1. NOTE THAT TRIG_PNT OBJECTS WERE NOT DIGITISED FROM THE MAP SOURCE ON WHICH THEY APPEAR - THEY ARE OBTAINED FROM THE GEODETIC STATIONS DATABASE. 2. LINZ Topographic Map series are not intended to be a complete record of survey control, in most cases only trigs of order 1 to 4 are shown, trigs of order 5 are only shown if beaconed. Clusters of trigs are not shown - only the trig with the highest order within the cluster is shown.
