<p>Hello,</p>
<p>Just wanted to point out that I did some updates on the wiki
while working on the data transformation :</p>
<p>* minor about fields (added some fixme, added a few fields)</p>
<p>* about geodesic system used : we finally chose not to transform
to wgs84 because the local system has a topographic accuracy, and
is close to wgs84 (OSM users won't see a difference : 30-50 cm
with standard qgis tranformation, or 1.5m taking into account
epoch). We are on the Pacific and the tectonic plate is moving of
7cm a year. So we chose to use the local system wich is fixed on
time and ensure to keep orginal accuracy which is high and great
value. Users won't create position error with inverse
transformation. We have discussed the issue on french mailing list
(discussion is linked on the wiki page of the import plan).</p>
<p>Have a great week end,</p>
<p>Violaine<br>

<p>Hello, <br>
</p>
<p>The SAU (similar to national geographic institute, in French
Polynesia) has requested my support to import some of their data
into OSM. We have the licence agreement ok.<br>
</p>
<p>We plan to start a first pilot with the commune of Arue, in
order to test the quality of our import process and improve it
if needed.<br>
</p>
<p>We would be very happy if you could bring your constructive
inputs about this, please have a look at wiki page dedicated for
that, you will find the data transformation scheme we used.</p>
<p>The details are available on the wiki here (<a

and you can also check the Data transformation model here

)</p>
<p>We are looking forward for feedbacks from you before we proceed
(from october). Please let us know if there are any comments,
questions or concerns.</p>
<p>Sincerely,</p>
<p>Violaine, and SAU team<br>
