<div><font color="#000000" face="Times New Roman" size="3">Hello, I think there's a misunderstood.</font></div>
<div> </div>
<div>gvSIG is able to do on-the-fly reprojection (this is what Michel needs, I think).</div>
<div> </div>
<div>But I'm afraid that, even if he follows the right steps to do it, the result will be wrong because (I think) gvSIG does not know the right parameters to perform that conversion (between EPSG:2154 and EPSG:27561).</div>
<div> </div>
<div>There have been problems with the French projections in the past, and I'm not sure if they were caused by a bug in gvSIG or in the libraries used by gvSIG (especially Proj4).</div>
<div> </div>
<div>Michel: can you please send to the list two little shapefiles (one in EPSG:2154 and the other in EPSG:27561) that should match but do not match in gvSIG? So we can also do some tests.</div>
<div> </div>
