WARNINGS
-
The default datum for horizontal coordinates available from SurCoM is
GDA2020, however coordinates for any mark in the system may also be
expressed in terms of other datums including GDA94 and AGD66. It is
the responsibility of users to ensure that the correct datum is
selected. The Government of Tasmania will not be responsible for any
loss caused by incorrect selection or interpretation of survey datums.
-
The identity and stability of a Survey Control Mark must be verified in
accordance with established survey best practice, before placing any
reliance on the coordinates or height of a mark. The Government of
Tasmania will not be responsible for any loss that might result from the
erroneous identification or instability of any Survey Control Mark.
-
Whilst every effort is made to validate the accuracy and integrity of
data contained in SurCoM, it is derived from a variety of sources, some
of which are outside the control of the Office of the Surveyor General.
The Government of Tasmania will not be responsible for any loss that
might be attributable to the presence in SurCoM of erroneous or
inaccurate information.
These three warnings should be read in conjunction with the
