Python script to reproduce the Strava Global Heatmap (www.strava.com/heatmap) with local GPX data
Optimized for cycling activities 🚴
Check out github.com/remisalmon/Strava-local-heatmap-browser for an interactive version
- Minimal Python dependencies (matplotlib+numpy)
- Fast (3x faster than
gpxpy.parse())
- Download your GPX files from Strava and add them to the
gpxfolder
(see https://support.strava.com/hc/en-us/articles/216918437-Exporting-your-Data-and-Bulk-Export) - Run
python3 strava_local_heatmap.py - The heatmap is saved to
heatmap.png
usage: strava_local_heatmap.py [-h] [--gpx-dir DIR] [--gpx-year YEAR]
[--gpx-filter GLOB]
[--gpx-bound BOUND BOUND BOUND BOUND]
[--output FILE] [--zoom ZOOM] [--sigma SIGMA]
[--no-cdist] [--csv]
optional arguments:
-h, --help show this help message and exit
--gpx-dir DIR GPX files directory (default: gpx)
--gpx-year YEAR GPX files year filter (default: all)
--gpx-filter GLOB GPX files glob filter (default: *.gpx)
--gpx-bound BOUND BOUND BOUND BOUND
heatmap bounding box coordinates as lat_min, lat_max,
lon_min, lon_max (default: -90 +90 -180 +180)
--output FILE heatmap name (default: heatmap.png)
--zoom ZOOM heatmap zoom level 0-19 (default: 10)
--sigma SIGMA heatmap Gaussian kernel sigma in pixels (default: 1)
--no-cdist disable cumulative distribution of trackpoints
(uniform distribution)
--csv also save the heatmap data to a CSV file
--zoom is OpenStreetMap's zoom level, first number after map= in www.openstreetmap.org/#map=
Example:
strava_local_heatmap.py --gpx-dir ~/GPX --gpx-year 2018 --gpx-filter *Ride*.gpx --zoom 13
