Available online:

A tool for visualizing your complete, consolidated, collected Google Location History.

It works directly in your web browser – no software to download, no packages to install. Everyone deserves to know what data is being collected about them, without having to fiddle with cryptic pieces of software.

location-history-visualizer takes raw Google Takeout output and produces a heatmap of all of your location data over time, overlaid on an interactive map.

Packages used

  • leaflet.js, for rendering the interactive map
  • leaflet.heat, for rendering the heatmap overlay
  • filestream, for dealing with gigantic Google Takeout files
  • oboe.js, for processing said gigantic files
  • browserify, for helping filestream work properly in the browser
