Difference Between DGPS And GIS. In this article, you will come up with information on what is DGPS, what is GIS, and what is the main difference between DGPS and GIS. Both the terms are interrelated to each other, but there is a difference between them. Let us differentiate between DGPS and GIS.
What Is The Main Difference Between DGPs And GIS?
The main difference between DGPS and GIS:
-DGPS stands for ‘Differential Global Positioning System’. It is the advancement in GPS that gives us more accuracy in determining the location.
-GIS stands for ‘Graphic Information System’. It is a device that is responsible for capturing, storing, displaying, and checking the information that is related to the positioning of the surface of Earth.
What Is DGPS?
DGPS stands for ‘Differential Global Positioning System’. It is the advancement in GPS that gives us more accuracy in determining the location, from the 15-meter nominal GPS accuracy to about 10 cm for best implementations. Satellites in space provide signals to the surface of Earth. These signals travel at the speed of light. The error can happen due to the atmospheric pressure. These errors are adjusted by DGPS to provide an accurate position. DGPS systems are used in the fixed ground-based reference stations. It is used to know the different positions between the fixed positions and the GPS satellite system.
What Is GIS?
GIS stands for ‘Graphic Information System’. It is a device that is responsible for capturing, storing, displaying, and checking the information that is related to the positioning of the surface of Earth. You can view various kinds of information on a single map with the help of GIS. There are various kinds of uses of GIS like;
-Ease in understanding the patterns and relationships between geographic systems.
-Compare the locations with each other
-Tells the places present on the location that are sensitive to pollution, so you can take precautionary measures.
