GeoTag is a free macOS application that allows you to update image metadata with geolocation tags by panning and zooming in a map window and then clicking on the location where a photo was taken. It is a good way to add location information to photos or fine tune existing location information.

Image file updates are performed using Phil Harvey’s ExifTool. This allows geolocation data to be modified an unlimited number of times with no image degradation as ExifTool modifies metadata without changing the image data. See https://exiftool.org for information regarding ExifTool.

Bug fixes in version 4.13

I screwed up 4.12, breaking window resize and the map search bar. 4.13 is 4.12 plus fixes for the things I broke. Sorry.

• The map search bar got buried under the map and somehow I didn’t notice before releasing 4.12.

• Resizing window did bad things

New Features in version 4.12

• Add the ability to adjust the Time Zone used by the code that matches image timestamps to track log timestamps when assinging locations from a track log. Edit -> Adjust Time Zone is the new menu item to initiate selection of a Time Zone. It is only necessary to adjust time zones when the Camera date/time does not match the date/time of the computer running GeoTag.

• Change display color of changed but not yet saved fields to green. This helps identify work in progress when changing the location or timestamp of several images.

• ExifTool 12.30

Bug Fixes in version 4.12

• Remove broken help page. Instead link to the help information on www.snafu.org.

Known Bugs

• Race condition: When photos with the same name are among multiple images opened one may fail to open. An alert is displayed when this happens.
• Setting the date of an image outside of the range of 1970-2034 may result in an incorrect GPS Date Stamp. This is a limitation of how GeoTag, ExifTool, and macOS libraries handle date and time. One hopes that the year 2034 limit will eventually be removed ;)

Notes:

• Photos (OSX 10.10.3 and later) will let you modify existing location metadata but not add location data to an image. If necessary use GeoTag to add location metadata before importing the images into Photos. This may also hold true for other image editing applications.
