Netherland POsitioning Service

This data layer contains the positions of GNSS (Global Navigation Satellite System) stations of the systems AGRS and NETPOS stationed at RWS locations. Both systems are owned and managed by the Land Registry and RWS (CIV). The AGRS (Active GNSS Reference System) consists of a number of well-founded GNSS setups, the data of which is continuously collected (every second) and stored (every 30 seconds). These stations are mainly positioned near underground NAP brands, level scale setups and gravity measuring points. Users of the data of this system are, in addition to Het Kadaster and RWS, among others the Dutch and International knowledge institutes, and a number of companies, which carry out work for the Land Registry or RWS. The NETPOS (Netherland POsitioning Service) system is a GNSS RTK network system, which provides real-time corrections to GNSS positions. NETPOS reference stations are located throughout the Netherlands, mainly on buildings of Het Kadaster and RWS. Users of the NETPOS corrections are, in addition to Het Kadaster and RWS, a number of companies that carry out work for Het Kadaster and RWS.
