A word of warning if you have bought or are about to buy a GoPro Fusion and need to rely on GPS coordinates. I've upgraded to this camera from a Nikon Key Mission 360 because of the Fusion's integrated GPS... and I've been badly let down.
The GoPro Fusion has two cameras writing image pairs to their own memory cards. The GPS information is only stored in the front camera image (which is fine) in an EXIF header... a block of metadata which includes lots of useful things about when/where/how the photo was taken. The GPS coordinates are expressed in degrees, minutes and seconds... the latter being a decimal value so lots of decimal places to support the full accuracy of GPS. All good so far.
GoPro Fusion Studio is the desktop software which fuses the front/back fish-eye photo pairs together and can create my desired equirectangular projection panoramic image. Apart from EXIF data which is specific to the camera, the output images should have the same data... passed through without corruption... time taken, coordinates, etc. Someone has reported that the date taken data is damaged, but my problem is that the GPS coordinate data is corrupted. The decimal part of the coordinate seconds component has been rounded/integerised. Those precious decimal points are the difference between a GPS-accuracy location and being several tens of metres out and not practical to overlay on a street map.
The response I got back from Support today was disappointing. They seem to be treating it as a feature request and not a bug. They also claim that it's "nothing that we currently have the ability to change", which sounds like nonsense to me.
Come on GoPro. As an experience software engineer, I know that selectively copying through EXIF information is really easy compared with the image reprojection functions. Fix the EXIF bugs soon please!

I've got a iMac because of your information want to keep the GPS data after stitch front and rear footage but the result seems same as Windows.
