How to Check a Photo's GPS and Timestamp Data

You assume your field photos carry their location and time. Most of the time, they do. Then you open one from an important visit and the location is blank, and you have no idea whether it was ever there.

You can find out in under a minute, on any device. You can also test your whole process before a site visit, so you never have to learn this from a client's question.

This guide shows you where to look, what removes the data, and how far you can rely on it once you find it.

How do you check a photo's GPS and timestamp data?

Open the details of the original file. On iPhone, swipe up on the photo in the Photos app. In Google Photos, open the photo's info panel. On Windows, use Properties, then Details. On a Mac, use Preview's Inspector. Check the copy that actually reached you, because a forwarded copy may have lost its data.

What's stored inside a photo file

Phones write this data into the image file as EXIF metadata. Your report or software may show friendly labels, but these are the standard fields underneath:

You don't need to memorize these. Just know that location and time are separate fields, so a photo can have one without the other.

How to check on an iPhone or iPad

Apple's steps are simple:

1. Open the photo in the Photos app.
2. Swipe up, or tap the Info button.
3. Look for the date and time, the place where it was taken, and the camera details.

If a location shows up, you can tap it to see it in Maps. Only photos with embedded location data appear in the Photos map view, which makes the map a quick way to spot photos that have none.

One thing to watch: the same panel lets you edit the date, time, and location. What you see here is what's stored now, which may not be what the camera first recorded.

How to check on Android

Steps vary by phone and gallery app. In Google Photos:

1. Open the photo.
2. Open its info panel. Depending on your version, swipe up or tap Info or Details.
3. Look at the date and the location section.

Google Photos adds a wrinkle that matters in the field. It can show a location it estimated, as well as one the camera recorded. An estimated location isn't the same as a location your camera recorded at capture. If location really matters, confirm it in the file itself using a computer. On a Pixel, the camera's location setting controls whether new photos record location at all. Other brands have a similar setting in their camera apps.

How to check on Windows or a Mac

A computer gives you the most reliable view, since it reads the file directly.

Windows:

1. Right-click the photo in File Explorer and choose Properties.
2. Open the Details tab.
3. Scroll to Date taken under Origin, and Latitude and Longitude under GPS.

Mac:

1. Open the photo in Preview.
2. Choose Tools, then Show Inspector.
3. Open the More Info tab, then look at Exif for the date and GPS for the location.

For a batch of files, the free command line tool ExifTool can read every field:

exiftool -GPSLatitude -GPSLongitude -GPSImgDirection -DateTimeOriginal -OffsetTimeOriginal photo.jpg

The two-minute test to run before your next site visit

Checking one photo tells you about one photo. This test tells you whether your whole process keeps the data. Run it once on each phone, and again when anything in your process changes.

1. Take a test photo outside, with location on for your camera.
2. Check it on the phone. Confirm the time and location appear.
3. Send it the way you really send photos. Text it, email it, AirDrop it, or upload it, whatever your team does.
4. Check the copy that arrived, on a computer. Don't check the original again.
5. Take a screenshot of the photo and check that too. This is your control. A screenshot is a new image and won't carry the original photo's location data. If your tool shows a location for it anyway, that location came from somewhere else.

If the copy has lost its data, you've found the leak while it's still cheap to fix.

What removes GPS and timestamp data

Treat this table as a list of things to test. Results can change with app versions and settings.

The pattern is simple: the closer you stay to the original file, the safer your data. Avoid sending field photos through chat apps as your main route, and keep the originals until you've confirmed they arrived intact.

How accurate is a photo's GPS location?

Close, but not exact. According to GPS.gov, GPS-enabled smartphones are typically accurate to within about 16 feet under open sky, and accuracy gets worse near buildings, bridges, and trees. Indoors and underground, you may get a poor location or none.

On a real site, that means:

• A pin may land on the wrong side of a narrow building or in the next room.
• Coordinates can show that a photo belongs to a site, but they won't tell you which unit, floor, or side of a wall it shows.
• Compass direction is an estimate too, so treat camera bearing as approximate.

That's why captions still matter. Your caption carries the precise location, and the coordinates support it.

What about the timestamp?

The capture time comes from the device, so it's only as good as the device's clock. Keep these points in mind:

• Automatic time is your friend. Set your phone's date and time to automatic.
• Dedicated cameras drift. Many have clocks you set by hand, and those can be wrong by hours or more after a battery change or a trip.
• Time zones can confuse people. If a file has no time zone field, a tool may show the same clock time in any zone. A photo taken on a job in another state can look an hour or more off.
• A file's "date modified" is a different thing. Copying or editing a file can change it. Look for the date taken instead.

What photo metadata can't tell you

Metadata is a useful record of what a device reported, but it isn't proof by itself. Three limits are worth knowing:

It can be changed or lost. The Scientific Working Group on Digital Evidence notes that metadata "can be limited, absent, or altered." As shown above, ordinary phone menus can edit a photo's date and location.

It doesn't say who took the photo or what it means. It records a device, a place, and a time. It can't confirm who was holding the phone or whether the scene was represented fairly.

It usually needs a person behind it. In US federal courts, Rule 901 asks for evidence that an item is what you claim it is, and testimony from someone with knowledge is one way to provide it. This is general information, not legal advice, so talk to a lawyer about how it applies to you.

So how do you build a record that holds up better?

• Keep the original files, unedited.
• Move photos into the project record soon after the visit.
• Write captions while your memory is fresh.
• Note who took the photos and when.
• Use one consistent process across your team, so unusual files stand out.

Our glossary entry on chain of custody covers why that trail matters.

How Vortyk handles this data

Vortyk reads GPS coordinates, camera bearing, and capture time from each photo when it uploads, so nobody types them in by hand. Your original file isn't modified. Each photo appears on a map, and PDF photo logs print the coordinates and capture time with the photo.

If a photo arrives without location data, Vortyk still accepts it, flags it for review, and leaves it off the map. You see the gap right after upload, while you can still do something about it. Join the waitlist for early access, or read exactly which fields Vortyk reads.
