How to Geolocate a Photo: A Step-by-Step Guide

Geolocation, finding where a photo or video was taken, is one of the best-known OSINT skills. It is used everywhere from verification journalism to CTF missions. This guide walks through a systematic method you can follow when all you have is a single photo.

1. Check the metadata first

Image files can store information such as the device, the date and sometimes GPS coordinates in metadata called EXIF. If your file is an original, look at this information first.

However, most social media platforms and messaging apps strip location data from uploaded images. In CTF missions metadata is usually removed on purpose too. Do not be disappointed if there is none: the real work is reading the image itself.

2. Read the image piece by piece

Look at the photo not as a whole but as a list of clues. Note every finding and ask yourself: “Which country, which city, what kind of place does this tell me?”

• Text: Signs, shop names, posters. Language and script narrow down the country; phone number formats and domain names (like .com.tr) narrow down the region.
• Number plates: In Türkiye the first two digits of a plate show the province (34 İstanbul, 06 Ankara, 01 Adana and so on).
• Architecture and materials: Cut stone, wooden bay windows, mud brick or a particular era’s apartment style are strong regional signs.
• Road and street furniture: Road markings, traffic signs, poles, barriers and paving stones change from country to country, even from city to city.
• Nature: Vegetation, soil colour and mountains in the background tell you about climate and geography.
• Light and shadow: The direction and length of shadows can be used to estimate the time and direction.
• Street art and unique objects: A mural, a painted electrical box or an unusual statue can sometimes be found with a search on its own.

3. Run a reverse image search

The same photo may have been shared online before, or the building in it may appear in other photos. Try the image in more than one reverse search engine, and search again after cropping a distinctive part (a facade, a sign).

We explain which engine works best when in our reverse image search guide.

4. Narrow down from country to street

Use your clues to target first the country, then the city, then the neighbourhood. As the search area shrinks at each step, the tools you use change too.

• Combinations of objects: Use Overpass Turbo or Bellingcat OSM Search to look for combinations such as “a petrol station next to a mosque, within 200 metres of a bridge” in OpenStreetMap data.
• Satellite imagery: Roof shapes, road curves and open spaces are recognisable from above. The 3D view in Google Earth makes it easier to compare slopes and heights.
• Search engine: Search for the shop name in the photo, a street artist’s signature or a monument together with the city name.

5. Verify with street view

Finding a candidate location does not mean you are done. Try to find the same angle in street view and check that several independent features in the photo (a door, a window, a pole, a building in the background) are in the same place and arrangement.

In many parts of Türkiye, Yandex Maps has wider panorama coverage than Google Street View. Mapillary offers crowd-sourced imagery with a date filter.

6. Take the coordinates correctly

When you find the exact spot, take the coordinate in decimal degrees. In Google Maps, right-click the spot and click the value shown at the top to copy it (for example 41.008240, 28.978359). The first number is latitude, the second is longitude.

In OSINT TR missions you submit the answer as OSINTTR{latitude,longitude}. The acceptance radius is given in the mission description; putting the pin on the back of the building instead of where the photo was taken can put you outside it.

Common mistakes

• Relying on one clue: The same chain store, the same apartment type or the same municipal sign can exist in hundreds of places.
• Missing a mirrored image: Some images are flipped horizontally. If text looks reversed, flip the image and look again.
• Ignoring time: Street view and satellite images may have been taken on different dates; signs change and buildings are demolished.
• Submitting without verifying: Do not waste your attempts; match the spot in street view first.

Practise

The best way to learn the method is to use it. The location missions on OSINT TR are built from real photos with their metadata removed. Try the first mission and follow the steps above in order.
