Windows Phone 8.1 does not upload / sync camera roll photos to OneDrive

Recently my Lumia 920 with Windows Phone 8.1 stopped uploading photos to OneDrive.
Searching the web i found out, that this happens to all photos taken with "Auto Upload" being turned off!
I had "Auto Upload" turned of to save some high speed volume. Even after turing it on again, the photos i took while i was turned of did not sync to OneDrive automatically.

How-I-fixed-it:
There's a very usefull app called "Camera Roll Sync" in the Windows AppStore which allows to sync the photos manually.
Here's the AppStore URL: http://www.windowsphone.com/en-ca/store/app/camera-roll-sync/5b7e86ad-32f7-47f5-95a0-eda5ef0abb31

How to extract and convert images/photos exif GPS metadata to decimal format with exiftool?

I use the great ExifTool by Phil Harvey to extract GPS metadata from images.
The default output for GPS coordinates is styled liked this:
GPS Latitude                    : 48 deg 50' 47.01" N
GPS Longitude                   : 8 deg 35' 21.83" E

I wanted the GPS data formatted in decimal number style.

How i fixed it:
Run the exiftool with the commandline parameters -n -c %.8f and you get

GPS Latitude                    : 48.8463925
GPS Longitude                   : 8.58939861111111
