FAQPage Schema
How do I generate a heatmap from Strava activity polylines?▼

Strava polylines are encoded text strings representing route coordinates. This skill decodes summary_polyline data from your local Strava database to extract latitude and longitude points for rendering training routes on a map.

Can I visualize my Strava training routes on a map without an internet connection?▼

Yes, you can visualize routes offline. This skill reads the local Strava database, decodes the activity polylines, and renders a standalone HTML file so you can review your training locations without needing a live connection.

What is the best way to review where I have trained using Strava data?▼

The best way to review training locations is to generate a visual heatmap. This skill decodes polylines from your local Strava database and renders a Leaflet map, providing a quick visual summary of your workout areas.

Does this heatmap tool require a live connection to the Strava API?▼

No, a live Strava API connection is not required. This skill operates by reading and decoding summary_polyline data directly from your existing local Strava database to generate the heatmap.

What format is the Strava heatmap output saved in?▼

The heatmap output is saved as a standalone HTML file. This self-contained file uses Leaflet to render the decoded coordinates, making it easy to open and share your training route visualization.
