A Monitoring Tool for OpenStreetMap Mapathons in Python
In the last couple of weeks disastermappers Heidelberg and GIScience members were interested in finding a way to monitor changes in the OpenStreetMap database. This could help to provide better feedback after mapathons and could allow to measure how many objects like buildings or roads were created or modified during a mapathon. (It was even…

Deriving incline values for street networks from voluntarily collected GPS traces
When producing optimal routes through an environment, considering the incline of surfaces can be of great benefit in a number of use cases. For instance, incline may be considered when computing the most energy-efficient routes for electric cars and bicycles. Likewise, pedestrians with restricted mobility (such as wheelchair users, parents with pushchairs, and the elderly)…
