I would like to use a dataset of GPS coordinates (with time if available) of people (preferable tourists) visiting places in a city.
I would like to use it to compute a map layer with the intensities or frequencies of visits.
I have been using an application to make journeys by my city to make some tests but I would need much more data to accomplish the project.
Where or how can I find it? City place or transportation used by people in that city is not a need (although is preferable walking people).
