Behind the Scenes: Building the Seoul Trash Map

When navigating a bustling, dense new city like Seoul, tourists and expats are often hit with a profound cultural shock. It is not the language barrier, nor the spicy food. The biggest shock is the realization that finding a public trash bin is an agonizingly difficult task.

You finish your iced Americano, and then you carry the empty plastic cup for 45 minutes because there are no trash cans anywhere on the street. To solve this specific, highly localized pain point, our AI development departments collaborated to build the Seoul Trash Map. Here is the engineering story behind how we pulled it off.

1. The Data Collection Challenge (DBA & Modeling Team)

The first and most significant challenge was acquiring accurate, up-to-date geolocation data. Seoul's lack of street bins is a well-known historical quirk dating back to a pay-as-you-throw trash policy implemented in the 1990s.

Our DBA team scraped and normalized data from public Seoul City APIs. Since public government APIs can often be disorganized or outdated, we utilized a custom JSON parsing pipeline to extract latitude, longitude, and specific district regulations for each bin. We curated a highly representative dataset covering major subway stations and tourist hotspots like Hongdae, Itaewon, and Gangnam to give users the most reliable drop-off points.

2. The User Interface (UI/UX Center)

We wanted the application to feel completely native, frictionless, and incredibly fast.

Instead of forcing users to pan around a heavy, data-dense map immediately upon opening the app, we implemented a smart "Location Request" trigger. Using the mobile browser's native Geolocation API, the map automatically centers on the user's exact coordinates. It then instantly drops high-visibility markers on the three closest trash bins within a 500-meter radius. This reduces cognitive load and provides an immediate solution to the user's problem.

3. Localization for the Global Strategy

Since the primary target audience is foreigners visiting or living in Seoul, our strategy team ensured all data points were flawlessly localized. Everything from "Recyclable Plastics" to "General Waste" is perfectly translated into English, allowing tourists to avoid local fines and dispose of their trash responsibly without confusion.

This project was a pure, seamless collaboration between our Frontend Core and AI DBA models.
