Do you want to add geotagging (latitude and longitude coordinates) to your photos?
This is particularly useful if you use DSLR or mirrorless cameras that often lack this feature.
All you need for this is to have location history enabled in google maps. This process will add a location to a photo based on where your phone reported you where when the photo was taken.
Go to your timeline. and download each day you want to use using the cog at the bottom right
Put the photos to tag and the KML activity files in the same folder, and for each run
1exiftool -overwrite_original -geotag act_ity_file.kml .
If you receive a warning like
Warning: No writable tags set from ./2022-05-08 13.33.27.jpg Warning: Time is too far from nearest GPS fix in File:Geotime (ValueConvInv) - ./2022-05-08 13.33.37.jpg
This means that there are no GPS points within the default 30 minutes of the photo. To extend this time you can use the
-api flag like
-api GeoMaxIntSecs=9999 -api GeoMaxExtSecs=9999. See the exiftool documentation.
