Visualize Location History

Libraries and some tools for creating engaging visualization from location history data.

Most easily extracted from Google Takeout.

Examples

The implemented visualizations help showing how your year went in relation to a anchor location, think home/work. This lets you easily identify days where you stayed home, worked or were on a trip!

In this example, we see a week long trip in the middle of the year and a 3 month trip towards the end of the year.

Instructions

1. Visit https://takeout.google.com/ and request downloading location history data.

2. Wait for data to be ready.

3. Download data, then run script directly on the archive downloaded, for example

   go run .\cmd/takeout_to_chart/main.go --input=.\takeout.zip --anchors=2014-01-01,10.0,10.0:2016-02-01,20.0,20.0

Use as library

The parser is a non-trivial piece of code. Consider using it as library in your own project:

import "github.com/panmari/locationhistory/internal/reader"

// ...
r, err := reader.OpenFile(*input)
if err != nil {
    log.Fatalf("Error when reading %s: %v", *input, err)
}
decoded, err := reader.DecodeJson(r)
if err != nil {
    log.Fatalf("Error when decoding %s: %v", *input, err)
}
// do something interesting with `decoded`
