Semantic Geographics and Online Mapping Route Choice Self-Selection to Build A Database of Alternate Route Choices

Wednesday, July 23rd, 2008

Even though I made Wednesdays “no-blogging days” so that I can get some rest, the SP Gass at Low Tech Times has an interesting article called There’s No Substitute for Looking At A Real MapOpen Source Geography (dot org, FYI), soon to be moving to its own site, fully endorses this notion of looking at a Real Map.

I am interested in SP Gass’s view on the accuracy of the AAA TripTic.  SP Gass is talking about reference maps and how one’s on paper are much more usable.  Beyond portability of a paper map, paper allows one to come up with their own route.    SP Gass knows what he means when he is choosing a route.  But without expert knowledge or human behavior factored in as a determinant in the route choice algorithm, the computer can never approximate what means, his geographic semantics.  Dr. Martin Raubal at University of California-Santa Barbara teaches a course in Geographic Semantics.

Anyway, flexibility in route choice using online mapping software would greatly improve the service.  As a Geographic Information Scientist, by training, I would suggest to Google that they open their street network dataset to allow a local crowd to suggest alternate routes.  Another option would be to generate a sample of automobiles and collect GPS points along their chosen routes, rather than the predictive routes.

I am still imaging the algorithm and/or data-structure required to enable a sample link on a chosen route be chosen to improve the predictive path.  Especially considering that the data would need to be split into nodes and links.  Not to mention, the process of formatting.  Unless of course, you are generating an cloud-enabled database with a G-Phone Android Program in which these points are collected real-time.

Is this possible?  It seems like it should be considering bluetooth tracking and cell-phone tracking would be a great medium for updating Google Maps.

Also, check out Google’s Newest Feature:  GoogleWalking.  Its still in Beta, but there is a smattering of commentary around the web.

Google Maps Walks the Long Way Around by Google Maps Mania.

And this list of 100 Google Earth Mashups isn’t particularly about GoogleWalking, but it is still useful information for improving the semantic web rich with digitized human knowledge.

Letter of Motivation to University of Zurich - Geographic Information Visualization and Analysis Group

Letter of Motivation

The term geographic relevance is new, but is still a familiar concept. With my Master of Science in the Geographic and Cartographic Science and ten years of work experience, I can offer a wide range of real-world contexts in which mobile computing could be studied. I have worked in the geographies of disease, elections, census gathering, business and local urban planning. I can imagine geographic informational relevant applications for each of these and other more popular activities.

To reiterate my understanding of the funded PhD Research Assistant position at the University of Zurich, Department of Geography, Geographic Information Visualization and Analysis Group, the goal of this project is to:

1. Develop methodologies for evaluating the human response to geographic relevance in mobile contexts, starting with activity theory as the research framework.
2. Development of mobile geographic informational applications using Java and data source Mash-Ups
3. Prepare a dissertation

I am interested in this research project as I seek to specialize in the Geography of ubiquitous computing and the energy, infrastructure, policy and locational requirements. I have been looking for a PhD program in this area as they relate to Educational Technologies in Geography. This funded PhD opportunity would enable full development of my ideas, while in direct synergy with the requirements for this project.

My strength would be in the development of the models for human subjects. I was responsible for handling confidential patient data and accountable for adhering to the University Research Protocol Regarding Experimentation with Human Subjects at the University of Virginia. And I was introduced to Activity Theory in my University of Virginia Graduate-level Theories of Learning course. In regards to application development in java, I have a vested interest in strengthening my programming skills. In my spare time, I tinker with the Internet and my latest project is working with the Android programming environment. Android is an open-source java-based programming language on which the GooglePhone (G-Phone) is compiled.
