          Local Tie Surveys
         
        
         
        
         Local tie surveys facilitate the combination of two or more space-geodetic techniques 
           to better define the International Terrestrial Reference Frame (ITRF). They also provide 
           the connection of the reference point to the geodetic infrastructure. This page compiles 
           reports about local geodetic surveys made available by Network Stations.
         
        
         
          Warkworth.
         
         The site at Warkworth hosts an IVS Network Station (12-m
           and 30-m antennas) as well as a GNSS CORS site. Local surveys were conducted to
           connect the reference points of the two space-geodetic techniques. An
         
          overview
           of the surveys
         
         is given on the website of Land Information New Zealand. Reports
           on the 2012 and 2015 surveys can be accessed via the following links:
