Geocaching is an activity in which participants use a GPS to navigate to a predetermined location where other participants have left some sort of trinket for people to find. It can be something simple or some thing of sentimental value. The point is coordinates are used for the location of the object that is in question and is used to locate it.

It could be valuable in environmental research in pinpointing certain locations that might be of environmental interest. For example, using coordinates to identify certain spots, one could identify a particular tree that might be worth studying due to its exposure to pollution. Other examples could be certain places where core samples were taken or where water contained certain toxins.
