Geospatial technology is a system that comprises of subsystems like GIS, photogrammetry, and remote sensing. These subsystems help in the gathering of geographic information and representing it on a map.
The geospatial technology scheme could be a different entity with multiple interactive parts. Over the years, the technology scheme has evolved to capture the interaction between geospatial technologies, new facultative technologies and business processes to bring with it multitude of opportunities. As geospatial technologies get infused with the new age technologies and acquire embedded into the business processes, they become Associate in Nursing enabler for socio-economic development.
The geospatial technology can be segmented into four different categories, viz. GNSS, Remote Sensing, GIS/Spatial Analytics.
Also known as GPS (Global Positioning System), it is the system owned by the US Government. It is a radio navigation system which is a space-oriented one. As the ‘location’ part becomes pervasive in our lives, GNSS and Positioning technology phase matures and becomes very relevant rising productivity and reliability. Associate in Nursing integrated a part of the management method, GNSS permits high accuracy positioning with the assistance of satellite signals. GNSS and Positioning phase could be a composite of GNSS upstream and downstream markets, the measurement market, and therefore the quickest growing, the indoor positioning market.
According to the GeoBuiz-18 report, the GNSS and Positioning industry is the largest in the geospatial universe. Its market size is observed to be growing at a compound annual growth rate (CAGR) of 13.5% to reach $260 billion in the years 2018 to 2020.
Remote sensing includes the use of sensors mounted on airplanes and satellites. These sensors are functioned to measure the electromagnetic reflections on, above and below the earth using mostly infra-red signals. Remote sensing is used primarily for observation of weather, mineral exploration, yield forecast, and mapping purposes.
GIS (Geographic Information Systems) is one of the most critical systems of the geospatial technologies. It is majorly a computer-based tool that helps in analyzing, storing, manipulating and visualizing the geographic data in a map. It all includes gathering the required geographic data, managing it, analyzing it, and representing it on a map.
To summarize, the ecosystem of Geospatial Technologies is very vast, and every single segment of the system plays a vital role delivering solutions for the citizens, the government and businesses as well. The applications of these types of mapping tools are endless, and they make our lives very much easier which help in essential tasks such as resource planning and traffic management.
