Key Facts
- ✓ A developer created an interactive web application to map the locations of active US lighthouses and navigational aids.
- ✓ The project was inspired by the difficulty of finding a single, comprehensive source for this information during a personal research session.
- ✓ The application uses the U.S. Coast Guard's annual light list as its primary data source, ensuring accuracy and completeness.
- ✓ A key feature of the map is an animated visualization that illustrates the unique light characteristics of each beacon.
- ✓ The tool was developed with assistance from Claude Code to extract and process geographic coordinates from the official data.
- ✓ The creator emphasizes that the map is for informational purposes only and should not be used for actual navigation.
A Beacon of Data
A new interactive web application is shedding light on the intricate network of navigational aids that guide mariners along the United States coastline. This digital map provides a comprehensive visual guide to active lighthouses and beacons, transforming a traditionally static government document into an engaging educational tool.
The project was born from a weekend of curiosity and a desire to make complex maritime data more accessible. By combining publicly available information with modern visualization techniques, the application offers a fresh perspective on these historic and functional structures.
From Flu to Function
The journey to creating this map began with a simple Wikipedia exploration. While recovering from the flu, the developer embarked on a deep dive into active American lighthouses. This research quickly revealed a significant gap in available resources: finding a single, comprehensive source or interactive map that detailed these beacons and explained their technical characteristics proved surprisingly difficult.
This challenge sparked the idea for a solution. The developer identified a key resource maintained by the U.S. Coast Guard, which publishes an annual list of active lights. This authoritative document contains the precise data needed, but it exists as a dense publication rather than a visual tool. The project aimed to bridge this gap, turning raw data into a user-friendly experience.

Building the Map
With a clear goal and a data source in hand, the development process moved forward. The U.S. Coast Guard's annual light list, published by the Navigation Center, served as the foundational dataset. This publication includes the location, color, characteristic, and any relevant remarks for each active navigational aid.
To bring this data to life, the developer utilized Claude Code to assist in extracting the latitude and longitude coordinates from the list. This automated assistance streamlined the process of compiling the data needed for a web-based application. The result is a small, focused webapp that not only maps the physical locations of these stations but also provides an animated visualization to illustrate their unique characteristics.
- Location data for each lighthouse and beacon
- Color specifications for visual identification
- Characteristic details explained through animation
- Official remarks from the Coast Guard
Visualizing Characteristics
One of the most innovative aspects of the application is its animated visualization of lighthouse characteristics. A lighthouse's characteristic refers to its unique light pattern—such as a fixed beam, a flashing light, or a specific sequence of flashes. These patterns are a critical form of identification for mariners at sea.
By animating these patterns, the map provides an intuitive way to understand what makes each beacon distinct. This feature transforms abstract technical descriptions into a clear visual representation, making the information more digestible for enthusiasts and the general public alike. The application serves as an educational bridge, connecting users to the complex language of maritime navigation.

Context and Inspiration
The developer's personal connection to the subject matter adds a layer of depth to the project. Having lived in coastal cities like Seattle and San Francisco, there was a pre-existing appreciation for the maritime infrastructure that defines these regions. This familiarity likely fueled the interest in creating a tool that could make the world of lighthouses more accessible to others.
The project highlights a broader trend of using technology to democratize access to specialized information. By leveraging open data and modern web development tools, it's possible to create powerful resources that serve niche communities and curious minds. This map stands as a testament to how a simple idea, sparked by personal interest, can evolve into a valuable public resource.
A New Perspective
This interactive map represents more than just a collection of data points; it is a celebration of maritime history and navigational science. By making the U.S. Coast Guard's annual light list visually engaging, the application invites a wider audience to explore the fascinating world of lighthouses and their role in modern navigation.
While the tool is intended for informational and educational purposes only, it underscores the potential for creative data visualization to bring static information to life. It serves as a compelling example of how personal projects can fill informational voids and provide new ways to appreciate our world's navigational heritage.
