1. Location History (JSON)

• location logs with estimated activities
• Takeout provides location logs as JSON or KML format, here is JSON

• locations : (array/object) location point array
• timestampMs : (string) timestamp in msec
• latitudeE7 : (integer) latitude value in integer. latitudeE7 / 10,000,000 = latitude in degree
• longitudeE7 : (integer) longitude value in integer. longitudeE7 / 10,000,000 = longitude in degree
