Which application utilizes coordinates for outdoor adventure seeking?

Geocache is the correct answer because it specifically involves the use of coordinates to locate hidden containers or "caches" in outdoor environments. Participants use GPS devices or smartphone applications to receive geographic coordinates that guide them to the locations of these caches, which may contain treasures or logbooks. The interaction with the physical world and reliance on GPS technology makes geocaching a popular activity among outdoor adventurers who seek new locations and enjoy the thrill of the hunt.

Other applications such as augmented reality might use coordinates in a broader sense, but they often focus on overlaying digital content in real-world environments rather than specifically guiding users to physical caches. Online gaming may incorporate location elements but typically operates in virtual environments rather than engaging with physical outdoor adventures. Location-based advertising can utilize coordinates to deliver targeted advertisements based on a user’s physical location, but this does not involve the adventure-seeking aspect that characterizes geocaching.
