There is a suggestion for the product roadmap. It would be useful to track the history of places visited by people who were later diagnosed on the disease and create a heat map. The system will have a "score" of places based on the number of visits by probably contagious people. The application can provide information about "clean" areas and the areas where additional caution is recommended.

History of places visited by all users are kept in the DB.

If you haven't posted positively, we need your location history so that if someone who's reported positive after you, have been in close proximity with you, you can get a notification.
You have the option to log back in and change your status (positive / negative), while your location history is being stored (for 14 days - current working assumption)
If you have tested positive your history is stored, you can always add the most recent location history as a user

one of the challenges of marking an area "clean" is that it risks giving users a false sense of security, which we must avoid. But agree with you completely on the value of a heatmap!

@cankisagun As for the history of places, we could use a framework like OpenDMTP(We could possibly modify a software like openGTS to suit the req). it is primarily meant for vehicular fleet management, but that works as an advantage since it would let people track positive/negative cases. It also allows geo-fencing so people moving in and out of zones can be notified.
@ainsleys - We could use visual stimuli to show that a clean area may not actually be clean. Usually heat-maps have hot and cold zones shown in a spectrum of blue and red, we could use colors that don't give a complete sense of security, like a spectrum of light orange to bright red.

@tuneerguha I feel like the applications that are interacting with our DB needs to implement openGTS as the web portal we are building depends on Google Maps for location data. Am I missing something?

tuneerguha commented 4 years ago

@cankisagun Not really, It has support for OpenStreetMap. It may not be as accurate as google maps, but i guess its good enough.
