Jupyter Notebook: Combining Twitter Data and OpenRouteService Directions API
In the case of a disaster fast response is important and life saving. Information on blocked streets is crucial, but a the same time this infornations needs to be considered by routing engines in real-time. However, many routing engines use street network data which is at best updated once a week or even less often.…
