fog of war

Convert data from different sources to a fog of war-style map. It generates four layers:

• Points: all points from your sources, rounded to 10m and deduplicated.
• 50m radius circles: draws a circle with 50m radius around all points and dissolves them. Holes with a surface smaller than a circle with 50m radius are removed.
• 500m radius circles: same as the 50m circles.
• Heatmap: non-deduplicated points rendered as a heatmap.

Data

Currently supported:

• Strava (.gpx, .gpx.gz, .fit.gz)
• Google Timeline (location-history.json)

Usage

First, prepare the data:

1. Collect all data and put it in the data directory.
2. Install tippecanoe (e.g. brew install tippecanoe).
3. Clone the repo.
4. Run cargo run -r.

Second, render the data. Inside the ui directory, do:

1. bun install
2. bun run dev

You should now be able to see an interactive map on http://localhost:5173.
