Satellite navigators are increasingly entering the life of motorists. Thanks to the presence of the device, the driver has the ability to determine his location with an accuracy of several meters, to choose the most optimal route. But in order for the navigator to show the way, the corresponding maps must be loaded into its memory.
Instructions
Step 1
Since GPS navigators are available from many manufacturers, you need to find maps for your particular model. To do this, enter the exact name of your navigator into the search bar of your browser and add the words "download maps" to your request. Among the links that appear, you will probably find the one by clicking on which you can download the maps you need.
Step 2
If the option of searching for maps on the Internet does not suit you or does not give you a result, ask them around in car stores. As a rule, sellers are well versed in navigator models and will be able to choose the maps you need or advise where you can buy them. This method is also suitable for small towns, for which it can be quite difficult to find good maps on the Internet. Demand dictates supply, so shopkeepers try to keep the goods they need in stock.
Step 3
The maps have been found, now they need to be installed on the GPS navigator. To do this, you need to connect it to the computer with a special cable supplied with the device. As a rule, the navigator itself searches for map files on the computer disks and loads them. If the navigator successfully opens the maps and orientates them correctly, then the installation was successful.
Step 4
What if the required card could not be found? In this case, there is only one option - to make it yourself. Any GPS map is just a drawing in a certain format (depending on the navigator model), tied to coordinates on the ground. There are raster and vector maps, the former are more often used in navigators. If you scan a regular topographic map and save the file in *.jpg
Step 5
To create a map, special programs are used - for example, OziExplorer. To accurately anchor the map, you need to enter the coordinates of nine points: four at the corners of the map, four at the edges and one in the center. The program will calculate all other coordinates on its own. It is better to read about how to use the OziExplorer program in detailed articles on this topic.
