Geo Clue Matcher
Select the visual clues you observed in a photo, writing script, driving side, plates, outlets, signage, biome, and rank countries by how well they match.
The Geo Clue Matcher is the tool for image-geolocation challenges. You select the visual clues you spotted in a photo, and the tool ranks countries by how well their known characteristics match what you observed.
It does not read the image for you. You are the observer: you decide which clues are present, the tool does the matching and scoring against its per-country catalog.
How it works
You choose values across the clue categories below, then run the match. The tool scores every country in its catalog by overlap between your observed clues and that country's known characteristics, and returns a ranked list of the top candidates with the clues that matched and the clues that did not.
Clue categories
| Category | What you select |
|---|---|
| Writing script | Latin, Cyrillic, Arabic, CJK, Devanagari, Greek, Hebrew, and others |
| Driving side | Left-hand or right-hand traffic |
| License-plate style | The plate appearance you observed |
| Power outlets | The socket type visible in the scene |
| Road signs | The signage style you observed |
| Vegetation / biome | The dominant landscape type |
| Vehicle quirk | Distinctive vehicle characteristics |
You do not need to fill every category. Even one or two strong clues will produce a ranked candidate list; the more clues you add, the tighter the ranking.
Country candidates
The tool returns a ranked list of country candidates. Each row shows:
- The country name and code.
- A match score (overlap between your clues and the country's catalog entry).
- The clues that matched that country.
- The clues that were missed (catalog characteristics you did not observe).
A strong-clue image narrows to a clear leader; a weak-clue image presents several candidates you can then rule out with other tools.
The Geo Clue Matcher is a starting point, not an answer. It narrows the search to a short list of countries; confirming the exact location is usually a job for satellite imagery, map search, and reverse-image lookups outside the toolkit.
Related tools
Once the matcher narrows you to a region, the toolkit's other geolocation tools help you pin the location down:
- Geo Map View, plot candidate coordinates on a dark-themed map.
- Geo Meta Reference, browse the catalog of country-specific visual cues.
- Commons Geo-Search, find other people's geotagged photos of a candidate location.
- OSM Feature Finder, search for places that match a set of nearby-feature constraints.
- Horizon Matcher, rank viewpoints inside a bounding box by how well their terrain horizon matches a photo's skyline.

The matcher runs fully locally. The per-country clue catalog is bundled with the application; there is no network call.
