WAAS
WAAS stands for Wide Area Augmentation System, but that doesn't really describe what it is.
Watch List
A watchlist is a list of users that are watching a specific travel bug or cache. Each user receives a copy
of each posted log via email.
Waypoint
A waypoint is a reference point for a physical location on Earth. Waypoints are defined by a set of
coordinates that typically include longitude, latitude and sometimes altitude.
Every geocache listed on our website is a waypoint. Geocaching.com generates a unique "GC Code"
associated with every geocache listing.
Webcam Cache
This is one of several cache types which are no longer available for creation on Geocaching.com.
These are caches that use existing web cameras placed by individuals or agencies that monitor
various areas like parks or road conditions. The idea is to get yourself in front of the camera to log your
visit. The challenging part, however, is that you need to call a friend to look up the web site that
displays the camera image. You will need to have them to save the picture to log the cache. If you are
a tech savvy, you can also use a wireless modem and save the image yourself on a laptop.
WGS84
The most current geodetic datum used for GPS is the World Geodetic System of 1984 (WGS84). The
significance of WGS84 comes about because GPS receivers rely on WGS84. Geocaching uses the
WGS84 datum by default. We also use the format HDDD MM.MM, which is a standard for GPS
receivers. HDD means Hemisphere and degrees. MM.MM are minutes in decimal format. It is critical
that the format be correct, otherwise geocachers will be unable to find your cache!
Wherigo™ Cache
This is one of several cache types. Wherigo is a toolset for creating and playing GPS-enabled
adventures in the real world. By integrating a Wherigo experience, called a cartridge, with finding a
cache, the geocaching hunt can be an even richer experience. Among other uses, Wherigo allows
geocachers to interact with physical and virtual elements such as objects or characters while still
finding a physical geocache container. A Wherigo-enabled GPS receiver is required to play a
cartridge.
