              KOSG LOCAL TIE
*************************************************************

Recently a re-survey of the KOSG local tie, from the SLR 339334-23
(CDP 8833) to the stationary GPS survey marker 339334-25 (KOSG-25)
has been carried out and resulted in a confirmation of the current
values:
         dx = -12.461 m.
         dy = -37.503 m.
         dz =  23.024 m.
The height from the bottom of the chokerings to the staionary GPS
survey marker 339334-25 is
                0.105 m.
With kind regards, Danny van Loon.
