Using unmanned aerial vehicle data to assess the three-dimension green quantity of urban green space: A case study in Shanghai, China
Urban green space (UGS), which plays an important role in reducing the problems associated with urbanization, needs to be evaluated by metrics. Three-dimension green quantity (3DGQ), a quantitative index that measures the crown space occupied by a growing plant, is often used to evaluate the extent, and the environmental and climatic benefits of UGS. The objective of this study was to measure the 3DGQ of Paotaiwan Wetland Park (PWP) in Shanghai, China. Implementation of the 3DGQ index was supported by remote sensing (RS) images taken by an unmanned aerial vehicle (UAV). The 3DGQ calculations for 100 species of trees were used to calculate the 3DGQ of the UGS in PWP. The environmental and climatic benefits of UGS in PWP were also evaluated. The 3DGQ for the whole PWP was 668,624.13 m3. The mixed woods in the PWP annually absorbed 1,635.57 t CO2, 2.03 kg SO2, 735.48 t dust, and 2,254.49 t of O2. There was 367.74 t of diurnal transpiration. The lowered temperature of the PWP in the transpiration scope at 100 m altitude was 1.8 °C. The use of a UAV to assess UGS could help planners and policy makers to improve the environmental and climatic benefits of UGS.
In this newly published open source paper, Robert Newell, Ann Dale and Celia Winters at Royal Roads University in BC investigated the efficiency and effectiveness of interactive data visualisations in the commmunication of building energy production and consumption. Two visualizations were built that held contrasting features: an abstract, static visualization built in the form of a time-series graph and a dynamic, interactive visualization with a ‘picturesque’ design. The results indicate that the interactive visualization held higher potential for drawing in and maintaining audience interests, whereas the static visualization was more useful for users wishing to gain a more detailed understanding of the data. These findings suggest that both types of visualizations have complementary strengths, and collaboration between trans-disciplinary research teams and graphic artists can lead to visualizations that attract diverse audiences and facilitate different information needs and access.
In addition to the most interesting research, the paper itseld includes some interactive PDF features inherently picking up the topic of interactivity in its own presentation.
In this fully open access paper, Michael Getzner, Barbara Faerber and Claudia Yamu compare 2D versus (stereoscopic) 3D landscape visualisations of different landscape scenarios in the Alps. Although there have been previous studies of landscape visualizations of alpine scenarios, I found that this paper is adding a couple of particularly new perspectives: a) the use of stereoscopic (anaglyph) visualisations and b) the link to the economic valuation of different landscapes through the participants. It should be said that this study like many others was conducted with students. However, I think it provides the legitimization to use landscape visualisations for other studies on the economic valuation of such landscapes.

This is the first issue of the new Journal of Digital Landscape Architecture. JoDLA addresses all aspects of digital technologies, applications, information, and knowledge bases in research, education, and practice pertaining to landscape architecture and related fields. The journal publishes original papers that address theoretical and practical issues, innovative developments, methods, applications, findings, and case studies that are drawn primarily from work presented at the annual international Digital Landscape Architecture conference. Its intent is to encourage the broad dissemination of these ideas, innovations, and practices.
This issue of the Journal of Digital Landscape Architecture, 1-2016, presents contributions from the 17th annual conference at the Technical University, Istanbul, Turkey, (June 1 to 3, 2016) covering five broad themes:
• Systems Thinking in Landscape Design Processes
• Landscape Visualization and Analysis
• Geodesign Concepts and Applications
• Mobile Devices for Geodesign
• Teaching Methods in Digital Landscape Architecture
Ass. Prof. Dr. Mark Lindquist, who completed his PhD at the Department of Landscape at the University of Sheffield, just published a paper in Landscape and Urban Planning summarizing his findings about the contribution of sound to the perception of landscape visualisations.
His key research findings are:
- Sound significantly alters perceptual responses to 3D landscape visualizations.
- Realism and preference are moderated by congruency of visual and sound content
- Eye level Google Earth visualizations receive low realism ratings.
- Aural-visual survey data collected via the web is comparable to laboratory data.
- Sound and visuals that are spatiotemporally congruent are recommended for simulations.

Special issue released: The April 2015 issue of Environmental Impact Assessment Review, edited by Lorenz Hilty and Bernd Page, provides an overview of ICT-based approaches to facilitate the assessment of renewable energy solutions.
Recent advances in landscape visualization have dramatically increased our ability to portray past, present, and future conditions across a range of scales from site to region, altering the ways in which people perceive their environments and influencing changes in social and cultural practices. While landscape architects and planners have long employed representational methods, the proliferation of new digital technologies for visualization is rapidly outpacing the theoretical grounding needed to meaningfully guide design and planning outcomes. This special issue attempts to bridge this practice–theory gap by bringing together diverse contemporary practices, methods, and theoretical perspectives in order to build a shared understanding of the relationships between visualization techniques and the knowledge they produce.

Special Issue: Critical Approaches to Landscape Visualization

I am excited to present the following research paper in Landscape and Urban Planning because it summarizes the work my colleagues and I put into my favorite research project, the Kimberley Climate Adaptation Project KCAP. It was very rewarding working closely with the local community, visualizing different development scenarios and their interactions with climate change impacts. Great to see that about 70 recommendations from the original visioning process were adopted in various policy documents and a dozen actually implemented. The paper looks in more detail at one of the implemented mitigation measures, a flood retention area along the river that leads through Kimberley.

This study synthesizes two evaluations of a local climate change planning process in a rural town in British Columbia (Canada), which was supported through landscape visualizations. First, the impact of the visualizations, based on scientific environmental modeling and presented in three different presentation formats, verbal/visual presentation, posters and a virtual globe, was evaluated with regard to immediate impacts during the process. Second, the long-term impacts on decision-making and actual outcomes were evaluated in a retrospective evaluation 22 months after the end of the initial planning process. Two results are highlighted: according to the quantitative pre-/post-questionnaires, the visualizations contributed to increased awareness and understanding. Most importantly, the retrospective evaluation indicated that the process informed policy, operational and built changes in Kimberley, in which the landscape visualizations played a role. The post interviews with key decision-makers showed that they remembered most of the visualizations and some decision-makers were further using them, particularly the posters. The virtual globe seemed to be not a “sustainable” display format suitable for formal decision-making processes such as council meetings though. That may change with the further mainstreaming of visualization technologies or mobile devices. Until then, we recommend using display formats that can be re-used following a specific planning event such as an Open House, to ensure on-going support for effective decision-making over the longer-term.
• Visualizations in a climate change planning process were assessed as very helpful by local stakeholders and residents.
• Visualizations presented in a virtual globe facilitated understanding and increased awareness during an open house.
• 22 months later most decision-makers still remembered or used the visualizations.
• Visualizations embedded into process informed policy, operational and built changes.
• Although the virtual globe presentation format was effective during the process it was less so in the long term.
