GPS Maps - How Important Are They?

Aug 18, 2007
Many people have heard about a GPS map but not many people realize what they are or how they work. Most of the time, only people who have traveled extensively such as pilots, navigators, sailors and similar people would be most acquainted with GPS maps because this kind of new technology is very essential in regards to charter courses when you travel.

However, the military, researchers and various other people who would have the need or desire to be aware of their exact locations at any given time are also utilizing this kind of technology. On the other hand, for the majority of ordinary people who would not want or need to know about any systems or maps that could let them know exactly where they are at any given point in time, GPS maps are not as well known.

Exactly what is a GPS Map?

GPS is an acronym that stands for Global Positioning System, this system is a global radio navigation system that is comprised from the interaction of 24 satellites orbiting the Earth, along with their corresponding ground stations. In the distant past, navigators and sailors would depend on the stars to point them on their way to their destinations. Fast forward to the present, through the use of modern technology of a GPS map, travelers such as sailors, pilots and those who travel by land no longer have to use the stars to guide them.

A GPS positioning system utilizes the orbiting satellites as reference points in determining the distance from one point to another and to find certain objects on the planet. With the use of satellite data, it would be fairly easy to calculate the distance of a certain place to another place.

The technology has become so advanced and precise that it can calculate your position exactly down to the centimeter. For instance, if you are using a GPS device to find a certain area anywhere on the globe, it can pinpoint precisely where that area is and what the distances is from where you are standing. The exact nature of the technology within GPS systems is such that when we refer to a GPS map, we can rest assured that the information we can find within these GPS maps are easy to follow and accurate.

Everyday uses for GPS Maps

The GPS map has too many uses in our current society. For one, the police department can help fight crime by using a GPS map; by installing a GPS vehicle navigation system in police cars, the police officer can easily respond to alerts in the city. GPS maps give police and other government services the ability to find a way around the city just as if they know every corner and every street by memory alone.

Because the technology has progressed to the point where it can find a location down to just a few feet it has been utilized extensively by the military as well. When you see the documentaries on TV showing a "smart bomb" strike a target with pinpoint accuracy what you are seeing is GPS technology in action. What they do is incorporate an on board GPS navigation system into the missile to guide it to its target.
