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:
