Some API functions that return lists of TASKS (e.g. user_get_task_list()) accept a filter expression to limit the amount of results returned.

The string is expressed in JSON format, and the fields supported are:

• type: Specifies how location is defined. It accepts the following values
  • 'GPS': The contents of the JSON will hold GPS coordinates (latitude, longitude, and other typical fields returned by a GPS device)
  • 'address': The contents of the JSON will hold a postal address
• If the location type is "GPS":
  • latitude: expressed in degrees [-90, 90]
  • longitude: expressed in degrees [-180, 180]
  • altitude: expressed in meters
  • accuracy: expressed in meters
  • altitude_accuracy: expressed in meters
  • heading: expressed in degrees [0, 360]
  • speed: expressed in meters/s
  • date: local date when the GPS measure was taken in format 'YYYY-MM-DD'
  • time: local time when the GPS measure was taken in format 'hh:mm:ss'
  • utc_offset: offset of the local time with respect to UTC time
• If the location type is "address"
  • address: a string with a full postal address
