Chasing Stars is the one-stop solution for the perfect stargazing spots. This app is built for photographers, astronomy enthusiasts, and just anyone who ponders what is out there beyond us.

Chasing stars provides users with the most up to date recommendations by applying light pollution API, weather API, and Geo API through a carefully researched and tested algorithm.

With the newly added community features, users can also upload their own secret spots, share the photos taken there and even shooting parameters. When browsing through star gazing spots, these posts will pop up as a reference.

• Interactive calendar Enable users to browse and select date.
• Location search Search locations based on location name and selected date.
• Dynamic map Display locations with different markers based on each one's star visibility score, click the marker will popup location's info.
• Star visibility calculation Calculate a location's star visibility by applying light pollution API, weather API, and Geo API through a carefully researched and tested algorithm
• Stargazing Recommendation Choose a date and recommend the best stargazing locations of that day
• Explore Display hot posts
• Stargazing Community Allow users make posts with pictures to rate locations, and make comments to other users' posts.
• Authentication System Allow users to login and manage their contents, have admin users to manage the community and maintain locations.

One to One: Location <- Weather(location_id) Location <- Light_pollution(location_id) // each record of weather and light pollution is distinct since they are in different time

Many to One:
User <- Photo(user_id), Post(user_id), Comment(user_id)

Location <- Photo(location_id), Post(location_id)

Many to Many:
User(location_id) <- UserLocation -> Location(user_id)
