Paths Crossover Detection

Check using GPS coordinates and time stamp if 2 persons crossed paths in a given time frame.

Required files/values

1. The json file from google takeouts which contains the location history of each person.
   You can get this from https://takeout.google.com/settings/takeout
2. GPS coordinats of your desired location/zone to plot the paths crossover using basemap.
   You can get this from https://www.openstreetmap.org
   How to get the coordinates is explained in the workbook 'Paths_Crossover_detection.ipynb'

Workflow

1. Use the file 'Location_history_converter-json_to_excel.ipynb' to load the 'Location History' json files of both persons and convert the data into excel files.
   
2. Use the file 'Paths_Crossover_detection.ipynb' to load the excel files from previous step and plot it to detect the paths crossover and to find the exact GPS coordinates with timestamp.
