How to get your coordinates

Phone map apps: drop a pin or tap your blue dot; the latitude and longitude are shown in the details.
Desktop maps: right-click a spot to copy its coordinates.
GPS devices and photos: look for decimal degrees such as 29.7604, -95.3698. West longitudes in the US are negative.

How the lookup works

Your browser loads the county lines for the states around the point (Census TIGER/Line 2024) and tests which county contains it. If the point is within 500 m of a line, it names the county on the other side.
