How to Find GPS Coordinates in a Photo
· 4 min read
Short answer
To find GPS coordinates in a photo, open the file’s metadata: swipe up in iPhone Photos, use Properties → Details on Windows, or the Preview inspector on macOS. When present, the coordinates identify the camera position to within a few metres.
A geotagged photo carries the single most precise location signal available anywhere in an image file. Nothing derived from the picture itself comes close — and that precision is exactly why the coordinates are worth understanding rather than glancing at.
Where are the coordinates stored?
In the GPS tag group of the photo’s EXIF block, written by the phone at capture. The main tags are GPSLatitude, GPSLongitude, GPSAltitude and GPSDateStamp. Latitude and longitude each carry a reference tag naming the hemisphere; altitude’s reference records above or below sea level instead.
Coordinates can also be duplicated into a second metadata block — EXIF, IPTC and XMP explains which one to trust when they disagree. The hemisphere references matter more than they look. Latitude is stored as a positive number plus a separate N or S marker, so a tool that reads the number and ignores the reference will place a photo in the wrong hemisphere entirely. The full tag structure is described in the EXIF guide.
How do you read the degrees-minutes-seconds format?
EXIF stores coordinates as three numbers: degrees, minutes and seconds. To convert to the decimal form maps expect, divide minutes by 60 and seconds by 3600, then add both to the degrees.
A worked example: 48° 51′ 30.2″ becomes 48 + 51/60 + 30.2/3600 = 48.8584. Combined with a longitude of 2.2945 that is the Eiffel Tower, and the two decimal-degree numbers are what you paste into any mapping service.
How do you check the coordinates on each platform?
iPhone: swipe up on the photo in Photos and tap the map. Android: the info panel in Google Photos. Windows: right-click, Properties, Details, scroll to GPS. macOS: Preview, then Tools → Show Inspector → GPS.
- Step 1iPhoneSwipe up on the photo. If a map appears, tap it for the place name; the coordinates themselves need a metadata viewer.
- Step 2WindowsProperties → Details, then scroll to the bottom of the list. Latitude and longitude appear as separate rows in degrees, minutes and seconds.
- Step 3macOSOpen in Preview, press ⌘I, and select the GPS tab. This one shows decimal degrees directly, plus a small map.
- Step 4Any platform, exhaustivelyThe command
exiftool -gpslatitude -gpslongitude photo.jpgprints both values and does not hide any tags.
If you find nothing at all, the photo has been stripped — which is the normal state of anything downloaded from a social feed. How to view metadata on iPhone covers what a missing map actually means.
Can GPS coordinates in a photo be wrong?
Yes, in two different ways. The receiver can be inaccurate — indoors, in cities, or with a poor satellite fix — and the tags themselves are writable, so any coordinate can be edited or fabricated after the fact.
That second point is the one people underestimate. EXIF is evidence of what a file claims, not proof of where a camera was. For anything consequential, check that the coordinates agree with what the photograph actually shows.
What does the altitude tag tell you?
GPSAltitude records height above or below sea level, with a separate reference byte for which. It is the least reliable GPS field on a phone — errors of 10 to 20 m are ordinary even when the horizontal position is good.
It is still occasionally decisive. A photograph claiming to be at sea level with an altitude tag reading 800 m is telling you something, and altitude is the field people forget to edit when they fabricate coordinates.
Frequently asked questions
- Why does my photo have no GPS coordinates?
- Either location services were off for the camera, the photo passed through a platform that strips metadata on upload, or it is a screenshot. Screenshots are new images and never inherit the original coordinates.
- How accurate are photo GPS coordinates?
- Typically within a few metres outdoors with a clear sky view. Accuracy degrades sharply among tall buildings and indoors, where a phone may fall back to a network-derived position hundreds of metres out.
- Can I put coordinates into Google Maps directly?
- Yes, once converted to decimal degrees. Enter them as "48.8584, 2.2945" in the search box. Degrees-minutes-seconds also works if you include the °, ′ and ″ symbols.
- Do photo coordinates record where the subject is or where the camera was?
- Where the camera was. A photo of a mountain taken from ten kilometres away is tagged with your position, not the mountain’s — a distinction that matters when reading landscape shots.
