You can activate Automatically save added features when you are in editing mode. Or you can activate Automatically add points to the map canvas with a certain width and color.

Activating Cursor, you can use a slider to shrink and grow the position cursor on the canvas.

Activating Map centering allows you to decide in which way the canvas will be updated. This includes ‘always’, ‘when leaving’, if your recorded coordinates start to move out of the canvas, or ‘never’, to keep map extent.

Finally, you can activate Log file and define a path and a file where log messages about the GPS tracking are logged.

If you want to set a feature manually, you have to go back to ^Position and click on [Add Point] or [Add track point].

Conectaare la un GPS Bluetooth pentru urmărirea în direct a poziției¶

With QGIS you can connect a Bluetooth GPS for field data collection. To perform this task you need a GPS Bluetooth device and a Bluetooth receiver on your computer.

At first you must let your GPS device be recognized and paired to the computer. Turn on the GPS, go to the Bluetooth icon on your notification area and search for a New Device.

On the right side of the Device selection mask make sure that all devices are selected so your GPS unit will probably appear among those available. In the next step a serial connection service should be available, select it and click on [Configure] button.

Rețineți numărul portului COM atribuit conexiunii GPS, după cum rezultă din proprietățile Bluetooth.

După ce GPS-ul a fost recunoscut, creați asocierea pentru conexiune. De obicei, codul de autorizare este 0000.

Now open GPS information panel and switch to GPS options screen. Select the COM port assigned to the GPS connection and click the [Connect]. After a while a cursor indicating your position should appear.

If QGIS can’t receive GPS data, then you should restart your GPS device, wait 5-10 seconds then try to connect again. Usually this solution work. If you receive again a connection error make sure you don’t have another Bluetooth receiver near you, paired with the same GPS unit.
