Coordinate Hunt
Read the coordinates, then click the labeled city or geographic feature at that location. There is no click limit.
Same place. Different coordinate language.
Choose a comfortable starting level, then build toward the compact coordinate formats used in aviation and navigation. Every round places the correct city or geographic feature among labeled decoys spread across the map.
- Easy: degrees, minutes, and seconds in the familiar cardinal format, no time limit, and a labeled latitude/longitude grid.
- Medium: all eight display styles, 25 seconds, a light reference grid, corner coordinates, and the 0°, 0° marker.
- Hard: all eight display styles, 15 seconds, and no coordinate guides.
- Click blank map areas to zoom and recenter as often as needed. The challenge is solved only when you click the correct labeled feature.
- Reset zoom returns to the world without restarting the clock.
Latitude and longitude use degrees, not hours. UTM and MGRS are separate grid coordinate systems, so they are not mixed into this activity.

What the formats mean
A degree contains 60 minutes and a minute contains 60 seconds. Easy mode uses the familiar degrees/minutes/seconds (DMS) form. Decimal degrees put the fraction directly after the degree; DDM puts it after the minutes; DMS separates all three. In signed coordinates, positive latitude is north, negative latitude is south, positive longitude is east, and negative longitude is west.
