<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">I meant declaring user CRS (based on your PRJ file) and using the French grid file (both things in the same test, using gvSIG 1.9 or gvSIG 1.10).</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">Your successful test was using gvSIG 1.10 or gvSIG OADE 2010?</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">This is my experience with gvSIG OADE 2010 and transformations:</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">- Windows XP, EPSG transformation, ED50-WGS84: OK</font></div>

<td valign="top">Hello, Michel:<br><br>I believe gvSIG OADE 2010 is not performing any transformation at least on Windows Vista. Manual, EPSG, and grid-based transformations are all ignored. I think this is why you got a 50 m error in your test. Which operating system are you using?<br><br>Official gvSIG 1.10 does not have this problem, and I have been able to use grid-based transformation with your shapefiles successfully. You can try this on gvSIG 1.9 or gvSIG 1.10:<br><br>- close gvSIG if it's running.<br><br>- download <a href="http://www.killetsoft.de/zip/ntv2/france.zip" target="_blank">http://www.killetsoft.de/zip/ntv2/france.zip</a> to your PC and unzip it.<br><br>- rename the file FRANCE.GSB to ntf_to_r93.gsb (the extension must be .gsb in lower case) and copy it to the folder:<br><br>[GVSIG_FOLDER]\bin\gvSIG\extensiones\org.gvsig.crs\data<br><br>- check that the size of ntf_to_r93.gsb in that folder is about 271 KB.<br><br>- start gvSIG and do the test in the same way as before, but instead of choosing 'Manual transformation', choose 'Grid transformation', then in the combo box, you should be able to choose ntf_to_r93.gsb and then -very important- you have to change the radio button under the combo box. Choose the one to the right 'CRS of the view'.<br><br>In this way, I get a much smaller error. Some vertices differ by less than one cm, others differ by 1.5 cm, etc.<br><br>Out of curiosity:<br><br>Where do your shapefiles come from?<br>One of them is the original and the other was derived very accurately?<br>Or maybe both were derived from a third (original) shapefile?<br>How were they derived? I thought they could have been derived using the same .gsb file I have used, but I think a divergence of 1.5 cm cannot be caused by accidental roundings.<br><br>Regards,<br>Juan Lucas Domínguez Rubio<br><br><a href="http://gvsigmobileonopenmoko.wordpress.com/" target="_blank">http://gvsigmobileonopenmoko.wordpress.com</a><br><a href="http://tellusproject.blogspot.com/" target="_blank">http://tellusproject.blogspot.com</a><br><br>--- On <b>Fri, 7/16/10, Bouillot Michel <i><michel.bouillot@montreuil.fr></i></b> wrote:<br>

<div><font color="#000000" face="Times New Roman" size="3">Hello, Michel:</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">I think there's some confusion about the meaning of the EPSG codes. According to spatialref.org, the PRJ file for EPSG:27561 is this:</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3"><a href="http://spatialreference.org/ref/epsg/27561/prj/" target="_blank">http://spatialreference.org/ref/epsg/27561/prj/</a></font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">But that file is not like the one that comes with your shapefile.</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">gvSIG is probably using the definition found in the spatialref.org website, so that's why your shapefiles do not match if you select EPSG:27561 when adding that file to your view.</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">According to spatialref.org, the CRS that matches your PRJ file is 'NTF Lambert Zone 1 France 2SP' (code SR-ORG:6910):</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3"><a href="http://spatialreference.org/ref/sr-org/6910/prj/" target="_blank">http://spatialreference.org/ref/sr-org/6910/prj/</a></font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">So all you have to do is declare it as a user-defined CRS in gvSIG.</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">This has worked for me (I'll refer to your files as montreuil_2154.shp and montreuil_27561.shp):</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">- from the project manager, click 'New' to create a new view. Select it (without opening it) and click on 'Properties'</font></div>
<div><font color="#000000" face="Times New Roman" size="3">- clic on the [...] button to change the view's CRS</font></div>
<div><font color="#000000" face="Times New Roman" size="3">- choose 'Type: user CRS' and click on 'New'</font></div>
<div><font color="#000000" face="Times New Roman" size="3">- choose the 'From WKT' option and paste this paragraph in the text box:</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">PROJCS["unnamed",GEOGCS["unnamed ellipse",DATUM["unknown",SPHEROID["unnamed",6378249.2,293.4660200000053],TOWGS84[-168,-60,320,0,0,0,0]],PRIMEM["Greenwich",0],UNIT["degree",0.0174532925199433]],PROJECTION["Lambert_Conformal_Conic_2SP"],PARAMETER["standard_parallel_1",48.5985227778],PARAMETER["standard_parallel_2",50.3959116667],PARAMETER["latitude_of_origin",49.5],PARAMETER["central_meridian",2.3372291667],PARAMETER["false_easting",600000],PARAMETER["false_northing",200000],UNIT["Meter",1],AUTHORITY["EPSG","12345"]]</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">- click on 'Finalize' and 'Accept'. You'll see that gvSIG refers to the new CRS as 'USR:1' or similar.</font></div>
<div><font color="#000000" face="Times New Roman" size="3">- click 'Accept' again and open the view</font></div>
<div><font color="#000000" face="Times New Roman" size="3">- add the file montreuil_27561.shp without any additional option because we know it's the same CRS of the view.</font></div>
<div><font color="#000000" face="Times New Roman" size="3">- go to the 'Add file' option again, choose the file montreuil_2154.shp and before clicking on 'Accept', click on the button to indicate the CRS of the file that is being added. Search for EPSG:2154 (this one has no problem, you can use it) and select it, then you need to choose the 'Manual transformation' option in the transformation combo box. The seven parameters are:</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">168</font></div>
<div><font color="#000000" face="Times New Roman" size="3">60</font></div>

<div><font color="#000000" face="Times New Roman" size="3">0</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">- click 'Accept' on all the following dialogs, and both shapefiles should match. There is a small error of about 1.5 m, but I don't think that's a problem for you.</font></div>
<div> </div>
<div><font color="#000000" face="Times New Roman" size="3">Does this process work for you?</font></div>
<div><font color="#000000" face="Times New Roman" size="3"></font> </div>
<div><font color="#000000" face="Times New Roman" size="3">The CRS you have defined should be available from now on, but you will have to type the seven parameters each time from the 'Manual transformation' option.</font></div>
<div><font color="#000000" face="Times New Roman" size="3"></font> </div>
<div><font color="#000000" face="Times New Roman" size="3">Those seven parameters are valid if the view is in 'NTF Lambert Zone 1 France 2SP'. If the view is in EPSG:2154 and you add a shapefile in 'NTF Lambert Zone 1 France 2SP', you'll have to reverse the sign of the parameters.</font></div>
<div><font color="#000000" face="Times New Roman" size="3"></font> </div>
<div><font color="#000000" face="Times New Roman" size="3">If you don't want to deal with user CRS and parameters inside gvSIG, you can reproject your shapefiles before starting gvSIG. There is a nice free program that does that:</font></div>
<div><font color="#000000" face="Times New Roman" size="3"></font> </div>
<div><font color="#000000" face="Times New Roman" size="3"><a href="http://fwtools.maptools.org/" target="_blank">http://fwtools.maptools.org</a></font></div>
<div><font color="#000000" face="Times New Roman" size="3"></font> </div>
<div><font color="#000000" face="Times New Roman" size="3">The command would be something like:</font></div>
<div><font color="#000000" face="Times New Roman" size="3"></font> </div>
<div><font color="#000000" face="Times New Roman" size="3">ogr2ogr -f "ESRI Shapefile" -s_srs epsg:2154 -t_srs epsg:27561 new_file.shp old_file_2154.shp</font></div>
<div><font color="#000000" face="Times New Roman" size="3"></font> </div>
<div><font color="#000000" face="Times New Roman" size="3">(but again, we should check the meaning of EPSG:27561 in that case)</font></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>
