Iran - Kish Island GPS Map

Kish Island GPS Map

There are different types of maps; the traditional paper map, an internet generated map and a GPS map. Amongst all these, a GPS map is perhaps the most versatile and updated one. A GPS device is as good as the mapping information it holds. Thus GPS navigators come with basemaps and several points of interests that indicate the locations of gas stations or hotels. A GPS receiver comes preloaded with the detailed and most updated map information of a specific region or country. In case you need any additional data, you can always download it to your device. A few advantages a GPS map has over the others is stated below :

Advantage I: Most Up-to-Date

Unlike the traditional paper maps or an internet generated one, the GPS map is the most up-to-date one. This is because although, the device comes with preloaded maps of certain region, you can definitely download the latest version of the maps directly into your unit from the mapping website. Also the sat nav manufacturers ensure to have the most recent versions of maps on their site, wherein you get the detailed mapping data absolutely free of cost.

Advantage II: It provides the facility to personalise the map
Paper map and internet generated maps can also be customized to suit your needs. However you will need a marker to mark the locations of gas stations or trace your best hiking route. Once you use a marker or highlighter on the map, it is permanent and next time you want to mark something, you either need a new map or a different colour marker. Eventually you might have either spent a great deal on buying a new map everytime you visit a new place or there would be so many markings on your map that it would appear shabby and unreadable.

This is where GPS maps are useful. All you need to do is create a separate folder and save the data in the specific folder after every trip. You can later even make alterations or changes to it, as per your convenience and choice. The maps are in no way rendered unreadable. Saves you loads or time and money as well.

Advantage III: Easy to Trace Back
With a GPS map you can easily trace back your steps. This is because the device has the capability to track your progress, thus by just selecting the right buttons, you can easily get a complete history of the route taken, makes it simple to re-trace your steps. Although, this can also be done by using the paper maps, it is a little tedious and cumbersome procedure.

The above stated points are some of the reasons why users might prefer a GPS map from a traditional paper map. If you too need to reap the benefits of GPS maps, then just go and grab a satellite navigational unit that has the latest and updated GPS maps and plan your travel to unknown and unfamiliar cities.

GPS in boat

The GPS systems (Global Positioning System) are used for determining the exact location of on object in the earth and this system can be used when traveling in a boat. When a satellite sends a signal the GPS receiver picks up these signals and gives us the exact location. The accuracy of this system is pin point and will never go wrong.
There are many satellites that transmit signals simultaneously, but the GPS receivers do not receive these signals. Seeing as that the distance of each satellite from the reception unit will be different. By knowing the speed of light, speed of signal and the transmission rate the receiver can calculate the exact distance to the satellite.

It was earlier used for military purpose and in 1993 it was available for civilian use. These systems were degraded and thus affected its accuracy. Other factors affecting the accuracy of GPS in boat navigation depends on the speed of the boat, strength of the signals and environmental factors like geomagnetic and gravitational forces.

Signal strength depends on the distance of the satellite to the receiver, at the beginning the GPS system evaluates all the signals and selects the best 5 nearest satellite signals for navigation.
Advanced satellite navigation system called as Chart plotter can be used in boat navigation for determining your boats progress. It uses electronic chart display and an information system to display your accurate location in a chart, map or a specified area.

It will also give the distance to the nearest land or shore. To find the best and easiest route to a specific destination one can connect this GPS system to the boat radar. This will give you the track line or the way point to your destination.
