Start watching position

geo.start()

This will remove all previous positions

To use after geo.stop() to continue watching without initializing the data

Get all positions

var positions = geo.data

Get latest position

var position = geo.latestPosition

Position object

The positions are objects with the following keys:

• lat (latitude)
• lng (longitude)
• alt (altitude)
• timestamp (milliseconds since 1 January 1970 00:00:00 UTC)

Events

Listen to the following events

• 'start'
• 'stop'
• 'restart'
• 'position' (callback argument is the new position)

with

geo.on(<event-name>, function() {  })

For example

geo.on('position', function(pos) {
    console.log(pos)
    // logs latest postion
})

Convert to GPX

There is a separate library to convert geo.data to GPX: geolocation-to-gpx
