In orientation and GPS navigation, it is very often used to enter the coordinates of a known location and save them as a waypoint. Waypoints in GPS navigators are very important as distinctive icons for individual places on your current or future path..
Destination of waypoints, Waypoints, in GPS navigators, features of waypoints, operations performed with waypoints.
The meaning of the waypoints is that by marking the point as the beginning of the path, you can always return to it using the GPS function of the GOTO navigator (Go to), and it is not necessary to go back along the old path.
Waypoints in GPS Navigation.
From the marked set of waypoints during the trip, you can create and build a new route. That is, waypoints created or entered in GPS navigators can be used repeatedly. A special category of points is the so-called point of interest (POI-Point of Interest).
These include monuments, hotels, restaurants, convenient places for spending the night and just picturesque places. Points of interest can be entered into the navigator and used in the future, as they say, for its intended purpose. The collective efforts of tourists created an extensive library of points of interest.
The creation of the current waypoint means its marking (mark), as a result of which its coordinates will be recorded in the device memory, and the point itself will be automatically assigned a three-digit serial number. For clarity, a waypoint can be assigned a name (name) and select the most suitable graphic symbol, pictogram or icon from the list contained in the device memory.
As an example, note that the set of possible characters is quite impressive. A waypoint name can contain up to six alphabetic characters, including space, plus, minus, and underscores. By default, as a rule, a waypoint is assigned a flag with a number as a symbol. When traveling, on your way you can drive and place more than one such flag. Waypoint Characteristics.

Features of waypoints in GPS navigators.
GPS navigator generates a list of waypoints created by the user, sorting alphabetically. This allows you to quickly find the desired point in the list. In addition to the user list of all points noted above, the GPS navigator, upon request, generates a list of Nearest Waypoints with respect to the current location. This can be especially useful when driving along a route when it is necessary to determine, for example, the place of the next stop and the distance to it..
Great convenience when navigating the sea is a special list of waypoints, called Proximity, and providing warning signals when approaching such a point at a predetermined distance. Around such a danger point, shallows, underwater cliffs and the like, a limiting zone is formed in the form of a circle, at the intersection of which a warning signal is generated.
Export-import waypoints in GPS navigators.
Most GPS navigators allow you to transfer created waypoints to another device. So, connecting two Garmin receivers with a special cable and selecting the GRMN / GRMN protocol in the Interface menu of both devices and then the send wpt command, you copy all points from one device to another. To copy to devices of different manufacturers and a personal computer, you can use the NMEA protocol. Of course, it is necessary that one of the devices supports reception, and the transmission of this message to the other.
By NMEA, only the name and coordinates of the waypoint are copied. Supporting information, such as a waypoint icon, depth, height, creation time, comment can only be transmitted using proprietary protocols, such as Garmin or Magellan. This feature allows you to save a lot of time on laborious work on entering coordinates, save data in case the memory of the GPS navigator is reset, free up device memory from points unnecessary in this journey, copying them to a computer and downloading them to the navigator as necessary. Using the appropriate programs of both branded and independent manufacturers, you can create and edit waypoints on a computer, print their list.
You can enter waypoints into some models of GPS navigators manually, although this is tiring. Where manual entry is not provided, you can enter a new waypoint using the existing point, only changing its coordinates and name. You can also use the method of constructing the so-called projection of the waypoint. With this method, a new point is created at a certain distance and in a certain direction relative to the current location or relative to the selected existing point. The distance value and azimuth value of the created point are entered manually.
