The PicaGeotag software allows you to Geotag images taken by a camera with GPS tracks recorded by a phone.
For the images to be perfectly positioned it is essential that the time difference between the camera and the phone is perfectly known.
This application allows you to automate this calibration operation. To do this, simply take a photo of the screen with your camera.
The PicaGeotag software, by analyzing the photographed barcode, will precisely determine the time shift to apply so that the images are perfectly positioned.
