Neo-Geography And Geography Education In The Japanese Universities, Yuichiro Nishimura
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
The author would like to discuss the state of the geographic education and the neo-geographical practices in Japan. Most of the geography education in universities are still old-fashioned and aimed for educating professionals, the new type of mapping practices like neo-geography are dissociated from it (Dodge and Perkins, 2008) In recent years, such neo-geographical practices also became popular in Japanese society. People come to recognize the importance of geospatial data especially when they facing at the several heavy disaster situations in Japan. For example, Japanese registered users of OpenStreetMap are over 3,700 in September 2013 (http://wiki.openstreetmap.org/wiki/User:Techstrom/JapanData) and the users still …

Introduction To A New Geo-Referenced Street Level Content: 3d Geopano, Boram Yoon, Impyeong Lee
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
Geospatial mash-up is to produce a new worthy value by combining geo-referenced contents and different kinds of service. Despite of its high popularity in aerial view contents such as Google Earth, it is hardly achieved especially in street level due to the poor georeferencing quality of the underlining street level contents. In this study we propose a new street-level georeferenced panorama image content, ‘3D GeoPano’. While the most existing contents provide only the location and orientation for each entire image not for each pixel, this new content is accurately georeferenced pixel by pixel so that one can derive 3D absolute …

Distributed Agents For Contextual Online Searches, Elizabeth-Kate Gulland, Simon Moncrieff, Geoff West
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
As semantic web use and research blossoms, automated online searches - whether to answer a simple question, seek specific sensor readings, or investigate research in a particular domain - has raised a number of issues. Simple search tools cannot handle context-specific search problems, but specialist search tools have a narrow domain and applicability. Some online tools circumvent these problems by putting more filter controls into the hands of users, but this leads to more complex interfaces which can raise usability barriers. A distributed approach, where specialised search agents act autonomously to find contextualised information, can provide a useful compromise between …

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
In developing countries most of the urban dwellers don’t have access to sewer system. People are mostly using “onsite” systems such as septic tanks or pit latrines that need to be emptied periodically, as the densely built urban environment won’t allow new pits to be dug every time they fill up. In the conventional fecal sludge collection systems, authorities are collecting the sludge from house to house and dump on the plant. Fecal sludge collection system is different from traditional vehicle routing and even from solid waste collection system in terms of dynamic collection points, urgency of getting the service …
House Number Interpolation For Route Planning Applications, Stefan Funke, Sabine Storandt
House Number Interpolation For Route Planning Applications, Stefan Funke, Sabine Storandt
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
Nowadays users expect door-to-door routing from a navigation system; for a given address including street name and house number this requires at least an approximate location on the routable part of the OSM data. Of course, eventually the goal is to have every single building mapped and tagged in OSM with its housenumber. For most regions this is still a pipe dream, though. Often, only a small subset of the buildings have been mapped, and even if mapped, quite frequently their housenumber is missing. In particular buildings mapped automatically from aerial imagery typically lack more detailed tags. And even though …
