The following functions are used to handle the geo-localization information and to control a GPS device:


geoAzimuth	Returns the direction represented by a position in relation to another one.
geoDistance	Returns the distance between the two positions. This distance is expressed in meters by default.
geoGetAddress	Retrieves an address (or a list of addresses) corresponding to the description of a geographical location.
geoRunApp	Starts the native mapping application of the device to display: a specific geographical position, an itinerary between two positions.
geoTrackingDisable	Disables the tracking of user positions for a WINDEV Mobile application.
geoTrackingEnable	Enables the management of location tracking in a WINDEV Mobile application.
geoTrackingProcedure	Defines the WLanguage procedure that will be called when the user position changes.
geoTrackingStatus	Retrieves the status of the system for position tracking.
GPSDetectPosition	Asks to be notified when the device gets close to a given position.
GPSEnd	Indicates the end of use of geo-localization functions.
GPSFollowMovement	Asks to be regularly notified about the current device position.
GPSGetPosition	Retrieves information about the current device position.
GPSInfo	Returns the information about the localization provider used by the application for the geo-localization functions.
GPSInitParameter	Initializes the parameters of WLanguage functions for geo-localization and finds a localization provider.
GPSLastPosition	Retrieves the information about the last known device position.
GPSStatus	Retrieves the activation status of the geo-localization provider or asks to be notified when the status changes.
GPSStopDetection	Stops the detection of position that was started by GPSDetectPosition.

The following advanced types are used to handle the geo-localization information:


Versions 17 and later Address New in version 17 Address Address	The Address type is used to handle the address of a location or the address of a person.
Versions 15 and later geoPosition New in version 15 geoPosition geoPosition	The geoPosition type is used to handle the geographic positions via the geo-localization functions of WLanguage.

Versions 17 and later

Operating mode in iPhone/iPad

During the first startup of a GPS function, the system asks the user for the authorization to perform a geo-localization. If the user refuses, all the GPS functions used in the rest of the application will fail (fatal error).

To re-allow the use of GPS for this application, the system configuration of the application must be modified.

New in version 17

Operating mode in iPhone/iPad

To re-allow the use of GPS for this application, the system configuration of the application must be modified.

Operating mode in iPhone/iPad

To re-allow the use of GPS for this application, the system configuration of the application must be modified.

Android (WINDEV Mobile): Android GPS

[ + ] This example presents the use of the GPS functions of WLanguage in an Android application.
It is used to retrieve at regular interval:
- The latitude
- The longitude
- The altitude
- The speed
- The direction

Sample Mobile components (WINDEV Mobile): Pocket GPS

[ + ] This application is an example for using the Pocket GPS component.
The following data is returned by the component:
- the longitude: angle between a point found on the Greenwich meridian and a given position in relation to the center of the Earth
- the latitude: angle between a point found on the equator and a given position in relation to the center of the Earth
- the vitesse: movement speed in km/h
- the altitude: altitude in relation to the sea level
To operate, this example requires a GPS device that complies with the NMEA standard.

Cross-platform examples (WINDEV Mobile): WM Geo-localization

[ + ] This example explains how to perform proximity searches with geolocalization:
- search around me
- search in a city, at a given address, or close to a specific address.
The results are displayed in a looper and in a map with markers.
