IJGI Journal Special Issue: “Human-Centered Geovisual Analytics and Visuospatial Display Design”

A few of us are involved in organizing a journal special issue, loosely linked to the three events (see the previous post) this year. If you work on geovisual analytics/geovisualization and modern cartographic considerations for visual analytics/geovis (from a “display design” perspective), this may be for you. Note that this is an open access publication, this means there’s an article processing charge of CHF1000. This is nothing to do with the guest editorial team, it’s completely managed by the journal. However, the journal was willing to hear waiver/discount requests, so if you do not have the funds from your department/library/funding agency, and you still want to play, we still encourage you to consider.

Everything you need to know is here:


Also important to note that:

  • An expression of interest with a 200-word abstract should be sent to the editorial team latest by 15th of August 2018 at the email address human.isprs.ijgi@gmail.com. Please also mention if you will need a discount or waiver on the open access fees. If your institution has funds for open access publications, please consider that others might not, before asking for the waiver or discount.
  • Deadline for full paper submissions: 15 November 2018

PhD project: Using 3D geovisualisations for urban design: The case of informal settlement upgrading in South Africa

We are starting a new thread in our blog! We will be featuring interesting scientific work done by our members or in our extended community once in a while. We begin by a recently completed PhD thesis, by our working group secretary Dr. Victoria Rautenbach. Victoria (relatively recently, and very successfully) completed her PhD at the University of Pretoria, South Africa. In this post, we provide a summary of Victoria’s PhD project, and link to some of the related publications for those who wish to dig deeper.

ps. On a side note, here’s a lovely moment of cultural fusion in Victoria’s graduation ceremony: https://www.youtube.com/watch?v=zsruVtBrf0s&feature=youtu.be&t=2145


Using 3D geovisualisations for urban design: The case of informal settlement upgrading in South Africa

Informal settlements are a common occurrence in South African due to housing backlogs and shortage of housing subsidies, and are often located on disputed land. To improve in-situ circumstances of these communities, informal settlement upgrades and urban design is required. Spatial data and maps are essential throughout the entire upgrading and urban design process in order to understand the current environment, plan new developments and communicate planned developments. All stakeholders need to understand maps to ensure active participation in the urban design process. Many researchers proclaimed that because 3D visualisations resemble the real environment more than traditional maps, and are more intuitive, therefore 3D geovisualisations are easier to interpret. The question arises whether 3D geovisualisations can support and even benefit the urban design process, in the context of this thesis, specifically for upgrading of South African informal settlements.

To investigate the use of 3D geovisualisation, the following topics needs to be investigated: modelling processes (manual and procedural); visual design (visual characteristics, visual complexity and visual variables); and cognition related to spatial tasks on 3D geovisualisations and comparable alternatives (i.e. topographic maps, aerial photographs, 2D maps) when performing basic map reading tasks. They found that procedural modelling was found to be a feasible alternative to time-consuming manual modelling and has the capabilities to produce high-quality models. The results of four user studies and expert interviews 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 aerial photographs, 2D maps and 3D models. The research results could assist planners in designing suitable 3D models for use throughout the entire urban design process.

Session title: 3D Virtual and Augmented Realities for Geoinformation Science

Recent developments in 3D virtual and augmented reality technologies have spurred industry, research, and education developments that will effect (geo) spatial information science intimately. The ease of accessing 3D information through environmental sensors (Photogrammetry, LiDAR, or 360 degree cameras) and modeling efforts using, for example, ESRI CityEngine or Google SketchUp, allow for creating efficient workflows from environments to digital, interactive 3D models. In parallel, the virtual and augmented technology industry has made substantial progress to provide products that allow VR and AR to enter both mainstream and research in unprecedented ways. The quality and affordability of products such as Oculus Rift, Samsung GearVR, Zeiss VR One, to name just a few, allow for immersive and augmented experiences that have been unparalleled so far.

The proposed sessions continues the inaugural meeting in San Francisco. The opportunities for (geo) spatial information science research and applications are vast, and it is time to provide a forum for discussing industry, research, and education developments that address, but are not limited to, the following topics:

– Efficient workflows for 3D environmental modeling for built and natural environments,
– 3D modeling software for 3D geoinformation modeling,
– Game engines in geospatial research and education,
– Virtual and mixed realities,
– Augmented reality games (e.g., Pokemon Go),
– Spatial temporal data visualization in VR,
– Immersive Visual Analytics,
– Big data visualization and VR,
– User experiences in Geovirtual Environments,
– Accessories for 3D modeling and VR (e.g., 360 degree cameras),
– Digital Cultural Heritage

Organisers: Alexander Klippel (Geography, The Pennsylvania State University), Danielle Oprean (Architecture/Landscape Architecture, The Pennsylvania State University), Craig McCabe (ESRI), Sven Fuhrmann (Geography and Geoinformation Science, George Mason University), Arzu Çöltekin (Geography, University of Zurich, Switzerland), Robert Stewart (Geographic Information Science and Technology, Oak Ridge National Laboratory), Christopher Petit (Urban Science / City Futures, University of New South Wales, Australia).

New name, new team for our WG

During the last ISPRS meeting in Prague, there was a restructuring of the Commissions and Working Groups. Below you will find a summary of the changes:

Name change: Our commission (Spatial Information Science) is now Commission IV, and our working groups is WG IV/9. We also modified the name of the WG slightly, and now we are called “Geovisualization, Augmented and Virtual Reality“.

Team change: We also have some changes in our team. Our past co-chair Dr. Bo Wu decided to step down from the executive committee but remains an active member. We are thankful for Bo’s executive contributions for the last two terms. For the new term, we warmly welcome Dr. Sidonie Christophe of IGN, who is also a co-chair at the ICA commission on Cognitive Visualization. We are looking forward to collaborating more on cognitive and human centered issues. Furthermore, myself and Dr. Chris Pettit have swapped hats (chair <–> co-chair) and I will chair the group for the next four years, while Chris remains actively involved as a co-chair in our executive team. Victoria also continues for another term in her role in our executive team. We are excited to build a community around the topics of (human-centered) geovisualization, augmented and virtual reality. If you wish to collaborate with us, please become a member, and if you wish to organize activities (workshops, special issues and such) under our WG’s umbrella, please drop as an email and we’ll have a conversation. You will find our ‘terms of reference’ below the image.
