A Geographic Information System is a computer system for storing, capturing, analyzing, querying, and displaying data which has been geographically referenced. The data which has been geographically referenced describes both the characteristics and locations of spatial features. It is also referred to as geospatial data. The history of GIS is about 4 decades.
Websites such as map blast, mapquest, provides fast and simple maps. On these maps, the users can type in points of interest and location address to obtain the desired result, for example, data about nearby churches and schools.
The following are the applications of GIS
During dry periods, wetlands retain water and contribute to a healthy environment, thus keeping the water table relatively stable and high. They act to reduce flood levels during the flooding and to trap attached nutrients and suspended solids. GIS mapping software provide alternatives for wetland mapping and quickly design projects for conservation of wetland with the assistance of GIS. A combination of Remote Sensing data aids the completion of wetland mapping on different scale. Through the use of GIS map spices, information can be used to create a wetland digital data bank.
Management of Natural Resources
Through the help of GIS software applications, the water, agricultural, and forest resources can be well managed and maintained. Forest condition can be easily monitored by foresters. Agricultural land includes monitoring crop rotation, managing crop yield, etc. Water is one of the most vital constituents of the environment. The geographical distribution of water resources can be analyzed with the use of GIS. They are related to each other, i.e. tree canopy stores about 215,000 tons of carbon, and forest cover lowers the storm water runoff. GIS is also applied in aforestation.
This provides resourceful information about a particular area. It helps in understanding the suitability of soil for different land use activities. It is vital for the prevention of environmental deterioration related with the wrong use of land. GIS aids in identifying types of soil in an area and to clearly describe soil boundaries. It is used for the classification and identification of soil. Soil mapping is widely used by farmers in advanced countries to earn maximum yield and retain soil nutrients.
The other uses include, transport applications, emergency, crime analysis records management, planning, land market analysis.
The combination of GIS software with wireless technology, global positioning system (GPS), and the internet has led to the introduction of new and amazing applications. In-vehicle navigation system, vehicle drivers can locate the shortest possible routes.
The rise in demand for spatial data technology can only be satisfied with the use of computers. GIS is a representation of the simplified perception of the earth.
A GIS, unlike the traditional paper maps, can offer detailed information of features such as streams, buildings, roads, etc. In addition, the computers can quickly analyze and search the features of a map and their attributes. These advantages cannot be gotten from traditional maps.
All the data objects are represented by lines, points, and areas. Each of the spatial data has the intrinsic coordinate value.
Using GPS can be difficult for those who do not refer to the handbook and are not really aware of the functions the device has to offer. Read the instructions and explore the device before using it for the purpose it is meant for…find out how!
GPS is an acronym which is short for Global Positioning System and is a modern tracking system based on the location of over thirty satellites which have been sent into space over the past fifty years, mainly by the US military. A GPS device can calculate its own location or, in fact, the location of any given building or address, using only the signals sent to it from the GPS satellites. The whole satellite idea was inspired by the USSR who was the first to send one into space, but the US came up with the idea of GPS and perfected the system, which probably made them quite proud since that happened in times of the Cold War. In fact, civilians haven’t been able to use it for long, and it was long reserved for the military and the navy, but with technology like this, it is no wonder that when they were allowed to use it, the news about the devices spread like a virus, and nowadays, most cars and cell phones are equipped with GPS. Since 2000, the GPS system that civilians can use is just as efficient as that of the US military, which made it even more interesting to use.
Using GPS Features
A GPS Feature Checklist.
Nowadays, a GPS device will have a lot of features to it. In fact, it is a quite and useful technology that you can use for more than one thing. This is why there is more than one type of GPS device. GPS devices can be automobile navigation systems, they can be a simple cell phone with a GPS function in it, or they can be aimed at a very specific group of users, like GPS devices made to be used for hiking or sailing, so the user always knows their location and can also be found in case they get lost, which is not unlikely when practicing such a sport.
Whatever the device may be, this is some advice that goes for any GPS gadget and in fact anything technological that you buy. First, don’t be afraid to ask the shop assistant for help. If you are knowledgeable about the topic, ordering off the internet is quicker and more comfortable, but if you have no clue where to start, you’ll be quick to make a mistake online and order something you didn’t need or want in the first place, thus wasting your hard-earned money. If you are unfamiliar with what you want to purchase, it is better to take out the time and go to a shop. Approach an assistant, state what kind of device you want and what you want it to be able to do, and hopefully he or she should come up with something. Remember though that most shop assistants do get a sales commission, so make sure you really need all the features of the gadget they recommend you, and also that there isn’t a similar model at half the price one shelf below the one recommended to you. Think; if you will be using the GPS for sailing, a water-proof device might be good but you would not necessarily need a glow-in-the-dark device to use in your car.
Basic Rules of GPS Devices
Once you have bought the device, it might be a good idea to open the handbook and read it. True, a lot of functions you can guess, but you might also miss out on some by just trying to work things out on your own. As a basic rule, most devices with a GPS will be able to tell you where you are when you press some button or other. They will also be able to tell you where something else is if you tell them what you are looking for by typing it in. Other functions will depend on the system. For automobile use, it is likely that you will be able to switch to 3D view, for example, or look for a certain type of business located near the place you are in. A marine GPS, to be used when sailing, might provide information like water depth or other characteristics. Most GPS systems are also able to measure distances. Know what your gadget can do, then all that is left is making use of its full potential.

What is the technology they use? Nothing more than the satellites! They synchronize with the 24 operational satellites and fix up some errors arising out of the obstacles which are either man-made or natural. Find more below…
GPS is short for Global Positioning System, and that captures well what it does: it indicates your position on the globe. The way GPS operates is a fascinating tale that doesn’t require advanced mathematics to understand.
Before looking into the details of how navigation systems work, it’s helpful to have some general knowledge of how certain positions on earth are specified. The classic view provides one that’s easy to visualize.
Imagine a simple grid that wraps the globe ‘vertically’ originating at the earth’s North Pole and stretching out over to the South Pole. Then add ‘horizontal’ lines that cross the globe at right angles to the vertical lines. That grid is the familiar longitude and latitude ‘mesh’ that can be found on every school room globe and map. Each line of lat and long is divided in degrees that specify how far along a line you are located.
Now, what does the ‘mesh’ have to do with the GPSes system?
The U.S. Air Force maintains 24 different operational GPS satellites (with 3 spares). Each satellite has the electronics and software installed to calculate its own location, most importantly the distance to the Earth. It does that by sending a radio beam out and registering the time needed to hit the Earth where the signal is picked up by ground stations.
A simple formula is: distance = velocity * time, and that describes it pretty straightforward. Radio waves travel at the speed of light (~186,00 mph or ~300,000 kph) and the electronics measure the delay from when the beam is sent to when it hits the target.
Satellites (and ground stations) can measure that delay accurately because they have computers synchronized by atomic clocks that are able to measure time incredibly accurately. GPS Receivers don’t have atomic clocks included but perform some tricks to compensate.
Also because of variations in the atmosphere, the motion of the satellites, reflections from buildings, and other imperfections GPS have to make up for small calculation errors in order to get the precision needed to locate your GPS receiver to within a few meters.
Distance provides only one important factor in GPS. Imagine you’re told you are 600 miles east of Los Angeles. That puts you in the center of a circle of radius 600 miles, with LA somewhere on the circumference (the rim). But you don’t know exactly where. Now you’re told you are also few hundred miles north of Las Vegas and another circle is created. Those two circles intersect at two points. A third intersecting circle will place you at exactly one unique point (to within measurement accuracy).
Satellites and GPSes Receivers
Since the GPS system is dependent on satellites in space that interact with ground stations, it operates in three dimensions, not just the two provided by the surface of the Earth. So, the Global Positioning System works with spheres rather than circles. The calculations are more complex, but the idea is the same. Where the surfaces of four spheres intersect they calculate a certain point, the location point of the GPS device.
Your GPS receiver is designed to ‘listen’ for the signals from four of those satellites and uses the info provided to determine your latitude and longitude. It overlays that unique point onto a map that resembles your surrounding area to help you to navigate your way to anywhere in the world.

I never realized just how helpful would a personal GPS tracking device be. A personal GPS tracker is very useful in case you hike often to remote locations. I utilize it on a regular basis when I go in foreign countries given that I’m one who likes discovering new places on my own with solely the help of a GPS unit and compass. I likewise carry it in my automobile regularly as a safeguard in case my motor vehicle gets taken. I furthermore know some individuals who utilize a personal GPS tracking device to enable them to spy where their spouse or kids are going. I’m not really indicating this is the correct thing to do, but it is actually beneficial to know that you may likewise utilize a personal GPS tracking device in this manner.
GPS covers a large area of communication concept. Understanding it is very difficult. But here a brief idea is given about it. After reading it one can understand what is GPS is all about. But still many information is there to know about it.
I saw a segment about the Global Positioning Satellite Devices in space and according to Stephen Hawking’s, Into the Universe, the effects of time goes slower closer to earth than in space. Gravity has an effect on time in which it slows time down. So basically, these GPS satellites are “getting older” faster than objects/humans on Earth.
