and to improve in-situ circumstances of communities living in informal settlements, upgrades and urban design processes are necessary. Spatial data and maps are essential throughout these processes to understand the current environment, plan new developments, and communicate the planned developments. All stakeholders need to understand maps to actively participate in the process. However, previous research demonstrated that map literacy was relatively low for many planning professionals in South Africa, which might hinder effective planning. Because 3D visualizations resemble the real environment more than traditional maps, many researchers posited that they would be easier to interpret. Thus, our goal is to investigate the effectiveness of 3D geovisualizations for urban design in informal settlement upgrading in South Africa. We consider all involved processes: 3D modelling, visualization design, and cognitive processes during map reading. We found that procedural modelling is a feasible alternative to time-consuming manual modelling, and can produce high quality models. When investigating the visualization design, the visual characteristics of 3D models and relevance of a subset of visual variables for urban design activities of informal settlement upgrades were qualitatively assessed. The results of three qualitative user experiments contributed to understanding the impact of various levels of complexity in 3D city models and map literacy of future geoinformatics and planning professionals when using 2D maps and 3D models. The research results can assist planners in designing suitable 3D models that can be used throughout all phases of the process.

“…Recent studies focus primarily on the visualisation effectiveness of digital decision-making tools in participatory planning processes (Bailey & Grossardt, 2010;Gill, Lange, Morgan, & Romano, 2013;Schroth, Hayek, Lange, Sheppard, & Schmid, 2011), their usability in terms of user experience (De Boer, Breure, Spruit, & Voorbij, 2011;Ruotolo et al, 2013) or the affective appraisal of 3D visualisations and human-computer interaction (van Lammeren, Houtkamp, Colijn, Hilferink, & Bouwman, 2010). Dee (2004) suggests further research into critical visual studies that looks at effectiveness and usability in terms of the convergence between image intent and image reception.…”

The semiotics of landscape design communication: towards a critical visual research approach in landscape architecture

et al. 2016

View full text Add to dashboard Cite

In landscape architecture, visual representations are the primary means of communication between stakeholders in design processes. Despite the reliance on visual representations, little critical research has been undertaken by landscape architects on how visual communication forms work or their socio-political implications. In this theoretical paper, we argue that such research is of great importance. We explain how concepts of visual and critical social theory such as visual semiotics, simulacra and simulation, and power/knowledge can be used to critically reflect on landscape architectural representations. We further propose to study these representations at different stages of meaning-making by using visual methodologies such as visual discourse analysis, iconographical content analysis and social semiotic analysis. We conclude that these research approaches have the potential to explain issues such as dominant power structures, miscommunication between participants, and visual path-dependencies during landscape design processes.
