GPS is a satellite-based navigation system that provides accurate location and time information on Earth. GIS is a computer-based system used to collect, store, manage, and analyze geographic data.
While GPS and GIS both deal with location and geographic data, their functions are different.
Global Positioning System (GPS) and Geographic Information System (GIS) are two important and modern technologies used to manage and analyze geographical and spatial data.
Typically, we encounter these terms while tracking and sharing locations on Google Maps or other devices. Many people use both the techniques directly and indirectly many times, but only a few understand how they work and what are the main differences between them.
What is GPS (Global Positioning System)?
GPS is a satellite-based navigation system that provides accurate location and time information on Earth. It determines the position of the receiver using signals from multiple satellites.
GPS is mainly used for navigation, vehicle tracking, surveying and location-based services. It calculates the exact latitude and longitude of any location from a network of satellites, providing distance and time data after processing these signals.
What is GIS (Geographic Information System)?
GIS is a computer-based system used to collect, store, manage, and analyze geographic data. This technology allows users to analyze maps and spatial data, presenting useful insights by combining different datasets.
GIS is widely used in city planning, environmental management, disaster response, and business analysis. It can handle maps, aerial and satellite images, and survey data to generate output to make the data less complex and transform it into maps, graphs and charts.
Major differences between GPS and GIS
While GPS and GIS both deal with location and geographic data, their functions are different:
- Processing and data collection: GPS provides precise location data from satellites, while GIS is a system that manages and analyzes spatial data.
- Data Source: The GPS receiver determines position and time through satellite signals. GIS uses different types of geographic data, such as aerial photographs, maps, and surveys.
- Areas of use: GPS is mainly used for navigation and tracking. On the other hand, GIS is used for town planning, urban planning, environmental monitoring and disaster management.
- Real time data: Provides real-time data received from GPS receivers, which is constantly updated. GIS can also incorporate real-time data, but it requires integration with GPS devices to do this effectively.
