Geolocate from pixels

Every photograph taken outdoors contains enough information to place it. The constraint is never the image; it is your patience and your reference knowledge.

The beginner mistake is searching before inventorying. People see a mountain, type "mountain with two peaks" into a search box, and get nothing. The method is the opposite: extract every clue first, rank them by how much of the planet each one eliminates, and only then start searching — because the clue that pins the country is usually not the one your eye went to.

Rank your clues before you search

Work down this list. Each row eliminates far more of the world than the one below it, so a single row-one clue is worth twenty row-six clues.
