As part of the MyAccessible.EU project (CAP4Access funded by the European Commission), GIScience at the University of Heidelberg has produced a number of tools aiming at improving accessibility for people with reduced mobility and raising awareness to the challenges faced by those people with regards to getting around everyday environments.

On this page you can find links to the various tools developed and collaborated with at GIScience for the project. Many of these tools are still under development, and so any bugs that you find whilst using them or suggestions for improvements please send to

The Obstacle Tracker Mobile App forms the main data collection component of the Obstacle Tagging Service. Running on Android devices it allows people to mark obstacles in their environment and provide a textual description, a photograph, and mark whether it is temporary in nature. Once recorded, the obstacles can be uploaded at a time of choosing and are then available for others to view either via the Obstacle Tracker Web Map or within the Mobile App itself.
The web map component of the Obstacle Tagging Service is the primary location for people to view the obstacles recorded by others. Not only can they view the obstacles and corresponding description and imagery, they can also view local Mapillary imagery alongside the obstacles in the area.
The well established OpenRouteService has been extended to allow for routing where important properties for people with reduced mobility are taken into account. These properties include avoiding steps, the specification of maximum values for slope and curb height, and the selection of preferred surface material to traverse.
The Wheelchair Navigation App is an Android navigation tool that makes use of the wheelchair routing provided by the OpenRouteService to navigation a person from their current location to a desired destination. This destination can be selected from Wheelmap locations, local public toilets, or can simply be searched for within the app. Not only does it provide routes that aim to be suitable for wheelchair users based on preferences entered by the user, it also delivers instructions in a format that is easier for pedestrians to understand by making use of local landmarks within the instructions.
