Since 2016, Topcon has exclusively provided the National Land Survey of Finland (NLS) – or Maanmittauslaitos – with its high-precision geomatics solutions, enabling the organisation to maintain the highest possible standards of work and data production. Now, recent tests carried out by NLS have proven Topcon’s GNSS receivers to be the most effective on the market, with the results seeing Topcon retained as the sole provider for at least another year.
What is the National Land Survey of Finland?
The National Land Survey of Finland is an official body that performs cadastral surveys, maintains information about properties and dwellings, handles registrations of titles and mortgages, produces map data and promotes the research of spatial data. The organisation is responsible for various national geo-data services online and at various service locations throughout the country, with users including landowners, real estate agents and hikers. It has offices in 36 localities across Finland, from Mariehamn to Ivalo, employing 1,630 people.
A lasting relationship
Every four years, the NLS carries out an assessment of geomatics equipment, services and solutions to ensure optimum efficiency and reliability. This tender process last took place in 2015, with Topcon receivers outperforming all alternatives in field tests and satisfying all other requirements. This led Topcon to win the bid to supply 400 of its HiPer SR network GNSS receivers in 2016 and retain the contract for two years.
The receivers were used to carry out field-based operations connecting to and receiving real-time kinematic (RTK) data from the national network’s GNSS system. Field surveyors have also been using Topcon’s MAGNET software to facilitate seamless field-to-office workflow.
At the end of 2016, NLS tested Topcon’s new HiPer HR receiver and FC-5000 field controller, finding it was the best combination they had used, so the following year they ordered 206 of these kits – and another 171 for 2018.
