# Qt Positioning QML Types

#### Overview

The identifying string for this module is QtPositioning. To use include the following import statement in the QML file.

    import QtPositioning 5.2

##### Positioning QML Concepts

Position information can come from a variety of sources including satellites, wifi, text files and so on. The position is described by the latitude, the longitude, and the altitude in meters. For more information see Geographic Coordinate.

The QML position is stored in a coordinate which contains the latitude, longitude and altitude of the device. The Location contains this coordinate and adds an address, it also has a bounding box which defines the recommended viewing region when displaying the location.

Now that the device has a position, with regular updates the API can determine the speed and heading of the device. It can also define a box or a circle that can produce a notification when the device either leaves or enters that region.

More detailed information retrieving the current position can be found under Location Positioning via QML

#### Basic Types

coordinate | Type represents and stores a geographic position
geocircle | Type represents a circular geographic area
georectangle | Type represents a rectangular geographic area
geoshape | A geoshape type represents an abstract geographic area

#### Alphabetical Listing of All QML Types

Address | QML type represents a specific location as a street address
CoordinateAnimation | A PropertyAnimation for geo coordinate properties
Location | Type holds location data
Position | Type holds positional data at a particular point in time, such as coordinate (longitude, latitude, altitude) and speed
PositionSource | Type provides the device's current position
QtPositioning | Global object provides useful functions for working with location-based types in QML
coordinate | Type represents and stores a geographic position
geocircle | Type represents a circular geographic area
georectangle | Type represents a rectangular geographic area
geoshape | A geoshape type represents an abstract geographic area
