 # Overview

 Upload 360° photos to Google Maps without using Google's app.
 
-The main reason why I created this is because Google Maps isn't a good replacement of the former app. You are only able to upload 360 photos to specific places on the map. With this project, it is possible to upload them at any coordinates.
