First, it allows you to save your location in the memory of the GPS. Your GPS records two kinds of information that are useful for creating maps or saving the coordinates of a place.

Zoom in and out by pressing the up and down arrow buttons on the left side of the GPS.įurther information where to obtain OSM maps for Garmin devices and how to install them can be found in the OSM wiki If you have added OSM maps to your GPS, you may see roads and places.
In the upper left corner are your coordinates, your latitude and longitude.įlip to the Map page, and you can see a map of where you are. If you return to the Satellites page, you can see that you are connected to three or more satellites. By pressing the X button, you should be able to flip through different screens that will look something like this:.
If you press something by mistake and would like to cancel or go back, press the “X” button. To switch between screens, press the button marked “X”, just above the power button on the right side of the device.
The GPS has different screens and menus that allow you to do different things. Once your location is determined, the Satellite screen will disappear and you will see the main menu. When it has connected to three or more satellites, it will have your location. Your GPS is looking for satellite signals. You should see something like the image below. The GPS will start, and it will show you the Satellites page. On the right side of your GPS, press and hold the Power button. Because the GPS determines your location by receiving signals from satellites, it won’t work indoors. Every place on Earth has unique geographic coordinates.įor example: -8.639298 Latitude, 116.311607 Longitude is a location in Lombok, Indonesia.īefore you turn on your GPS, go outside where you have a clear view of the sky. The second number tells you how far North or South you are – this is called latitude. One number tells you how far East or West you are – this is called longitude. It records this location in coordinates, which are two long numbers. By receiving these signals from the satellites, a GPS is able to calculate your exact location on the planet. What is a GPS?Ī GPS is like a mobile phone, except that instead of receiving radio signals from telephone companies, it receives signals from satellites that are going around the Earth. There are many other models of GPS which do the same thing, so if you are working with a different one, don’t worry – the principles remain the same. Here we will explain how to operate the Garmin eTrex Vista HCx, a common GPS used for mapping. You will learn how to operate a GPS, and how to use it to create maps. In this chapter we will see what a GPS does and how it works. But the other task is collecting the information itself - that is, going out and surveying an area. Learning to edit is one of the key parts of mapping - that is how you add information to the actual map.
