Mapping a city's anti-space to pedestrians

Post date: 2021-10-16 12:46:41

Through the pandemic I have been recording GPS tracks of exercise walks, now adding up to 272 tracks and 2895 km. I am curious what I can do with them in GIS or data processing software. It's easy enough to roughly overlap them all in Google Earth Pro, but I would like to see a heat map of the probability of any particular area being visited. It also occurred to me that it would be neat to see a representation of the inverse of the pedestrian-walked area: the places which are obstructed to a person on foot.

I'd love some help getting started. Is there already freeware software available to do this, or am I looking at data manipulation using my own code? What software should I be looking at?

I can export the GPS tracks individually or as a set, in GPX, KML, and GeoJSON formats — which are presently meaningless to me beyond knowing that KML will open in Google Earth Pro.
