What is Photo Geotagging?

Geotagging means embedding GPS coordinates directly into your photo files. When a photo has location data, you can:

Find photos by where you took them — "show me all photos from Rome"
See your photos on a map in Apple Photos, Lightroom, or Google Earth
Organize your archive by location, not just date
Preserve the memory of where you were — years later, location helps recall more than timestamps

Geotags live in the EXIF and XMP metadata of your image files. They're permanent, portable, and work across all apps.

Everything you need to get started with photo geotagging

The fundamentals: GPS coordinates, EXIF/XMP metadata, and why location data matters for your photos.

Two reasons it matters: archival organization and storytelling with maps.

Step-by-step guides for every method: GPX tracks, reference photos, and manual placement.

Your fancy camera doesn't have GPS? Here's how to add location data to those shots.

How to record and use GPS tracks to automatically geotag photos by timestamp.

Geotagging photos in your Photos library and the difference from Apple Photos locations.

Apple Photos "Locations" are not the same as real GPS geotags. Here's why it matters.

GPX, NMEA, and other formats explained — what your GPS device can output.

Your DSLR or mirrorless camera doesn't include GPS for good reasons. Here's the tradeoffs.

Geotagging turns photos into journeys — visualize your travels on a map.

Export your geotagged photos as a KMZ file to explore on Google Earth or share via Google My Maps.

HoudahGeo is the Mac app that makes geotagging easy — matches photos to GPX tracks, writes EXIF/XMP metadata, and exports to Google Earth.
