Rust reimplementation of derive. Takes a Strava data export and renders heatmaps based on activities.

Example usage

Static Heatmap

The command

cargo run --release -- \
    --lat=46.25 --lon=6.1 --zoom=11 \
    --width=600 --height=400 \
    --tint=0.6 \
    --heatmap=squadratinho \
    --output=heatmap.jpg \
    ~/Downloads/strava

gives me this heatmap:

Animated Heatmap

Using the --stream argument and --frame-rate to control after how many tile updates new frames are produced

cargo run --release -- \
    --lat=46.25 --lon=6.3 --zoom=9 \
    --width=600 --height=400 \
    --tint 0.7 \
    --heatmap=squadrat \
    --stream --frame-rate 1250 \
    ~/Downloads/strava \
    | ffmpeg -i - -y heatmap.gif

and produces an animation:
