Qt Location

The Qt Location API helps you create viable mapping solutions using the data available from some of the popular location services.

The release of this API with Qt 5.5 is a Technology Preview. This implies a soft API freeze for Qt Location.


The Qt Location API enables you to:

  • access and present map data,
  • support touch gesture on a specific area of the map,
  • query for a specific geographical location and route,
  • add additional layers on top, such as polylines and circles,
  • and search for places and related images.

Getting Started

To load the Qt Location module, add the following statement to your .qml files

import QtPositioning 5.5
import QtLocation 5.5

The QtLocation QML module depends on the QtPositioning QML module. Therefore every QML application that imports the QtLocation QML module must always import the QtPositioning module as well.

For C++ projects include the header appropriate for the current use case, for example applications using routes may use

#include <QGeoRoute> 

The .pro file should have the location keyword added

QT += location


The API is split into sub-modules, which provide QML and C++ interfaces for specific purposes. They focus mainly on Map and Place information. The required position data can be retrieved using the QtPositioning module.


The Places submodule is the natural complement to Positioning, providing a source of geographical data about Places of Interest (POI). Besides the source information, the API provides information about the location, size, and other related information about a POI. The Places API can also retrieve images, reviews, and other content related to a place.

Maps and Navigation

The module provides the QML and C++ alternatives for maps and navigation. The C++ alternative provides utility classes to get geocoding (finding a geographic coordinate from a street address) and navigation (including driving and walking directions) information, whereas its QML counterpart provides UI components to render the information.
