Navigation Signs and Routes

Landmark or Waypoint
The coordinate value of a point saved in the GPS memory. When there is a GPS signal, click the “MARK” button and the current point will be recorded as a roadmap. It has a default name which is generally like “LMK04”. You can change it to an easily recognized name (letter Use the up and down arrows to enter, and you can also select an icon for it. Signposts are the core of GPS data and they form the basis of the "routes" (see 3). Marked signposts are one of the main features of GPS, but you can also read the coordinates of a location from the map, enter GPS manually or through a computer interface, and become a signpost. A signpost can be used for future GOTO features (see 5). It is also possible to select a route, see 3. ) As a fulcrum. General GPS can record 500 or more road signs.

Route (ROUTE)
A route is a set of data stored in the GPS memory, including the coordinates of a starting point and an ending point, and may also include the coordinates of several intermediate points. The line segment between each two coordinate points is called a "leg". The common GPS can store 20 lines, each with 30 "legs". Each coordinate point can be selected from existing landmarks, or the manual/computer input values. The input waypoints are also saved as a Waypoint/Landmark. In fact, all the points of a route are references to a road sign. For example, if you change the name or coordinates of a road sign under the signpost menu, if a route uses it, you will find that the route has also undergone the same changes. . There can be a route that is "Activity". The waypoint of the “active” route is the goal of the guidance (see 5).
