The Walk is a virtual walking machine harnessing geolocation, weather data, and generative Artificial Intelligence.
What it does?
Starting with a pair of coordinates (lat/lng), it will calculate a point at a distance, it will get directions from Google Maps and it will start a virtual journey getting pictures and weather data for a diary that it will write using ChatGPT.
During the trip, a screen will display all the information and pictures.

Web site to publish current location
You can upload php files to a web server in order to publish The Walk location. Remember to edit the web site URL into thewalk_,,,py settings
CSV files
The Walk use 3 CSV Files.
Coordinates.csv file is used for current location. Just one record with lat-lng.
TheWalkLog.csv is used to store every movement: timestemp, origin, destination, distance. map, snapshot and weather conditions
Row example: 2023-09-04 09:27:22.558367,-34.561641,-58.4819516,-34.564203,-58.48763710000001,592,'/home/roni/images/route-500835d3-b13b-4a17-b7d2-546fcdc605e9-5.jpg','/home/roni/images/snap-500835d3-b13b-4a17-b7d2-546fcdc605e9-5.jpg','clear sky'
TheWalkJournal.csv is used to store the diary.
The later 2 csv will be imported to a database and used in the future to plot The Walk complete journey.
Example of the AI generated diary
“I have finally reached my destination with a feeling of great relief. After my 2705 meter walking journey, I am feeling exhausted but satisfied and content. The clear sky weather was glorious and the sun shone brightly on my journey, yet the air was still cool and refreshing. The sight of Gral. José Gervasio Artigas 469, C1406ABE CABA, Argentina was a beautiful sight and I am so grateful to have made it here in one piece”
