Hi,<br>
<br>
the referencing module of the geotoolkit library handle towgs84
parameters (<a class="moz-txt-link-freetext" href="http://www.geotoolkit.org/">http://www.geotoolkit.org/</a>). it also have a xml parser
for osm, a client for api 0.6 and osm tms servers in
geotoolkit-pending. <br>
<br>
you can find several demo modules in the code. Ask if you have
troubles ;)<br>

Following on from my post about the Austrian grid system, I'm
having a bit of trouble using the Java Proj.4 library as it
ignores datum shifts which means the projected values are about
100m out. For OSGB it's not a problem as I have another library
which does the job but for anywhere else in the world which
doesn't use WGS84 it could be tricky.<br>
<br>
So just out of interest, has anyone written Java code to do
datum shifting based on the "towgs84" parameters in Proj.4
definition files? Obviously I could look up how to do this
myself but time before SOTM is a little tight and if some
open-source code exists already I may as well use that :-)<br>
<br>
Thanks,<br>
