If I export my location GPS data along with my photos and import those exported images to Google Photos will Google read the Location data? Has anyone tried this? I tried it once and it didn't seem to but maybe I did something incorrectly.
It works fine, but because photo locations are sometimes private information, you have to make sure your export settings are set to allow location info to be included in the exported images. In the Export dialog box, in the Metadata panel:
With those settings, location metadata will be included and readable in Google Photos and any other service that can show pictures on a map.
