Qt Location

The Qt Location module helps you create mapping solutions using data available from popular location service providers, such as Open Street Map.

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.
  • Search for places and related images.

Using the Module


To use the types, add the following import statements to your .qml file:

import QtPositioning
import QtLocation

Note: Many Qt Location QML module APIs are using types from the Qt Positioning module. For example, defining a coordinate to be the center of the map requires types from the Qt Positioning module.


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

#include <QGeoRoute>

Using a Qt module's C++ API requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.

Building with CMake

Use the find_package() command to locate the needed module component in the Qt6 package:

find_package(Qt6 REQUIRED COMPONENTS Location)
target_link_libraries(mytarget PRIVATE Qt6::Location)

For more details, see the Build with CMake overview.

Building with qmake

To configure the module for building with qmake, add the module as a value of the QT variable in the project's .pro file:

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.
