A heatmap is perhaps the most visually striking way to see the scale of your adventures. Instead of hundreds of individual lines on a map, you see a single «glowing» trail of your progress for each year of riding.

Usually, these features are hidden deep behind expensive subscriptions in cloud services, but in BikeNote, I took a different approach.

What is a Heatmap?

It’s a visualization of all your GPX tracks at once for a specific year. The places where you’ve ridden most often glow brighter, while rare routes remain thin, delicate threads. This allows you to instantly see:

• Which neighborhoods or regions you have explored inside and out.
• Where the «white spots» on the map are — the places you haven’t visited yet.
• Your real geographic coverage for every year of your cycling journey.

Why Local Generation is Great

In most services, building a map requires sending your data to a server, waiting for it to process, and then receiving a static image. In BikeNote, everything happens directly in your browser:

1. Speed: modern browser performance is powerful enough to instantly render thousands of data points.
2. Privacy: you build a map of your secret routes and home-to-work locations without sharing coordinates with third parties. Your private geography remains yours alone.
3. Autonomy: you don’t need an internet connection to refresh your memory of last summer’s routes.

How it Works in BikeNote

You don’t need to be a cartographer. The process is as simple as it gets: you just upload your GPX files into the app, and within seconds, your personal heatmap is ready. You can change the scale, study the details, or simply admire the overall pattern of your roads.

Why is it part of the Pro version?

Creating a yearly heatmap requires complex mathematical data processing and efficient browser memory management. I moved this functionality into BikeNote Pro so that users who value deep visualization and the aesthetics of their achievements can get the most out of their data.

It’s not just a picture — it’s the story of your roads, gathered into one beautiful and clear report.
