Travel companies use drones to maximize the tourism potential of an area that is popular to all tourists.

A local government unit sometimes restricts the use of drones when there is an ongoing military conflict. Drones are also blocked from entering a restricted zone such as military facilities that are conducting experimentation and active military training inside their camps. These growing restrictions prompts drone users to consider the rules and regulations of drone usage to a certain area so that they will not be subjected to either ethical or legal violations. User violators are at risk for legal apprehension that could mandate them to pay for financial compensation or imprisonment for several days if caught violating laws.

Drones can Fly: Drones were usually land dwelling devices as their function are only limited on land navigation. Today, a flying drone is the new face of aerial technologies that are easily operated by any individual. A user launches the elevation of from the ground through a push-button technology to activate the propeller engine to air lift itself from the ground to reach the vast atmosphere above.

Drones can visualize the horizon as they rise higher into the atmosphere while human users control them. Flying is a dominating characteristic of an object because it has the capacity to rise above the land by means of elevating the device from the ground. Used as Logistics: Transportation corporations and online retail companies are opting for drone as part of their logistics, which is an innovative way to elevate the level up the quality of their services to their clients.

Amazon and EBay are now considering a new futuristic service such as using drones to improve product delivery systems that improve their operational framework. One main reason is to lessen expenditures when transporting a certain product from one place to another. Logistic drones can reach their consumers faster than the traditional human-powered delivery of goods and services. Saves Time: Drones are very convenient for users who want to save more time while covering a scene and navigating above the ground.

The two features of this technology center on providing geographic location estimates or geolocation and time information to a GPS receiver such as industrial-grade GPS-enabled devices and consumer-grade consumer electronic devices such as personal trackers and smartphones. One of the notable advantages of Global Positioning System technology is that it does not require a user to transmit data from his or her device.

Uses and Advantages of Total Station in Surveying

Also, a GPS device generally works independently from telecommunication infrastructures or in other words, it does not consume wireless communication data. However, telecommunication systems can enhance GPS positioning and geolocation and time information. It is also important to note that a key benefit of GPS is that it is free. Aside from the fact that an enabled device does not consume wireless communication data from telecommunication service providers, the entire technology is free of charge without any subscription or license.

Note that there are 24 to 32 satellites in medium Earth orbit tasked to provide GPS services across the globe.

These satellites orbit the globe to ensure full coverage of different areas. Furthermore, having different satellites orbiting at different tracks and at different times improves further the precision of geolocation information. This accessibility has made global positioning system a dual-use technology that benefits not only the U.

Previously Viewed. Unanswered Questions. Wiki User The accuracy of GPS is not high enough to insure accurate placement of survey markers.

Surveying requires measuring from accepted, fixed points for greatest accuracy. Also, the earth's surface is fairly plastic, allowing it to flex and stretch. While these movements are usually quite slow, they can affect survey measurements.

In addition, legal descriptions of properties are usually expressed in measurements relative to accepted survey markers, not absolute latitude and longitude that you would get from a GPS unit. GPS can be a quick and easy augment to surveying, but don't expect the theodolite to completely disappear any time soon. There were no electronics of any kind in the mid s.

For that matter, GPS was not invented until the early s. Asked in Engineering What is satellite surveying? Satellite surveying is a form of land survey that uses location information provided by the GPS satellite system to track the location of each reference point. Asked in Technology There are men around the roads of belfast these days carrying poles with glass domed devices on top They are clearly measuring something - but what?

These are extensively used in civil engineering, road construction and measurement. The dome at the top captures triangulation data from GPS satellites.

Asked in Civil Engineering What are theadvantages and disadvantages of tacheometry as a method of surveying? The advantages are that it is quick and easy to use. The disadvantage is that it sometimes is not as accurate.

Global Positioning System is a system for determining your position on the surface of the Earth. As such, other that for reporting your position, it has little use in communication. GPS is of almost universal use in land surveying, but again, that is not comms.

Asked in Business and Industry What are the advantages and disadvantages of the Height of Collimation method in surveying? One of the major disadvantages of purchasing a cheap GPS system is a possibility that such features as traffic or up-to-date maps could be missing. Another disadvantage is poor reception from satellites in areas with high buildings. What are some disadvantages of gps tracking on my cell phone?

The only real disadvantage is if you fear "Big Brother". The GPS is so that emergency services can locate you in the event you call them. Locating people with GPS in an invasion of privacy. Also, with a GPS locator people start to control others. Finally, with a GPS location system tracking someone the person may start to dislike you. Asked in Civil Engineering Types of surveying in civil engineering?The Global Positioning System or shortly known as GPS, is a revolutionary 20th century space based radio navigation system that provides valuable information to users all around the world like three dimensional position, navigation services, velocity and also time data.

Specifically, it provides data for both civilians and military users. This technology was primary developed for military use, though the vast amount of advantage GPS provides certainly contributed to its expansion so much so today this technology is part of everyday life — it is used in mobile phones, car navigation systems, search or rescue equipment, applications in railroad control, mining, agriculture, environmental monitoring and recently as supporting technique for surveying. The GPS technology was quickly adopted for surveying in the late s and early s because it can easily provide accurate position, including latitude, longitude and height, without the need to determine the angles and the distance between different points, some of the first adopters being surveyors of large companies and corporations like the NGS National Geodetic Survey.

This equipment is also faster when compared with conventional surveying equipment. Because the data collection process is faster, the time for getting final results and making decisions is understandably shorter and all of this is done with the minimum chance for mistakes which are not uncommon with conventional methods, as is the example with the use of the limited line-of-sight, for instance.

Despite all the painstaking traditional work, a single mistake would be enough to impact the whole project without ever being discovered. With the application of GPS in land surveying this is no longer the case and as a result, it improves the quality of work. In the past, surveyors had to make several visits to one site in order to use each and every piece of equipment, going step by step to gather accurate data.

Nowadays, a single surveyor can complete all the tasks in one day, something that took a whole team to do in a longer period in the past. Not Affected By Weather Conditions — Another huge benefit is that the GPS surveying is not affected by weather conditions like snow, rain, high or low temperatures.

Unlike the traditional surveying techniques, the GPS surveying is not affected by constraints such as the line of site visibility between the survey locations. Before, when all sorts of equipment were required, all the weight was certainly slowing the process down. Best of all is their design keeps decreasing, though not at the expense of efficiency or price! In other words, the amount of operational limitations is significantly reduced.

3 Benefits Of GPS Surveying

On the plus side too, regardless of the size of the area, it can be even a large one, the level of accuracy remains the same with GPS technology. All in all, the ongoing modernization and development of the GPS technology as well as its connection with other techniques will make the GPS surveys even more useful and widely adopted worldwide in the near future.
