Post-Workshop Feedback

Page history last edited by Peggy Agouris 10 years, 11 months ago

Dear colleagues,


To contribute towards providing NSF (and other interested agencies and sponsors) with the most up-to-date view of the scientific field of geospatial and geotemporal informatics, please use the comments space of this page to provide your views in response to the following questions:


1. What do you think is missing from the preliminary list of workshop findings? Please refer to the relevant page for a complete list of the topics that were identified during the workshop.

2. In your experience, what is the single, most important relevant development that occurred since the completion of the workshop, and why? Please include any developments that had an impact on our community's current and future research agenda or that are expected to revolutionize the field in the future.

3. How would you summarize the top new research directions that you have already seen emerging in the field of geospatial and geotemporal informatics?

4. In your opinion, which of the topics that you identified above deserves the immediate attention of the research community and the potential support of sponsors?


Please provide your opinions as comments attached to this page. Bullet-style, concise responses are preferred. All comments will be included in an updated report which will be submitted to NSF. We would appreciate receiving your comments by November 30, 2010.


Thank you in advance for your cooperation and your feedback!

1. I think there should be an explicit mention of Volunteered Geographic Information (VGI), which took hold after the Dec 1997 workshop at UCSB and has since established itself has a major initiative in GIScience.

2. It is hard to measure developments as single time events, but I would suggest that integration of Web 2.0 technologies for spatial applications is the most important development in the past two years.

3. For this question, I am going to take a more narrow perspective and argue that given the increase in multi-modal portable devices, the usability of GPS-based navigation systems and their impact (both positive and negative) on spatial acquisition. This area also ties into the area of geographic visualization, which continues to expand.

4. As new tools are developed, there needs to be an increase in usability studies to ensure that the new geospatial tools are meeting the needs of users.

Hi Peggy and Stephen,

Great thoughts. I also think that VGI and many open source data offers great opportunities for spatial-social nowcasting for population dynamics and gespatial events. Nowcasting is a term used in meterology for weather forecasts in the next 6 hours or shorter. The same ideas can be applied for spatial-social dynamics with VGI and open source data (like google trends, etc.).

Another topic of great interest to me is what I called geospatial narratives. Narratives are ways that we make sense of things and happenings in space and time. I think that geospatial narratives provide powerful integration of space and time.

I second the crowdsourced idea. To what extent might it replace centralized official data collection? What limits might it impose on the prices and restrictions that the official data collection agencies would prefer to have? Might they retaliate with a legal, rather than a technical, strategy?

autononomous navigation as an application of GIS

The "secret sauce" of Google's autonomous navigation advance over the DARPA Grand Challenge is the use of Google's street database, which is accurate to the individual lanes. See Sebastian Thrun's keynote talks at ACM SIGSPATIAL GIS in Nov and at the Nvidia technical conference in Sept. The latter is here: http://www.nvidia.com/object/gtc2010-presentation-archive.html . I.e., by using cars and highways more efficiently, this application of GIS may have a macro effect on the energy crisis. GIS contributes to national productivity.

1. Participatory sensing and geo-social applications.
2. The merging of location-based-services with social-networks
3. I think the next generation computers are tasked to blend the real-world with the virtual-world. We are already witnessing this through the excitements over location-based-services, social-networks, participatory-sensing (crowd sourcing) and online map-mashups. At IMSC (see http://imsc.usc.edu/, we call this new geo-socio-temporal computing paradigm: “Geo-Immersion”. This is when information-access will become a supporting tool for people’s playing, working, learning, etc.
This paradigm uses the four dimensions of “what, when, where and who” to enable people naturally operate in this hybrid virtual-real world. After all, human brain is wired to operate in time and space.
I would like to clarify here that my vision, Geo-Immersion, and the way I would prefer to interpret the concept of “blending the real and virtual worlds”, is much broader than the previous topics of augmented-reality, virtual-reality and such. The reason is that the focuses of these older topics were mainly on the computer-graphics and visualization aspects of the Geo-Immersion. However, to me, the more exciting topics are now in the fusion of human behaviors in these two worlds. And that is why I think Geo-Immersion is more than a research topic and hence its categorization as a new computing paradigm. In my classes, when I ask my students what is their prominent use of computers, two answers are dominant: social-networking and mobile-apps (e.g., on cell-phones or iPad). To me, social-networking is bringing the real-world and its social fabric to the virtual world. And mobile-apps bring the virtual-world and its efficiency and flexibility to the real world. That is the fusion I am talking about, not the visual integration of bits and atoms!
4. The integration of social networks with geospatial and temporal spaces.
