That's unfortunate. Good to know its repeatable. At least the
problem has been isolated and we know what's required to get it
fixed (or so I think).<br>
<br>
Time to find some professional help. I'll keep you informed.<br>

I am using Linux and from a previous email I think Ken is as
well. Yes,
it is working on my Linux system.<br>
<br>
I tried installing QGIS onto a Windows 7 system using both the
Standalone and OsGeo installers. In both cases I couldn't get
it to
work correctly. The standalone installer version placed AGD66
and GDA94
versions of my test point 11m apart when it should be more
like 200m.
The OsGeo version just refused to display the AGD66 point.<br>
<br>
I am not sure where to go with it on Windows. I haven't used
it for a
long time. Maybe someone more familiar with the Windows setup
can help.<br>
<br>
Cheers,<br>

Sorry to disappear like that. Got called into the dessert for a
few
days.<br>
<br>
I tried loading these new files up but can't get them to work.
All
three projections are now plotting in exactly the same place. <br>
<br>
Ran a search on the QGIS directory and replaced the AGD84 /
AGD66 gsb
files with the new ones. Also replaced the srs.db file.<br>
<br>
I'm assuming you both got this to work. Am I missing a step?<br>

The only thing we know for certain is that we are all
out of our
depths! Regardless, I think we are on the way to solving
this.<br>
<br>
Please find a new srs.db here <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://dl.dropbox.com/u/9546967/srs.db">http://dl.dropbox.com/u/9546967/srs.db</a>.
The new file incorporates both towgs84 parameters and a
reference to
the distortion files. The distortion file values appear
to take
precedence, but I have included the towgs84 parameters
as it looks like
the AGD84 distortion files do not cover the states and
territories that
did not adopt AGD84. Note that I have changed the AGD66
towgs84
parameters to national ones (previously ACT) according
to this document
(page 31) <a moz-do-not-send="true"

href="http://www.icsm.gov.au/gda/gdatm/gdav2.3.pdf">http://www.icsm.gov.au/gda/gdatm/gdav2.3.pdf</a>.<br>
<br>
To use the distortion files you need to place these
files <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://dl.dropbox.com/u/9546967/agd66.gsb">http://dl.dropbox.com/u/9546967/agd66.gsb</a>

in your Proj data directory (/usr/share/proj on Linux).
It is the
directory containing the 'epsg' and 'proj_def.dat'
files. Make sure
that this is the directory your Proj installation is
actually using by
checking the contents of the PROJ_LIB environment
variable (echo
$PROJ_LIB). It may not be set, which is OK. It took me
about 4 hours to
figure out I had set it to an old development directory
several years
ago!<br>
<br>
Note that I did try it without the +wktext parameter. It
works in Proj
(using cs2cs), but QGIS needs it.<br>
<br>
Let me know how it goes on your test points.<br>
<br>

<pre wrap="">Roland,
I incorporated your srs.db but the translation falls about 30m short (in
Melbourne) and about the same distance out at a control point in southern
Tasmania.
I see you use the National parameters that '... have an estimated accuracy
of about 1 metre.' and are most accurate around Canberra (surprise).
Geoscience recommend use of their distortion tables (xxx.gsb) for more
accurate work Australia-wide.
Can you incorporate the parameter reference to the distortion tables in the
srs.db? I, like Brett, am out of my depth here.
Regards
Ken
