Reading and Making GPS Maps
GPS maps and GPS technology are inventions of the United States military, as many technological advances tend to be. GPS technology employs the use of several satellites orbiting the earth to send signals to GPS stations around the country and world. The data from these stations can be transmitted to individual receivers such as the type found in a vehicle, cellular phone, or even wrist watch. Many of these devices will display a map showing the user´s current location, and in the case of vehicle units, will display a GPS map with the user´s destination.
To read a GPS map, it is important to understand the orientation of the device displaying the map. A vehicle-based GPS unit, for example, is usually oriented to the direction the vehicle is traveling, and the cardinal directions move much like a compass. The map of a vehicle unit will have a few items on its key to make understanding the map easier, such as markers for the vehicle itself, the destination, and any stops between the starting point and destination.
The GPS map will also have markings such as major streets, side roads, highways, toll booths, and retail locations available for display. Each GPS unit will have different customizable features, and the owner´s manual will help to make the GPS unit easy to set up. Many GPS maps for automobiles or on hand-held devices, such as a cellular phone or palm unit, are usually very straightforward, with easily recognizable symbols and large print that is simple to read and follow.
Most folks are probably more accustomed to reading GPS maps than they realize. For example, whenever a person is looking at a map for directions or for general orientation, or on the Internet for similar information, they are looking at a GPS map. Google Earth, for example, uses GPS maps of the entire planet to give directions, and in some areas can display pictures right down to individual neighborhood streets or even homes. Yahoo maps are also GPS generated, and are able to provide easy to follow direction to places with just an address.
Making GPS Maps
GPS maps are made by correlating the photos of the earth by satellite, with known maps, and comparing those to the life satellite feeds in correlation to set point on the earth. For someone wanting to make a custom map, one only needs to utilize a GPS receiver that is mapping grade. A mapping grade receiver can accurately chart a location to less than three feet, and can be ideal for surveying land and other activities that require on-site mapping.
Gps maps
When you first purchase a gps system, often they come pre-loaded with gps maps. The problem with the pre-loaded maps is that they often lack details that you desire or they are not for the locations that you need. You have a lot of options when it comes to gps maps that you can download to your new gps device. If you will be traveling to a specific place, you will want a detailed map of that location so that you can fully utilize your gps system while you are traveling.
Most gps systems are used as navigation aids to use when you are driving. Basically, they are electronic maps that replace those wonderful paper maps that we are all used to using! Having a gps system as a navigation aid makes travel easier and more enjoyable, plus it makes your driving safer allowing you to arrive at your destination with a minimum of problems.
There are various software programs that you can buy to download gps maps to your gps system, but what is even better is that there are places online that allow you to download gps maps for free. Of course, you will need the required cables for your computer and gps device in order to get the maps from your computer to the gps receiver, but they often come with the unit in the first place.
You can also choose to make your own gps maps, and there are places on the internet that can guide you through this. Making your own gps maps allows you to input specific points of interest that you are interested in. Points of interest include hotels, restaurants, attractions, gas stations, and such. Plus, you can choose to include traffic reports in your gps maps. These can be especially helpful as you try to avoid traffic delays during your trip and knowing where possible traffic problems are via your gps system can be a great advantage.
Another great advantage to having various gps maps in your gps receiver is that the unit is often capable of storing specific destination points. That means that if you make trips to the same locations, previous destination directions will be stored in your gps receiver so that you can recall them later and not have to re-input information on your next trip.
When you own a gps device, you will want to have specific gps maps that show as much detail as possible to make your trips easier and more enjoyable. Take a moment to check out your options and find different gps maps other than what comes pre-loaded with your receiver.
