• The National Highways Authority of India (NHAI) and the Survey of India are introducing a new satellite-based system to improve road construction.
• The technology, known as Continuously Operating Reference Stations (CORS), provides centimetre-level accuracy for surveying and planning highways.
• This system replaces older GPS methods and allows for real-time, error-free mapping even in difficult or uneven landscapes.
• By using this network, the government aims to finish projects faster, reduce construction costs, and ensure roads are built to higher quality standards.
The National Highways Authority of India is working with the Survey of India to adopt a new mapping technology that will make highway construction more accurate. At a workshop held in Raipur this week, officials discussed the rollout of Continuously Operating Reference Stations (CORS). This technology is designed to fix the accuracy problems of standard GPS, providing the precise measurements needed for large-scale engineering projects across the country. Advertisement
During the event, NHAI Regional Officer Pradeep Kumar Lal explained that using CORS technology will lead to a more modern approach to building roads. He said that having access to high-accuracy data in real-time will help engineers and contractors work with much better precision. This change is expected to help projects meet global standards while making the whole construction process more transparent and easier to track for all stakeholders involved.
Technical experts at the session noted that the CORS network is a steady infrastructure that can provide exact locations anywhere in India. It was explained that applying this to highways will help create digital maps without the usual errors found in traditional surveying. This is especially helpful when working on complicated terrains, such as hilly or forested areas, where older survey methods often struggle to get the right measurements due to signal interference or manual error.
Beyond just mapping, the technology will also help supervisors monitor the quality of work as it happens on-site. Surveyors at the workshop pointed out that because the system is so precise, it helps avoid mistakes that usually lead to expensive and time-consuming repairs later in the project. By getting the measurements right the first time, the authority expects to save a significant amount of money and meet project deadlines more consistently.
Senior officials from the Ministry of Road Transport and Highways also attended the session to plan how this technology will be used nationwide. The plan is to make this high-precision surveying a standard part of all new highway projects under the ministry's oversight. As India continues to build more expressways, using these digital tools is seen as a necessary step to ensure that the work is done efficiently and that the new roads are safe for the public.
