GPS is a receiver device that collects signals from satellites for precise positioning. GPS helps to collect the data for GIS software for better accuracy in representing the data. They work side by side for modern navigation systems.
What Is the Difference Between GPS and GIS
If you are familiar with modern-day technology, then hearing GPS should ring a bell to your ears. Yet, there is another technology familiar to GPS. That is GIS. Let’s take a deeper look to extract the most out of their differentials.
GPS stands for Global Positioning System. This technology helps to pinpoint your exact location on the earth’s surface. At the same time, GIS is an acronym for Geographical Information System. It is a type of software that helps people analyze the spatial information of geographical data.
The US military first developed GPS technology in the 1960s. But who knew that this technology would go on to revolutionize the world around us. It is now used for navigation in all sorts of devices all around the world.
On the other hand, Roger Tomlinson developed the first GIS technology in 1960 in Canada. But they created the desktop version of the technology in 1986. The GIS technology now uses a lot of data to give spatial information on a geographical 3D area.
How they work
There is a vast network of satellites that surround the earth. These satellites send information to the ground GPS device about their location. The process is trilateration. It uses relay ground signals from space to the GPS receivers in our device.
GIS technology relies on GPS data. It is capable of capturing, analyzing, interpreting & storing data that it receives from other navigation systems. GIS consists of Remote sensing, GPS, Surveying, field data & other devices.
GPS technology is commonly used nowadays to locate a position. If you are going to an unknown destination, then GPS will help guide you to your destination. It will provide the best routes for you.
Map & surveying is also made accessible due to the availability of GPS everywhere. You can send your emergency location for help from anywhere from your smartphone. GPS trackers are also a great tool to prevent theft.
But GIS is a study field of its own. There are a lot of factors that consist of GIS, including GPS & remote sensing data. You can perform spatial analysis & modeling with all these data. GIS can give a visual representation of GPS data.
GIS helps to visualize the data for data mapping. It can show the relationships between different regions from different standpoints. GIS technology has become essential in a data-driven world such as ours.
What is the difference between GIS and remote sensing?
Remote sensing is the method of acquiring information about an object without knowing making physical contact with the object. Remote sensing is excellent in many fields such as geology, ecology, oceanography. You have to study the object from a distance using devices, satellites, or sensors.
GIS is a study of different methods & technologies for navigation & mapping, and remote sensing is a part of its core. The data obtained from remote sensing helps visualize the data through GIS technology. It is a software approach for the data.
Use of GPS in GIS Data Collection
GPS receivers are present on a regular basis for better location accuracy. It gives the geographical coordinates at the location of the device. While GIS is a vast study field requiring a lot of factors. The most important factor should be the reliable data obtained from GPS receivers.
GPS receivers are used to collect accurate geographical coordinates for any location. It has better real-time data. This data contributes a lot to the GIS technology to relate all other data together. This gives a more clearer picture to the user for better mapping & geology.
What Are the Significant Differences Between GPS, GLONASS, and Galileo?
US air force operates GPS, GLONASS is operated by Russia & Galileo by European Union. All these devices are a part of the global navigation satellite system to provide better accuracy of the location.
From a consumer point of view, they share more or less the same similarities for functionality. But one difference between them is that the GPS has better accuracy for mid to low latitudes. But the GLONASS has better accuracy in high-altitude areas. Galileo falls between them.
What Kind of Navigation Technology Does Google Maps Use?
Google map relies on any sort of global navigation satellite system that your phone or device has. It can be GPS or GLONASS, or BDS. Many have more than two built inside the device by the hardware manufacturer.
But the google maps software has the legal notice to work on any GNSS system your device has. There are differences between different regions. But it’s safe to say that the civilian usage of navigational tools has not been compromised. GNSS usage is available worldwide.
Q: Is GIS a device?
Ans: GIS is software where it processes data collected from other devices. It uses other devices’ data & processes them into a visual representation. This helps better understand the layout of the geography.
Q: What is an example of GIS in our day-to-day lives?
Ans: Google map is the most widely used GIS platform out there. However, it doesn’t go through some of the complex geological compositions. It does provide users with an easy-to-use navigational system of their surroundings.
Q: What is the difference between GIS & LIS?
Ans: LIS is the acronym for Land Information System. It focuses on land management. It is a tool for the more extensive GIS navigational system. The LIS solution can be through GIS.
GPS is a part of GIS technology that has changed the whole navigation system together. It contributes to modern-day research for geology, mapping & seismic activities. It shows how much modern-day technology has come to.
