Last week, the Social Mobilisation for Climate Solutions Research Workshop took place at the Peter Wall Institute at the University of British Columbia. The workshop started with the “Changing Perceptions of Climate Change through Community Action” public sessions by Rob Hopkins (Transition Network), Elke Weber (Columbia University) and Stephen Sheppard (University of British Columbia). The event can be watched as webcast recording at http://www.socialmobilisation.pwias.ubc.ca.
After a number of workshop sessions, the series closed with a demo session, sponsored by GRAND. The DIGITAL MEDIA DEMO SESSION featured tools from leading local developers and academics who are advancing digital tools to communicate and mobilize meaningful action on issues of environmental sustainability and climate change.
Demo stations and presenters included:
Visualizing Landscape Architecture
I would like to draw your attention to a new book by Prof. Dr. Elke Mertens about visualization in landscape architecture. The book is very well presented by Birkhäuser, a publisher famous for his excellent books about architecture, and gives a great overview of various visualization techniques in landscape architecture. Please note that the book is available in English and German. The following is a quote from the Amazon description of the English version:
“We don’t sell gardens; we sell images of gardens.” This observation on the part of a landscape architect makes it clear just how important it is that a design be effectively communicated to the community, clients, and the public. Drawings, models, simulations, and films communicate the designers’ proposed ideas and solutions, but they also convey their attitude toward the use of nature and the environment. With myriad possibilities – including computer programs as well as hand drawings and models, which continue to be widely used – and strong competition in the field, there is now a huge variety of visual representations, with agreed-upon rules but also a great deal of freedom. In three large sections, this books sifts through the currently commonplace and available techniques and evaluates them in terms of their informative value and persuasive power, always illustrating its points with analysis of examples from international firms. An introductory look at the development thus far is followed by a systematic presentation of modes of representation in two, three, and four dimensions – in the plane, in space, and in the temporal process. The second section deals with the sequence within the workflow: from the initial sketch through concept and implementation planning all the way to the finished product. The third section deals with the strategic use of visualizations in the context of competitions, future schemes, and large-scale landscape planning. The focus in this section is not on the familiar use of the relevant techniques, but rather on the methods and forms of visual representation in contemporary landscape architecture.”
Major adaptation and mitigation
Funded by the Swiss National Science Foundation SNSF, and in collaboration with the Collaborative for Advanced Landscape Planning (CALP), particularly Ellen Pond, the City of Kimberley, and the Columbia Basin Trust (CBT), I analysed the benefits and limitations of interactive virtual globes for stakeholder engagement in climate related scenario planning over the last 12 months. The results have now been published as SNSF report and can be downloaded here.
Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110m scales. “Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software.”
Natural Earth Vector comes in ESRI shapefile format, Natural Earth Raster comes in TIFF format with a TFW world file, all Natural Earth data use the Geographic projection, WGS84 datum.
Unfortunately, only zip-File Download and no OGC Web Feature or Web Raster service is provided.
Microsoft Photosynth is a photogrammetric software that creates 3d buildings from multiple photos, e.g. shot by random tourists. Our colleagues from the urbandigital blog are very much in favour of Photosynth and see great potential in it for urban visualization or as a kind of 3d scanner. Now, Microsoft has taken the logic next step and integrated Photosynth with Bing 3D. It may be criticized that the Microsoft approach requires Silverlight which is still not standard. However, Bing users can now create buildings automatically from photos whereas Google Earth users are modeling their content in Sketchup. It will be very interesting to test both approaches in comparison and to see which one will finally find more users.
Another interesting approach by Microsoft is mentioned by Chris Dannen in the Fast Company blog: In the long-term, Microsoft wants to extract semantic information automatically from the user-generated photos. In this point, Microsoft meets latest research in photogrammetry, e.g. in the “Nachwuchsgruppe der Volkswagen Stiftung” in cartography at the University of Hanover, where the automatic extraction of facades from photos is researched.
With regard to landscapes, vegetation is still not an issue - neither for Google nor for Microsoft. How about the automatic extraction of vegetation information from photos? There is a lot research about the recognition of vegetation in orthophotos - how about linking this to the automatic population of virtual landscapes with realistic plants?
Now that the Copenhagen Summit comes close, ETH Zurich has started a Climate Blog with contributions by 20 ETH professors and numerous student and guest authors. Unfortunately, the blog is in German but due to the high impact of climate change for our future landscapes and with regard to our work on climate change visualization at CALP, I inlcuded the ETH climate blog in the LVIZ blogroll. Please follow the blogroll on the right or go directly to http://blogs.ethz.ch/klimablog/.
