Inspiration

Sometimes wanting to do the right thing can be inconvenient if you have to carry around some recyclables after you're finished with them

What it does

At literally the touch of a button, our app allows city-goers to find and get directions to the nearest recycling bins in the NYC OpenData database

How we built it

We used NYC's OpenData database to make queries to locate all of the available recycling bins in New York City and sorted them based on distance from the user's current location. Then using Google Maps API and MapKit we were able to pinpoint and display locations of the nearest recycling bins.

Challenges we ran into

Asynchronously requesting data from the OpenData API
Adhering to the MVC architecture on the iOS App
Instantiating ViewControllers with efficient transfer of data
Handling unexpected nil cases
Unchartered libraries

Accomplishments that we're proud of

We added small UX experiences that we didn't initially plan out
We finished our original MVP
Sorting the locations by distance ourselves

What we learned

Asynchronous HTTP request and JSON parsing in Android (Java) is a pain
The Earth's longitudinal distance affects the calculation of the distance between two geographical coordinates
