GeoTag for macOS -- macOS 14 or later

GeoTag is a free OS X single window application that allows you to update image metadata with geolocation tags by selecting one or more images then panning and zooming within a a map to the place the image was recorded. Clicking on the map will add the location to the selected photos. Clicking on a new location will change the geolocation for the selected photos. Zoom in on the map and fine tune the location with a click. The built in ExifTool utility is used to write location data to the images when you save your changes. ExifTool only modifies image metadata -- your image pixels are not touched.

See http://exiftool.org for information about ExifTool. ExifTool is built in to GeoTag.

GeoTag 5.2+ requires macOS Sonoma or later. Use GeoTag 5.1 if running on macOS Ventura. Those running earlier versions of macOS can use GeoTag version 4.15.

GeoTag 5.3

Updates

  • Images can be selected from your Photos Library. Timestamps and locations can be changed and "written" back to the library. The original file is not modified. No backups are made.
  • Map pins can not be dragged. Click on the desired location to move a pin.
  • Copied/Cut coordinates are now in the same format as selected in GeoTag settings.
  • Map configuration options are now in a map context (right click) menu.
  • At an appropriate zoom level you are given the option to use a 3D map representation. Look for the "3D" button near the upper right corner of the map.
  • The last 10 map searches are saved across GeoTag runs.
  • Updated app icon to match current guidelines re size and rounded corners
  • You can "fuzzy" search for images in the table by name.
  • Copy and paste format changed: the coordinate separator is now ", ". A separator of "| " is also accepted for backward compatibility. Example (lat, lon, elevation): 38.530196, -123.214981, 466.38 Elevation is optional.
  • Bug Fix: cancelling a search no longer looks up whatever happended to be typed into the search bar.
  • Bug Fix: Changing the map style no longer repositions the map.
  • Bug Fix: Coordinate format changes take effect immediately in the image table.
  • Bug Fix: Data in XMP sidecar files was not read unless the XMP file was in a folder that was opened or the XMP file itself was explicity opened. Note: xmp files can no longer be selected to open.
  • Bug Fix: Duplicate image processing does more than give a warning.
  • Bug Fix: extraneous map centering removed
  • Bug Fix: Time zone handling when adjusting for zones with a non-zero number of minutes east of GMT.

Issues

  • undo/redo menu items are always enabled, even when there are no undo or redo actions that could be performed. The menu titles are also not updated for the action to be performed.
  • There is a short delay between clicking on the map and a map pin being placed.
  • When showing pins for all selected locations the red (most selected) pin may be hidden by the pin of another location near by unless the zoom level is such that both locations are slightly separated on the map.
  • when changing the selection to an image that has a location some of the pin may off the map view. In an extreme case only the point of the pin is on the map and can not be seen. If you do not see a pin when you expect to zoom out slightly.
  • The results of a search are not applied to selected images.
  • When pasting a lat, lon into an image the map is not updated to show the new location.
  • When multiple images are selected clicking on the map only applies the location to the most selected image.

Operating Instructions:

See https://www.snafu.org/GeoTag/GeoTag5Help/ for more information.

Run Program. Use the Open command from the menu or ⌘O to select files to modify. You can also drag files from the finder into the table on the left side of the application window. Or you may select images from your Photos Library. File names shown in a light grey color are not recognized as valid image files or are disabled for other reasons. Such files can not be modified. Dragging or opening a folder will add all the files in the folder and any subfolders.

Select one or more images. When selecting multiple images one of the images is considered the "most selected". The name of the most selected image is shown in yellow using a bolder font. The thumbnail of the most selected image is displayed in the image well (upper right portion of the window). Its location (if any) is marked on the map.

Click on the map to set or change the location of all selected images. Existing location can be changed by clicking on the desired location. Hitting the delete key will remove location information from all selected images. You can Undo/Redo image location changes.

Double click the map to zoom in. Option-double click to zoom out. Or use pinch gestures to zoom in and out if using a touch pad.

Five map styles --- Standard, Imagery, Hybrid, Standard with traffic, and Hybrid with traffic --- are supported. Right click on the map to select the desired map style. If you find yourself working in a specific area of a map you can save the location and zoom level by right clicking on the map and selecting Save map location. When GeoTag is launched the map will load to the last saved location using the last map style selected.

You may cut or copy location information from a single image and then paste that information into one or more images. If you make an error you can undo/redo your changes. You can undo all changes to all images by selecting "Discard changes" from the "File" menu. All Undo/Redo information is cleared once changes are discarded or saved.

The original versions of images that have been updated are saved are in a backup folder. The backup folder may be changed using GeoTag Settings. The first time GeoTag is run it will prompt you to select a backup folder. Images updates can not be saved until a backup folder is selected or backups are disabled (not recommended).

Cut, Copy, Paste, Delete, and Clear Image List can be accessed from a pop up menu by right clicking on an entry in the list.
