NYC Helicopter Noise Explorer
Mapping one month of helicopter flights and noise complaints across the New York City metro area.
What it does
The app provides interactive analytics, charts, map effects, and demographic context for NYC noise complaints and helicopter activity. Explore the data through neighborhood lookup, calendar-based filtering, noise complaint table, and more.
Under the hood
The color of each track reflects helicopter speed, revealing patterns across more than 600,000 flight paths on the map. This visualization is created interactively in Map Viewer as a web map, then integrated into the app via a map component. Data‑driven styles can also be generated programmatically.
A LayerView enables client-side querying and filtering, delivering instant results once the layer is loaded—no network requests needed. The investigation loupe in the app is powered by client-side queries combined with feature effects.
The charts components are web components for building interactive charts, such as the line chart in this application showing flight segments each day by a specific plane. When users inspect flight pattern on the charts, the corresponding flight path is highlighted in the map.
Use the Feature Table component to show the noise complaints attribute in a tabular format. Feature Table provides advanced column customization, attribute editing, and more.
