In addition to the two earlier presentations (No 1, No 2), today there are two additional presentations (No 3 & 4) by GIScience Heidelberg at AGILE 2016 conference in Helsinki:
Rousell, A., Hahmann, S., Mobasheri, A. (2016): A Two-Tiered Approach to OSM Data collection for Novice Users. 19th AGILE Conference on Geographic Information Science. Helsinki, Finnland.
It explains some results of the CAP4Access project implemented in the MyAccessibility tools for improving and using Accessibility information in OpenStreetMap, in particular for mobility impaired users such as wheelchair riders.
Although OpenStreetMap (OSM) is a widely used crowd generated spatial dataset, it can be difficult for novice users to enter data in a way that conforms to those data already present. It is often the case however that it is these novice users who have a more invested need for relevant data to be present within OSM, such as is the case with users with reduced mobility. In this paper is presented an approach which allows novice users to contribute information which can then be used to enrich the OSM dataset. This is done via a two-tiered approach whereby one user (the Observer) contributes a textual description via an Android app developed as part of a server-client web service. This text is used to create OSM Notes which are then used by experienced OSM users (Editors) to update the information in the OSM. Using such a method means that the collection and entering of information are the responsibility of the people who are more suited for the task – collection for people who know what creates obstacles in the environment, and entering for those people who know how to update the OSM dataset.
Further our former colleague David Jonitz will present his earlier work on Personalizing Walkability:
Jonietz, D. (2016): Personalizing Walkability – A Concept for Pedestrian Needs Profiling Based on Movement Trajectories. 19th AGILE Conference on Geographic Information Science. Helsinki, Finnland.
