Let's try taking a couple steps back.<br>
<br>
Which method did you use to install the QGIS? Standalone or OSGeo4W or<br>
Source Compiled(which compiler)<br>
Can you post a link to a sample GML file for others to test?<br>
<br></blockquote><div><br>I used the download link from the <a href="http://qgis.org">qgis.org</a> website :)<br><a href="http://qgis.org/downloads/QGIS-OSGeo4W-1.6.0-14615-Setup-2.exe">http://qgis.org/downloads/QGIS-OSGeo4W-1.6.0-14615-Setup-2.exe</a><br>
... and that's the one that didn't open up.<br><br><a href="http://download.osgeo.org/qgis/win32/">http://download.osgeo.org/qgis/win32/</a><br><a href="http://download.osgeo.org/qgis/win32/QGIS-1.3.0-3-No-GrassSetup.exe">http://download.osgeo.org/qgis/win32/QGIS-1.3.0-3-No-GrassSetup.exe</a> installed just fine<br>

ogrinfo and ogr2ogr are tools to help test if the problem is with the<br>
gml file. QGIS at it's core uses the same libraries to open gml files<br>
and that's what makes it a good test.<br></blockquote><div><br>The .gml files are here<br><a href="http://ftp2.cits.rncan.gc.ca/pub/canvec/province_gml/nl/">http://ftp2.cits.rncan.gc.ca/pub/canvec/province_gml/nl/</a><br>
(all of these need to be turned to .shp files)<br><br>The program ogr2ogr.exe worked, using the simple instructions that <span class="gI"><span class="gD" style="color: rgb(121, 6, 25);">aperi2007 provided<br><br>title big_bad_ogr2ogr<br>
cd\<br>d:<br>cd\try-gdal<br>pause<br>ogr2ogr.exe -f "ESRI Shapefile" d:\try-gdal NL_LX.gml<br><br></span></span>it took some time to number crunch, but it did make a whole bunch of .shp files :) ... accept the projection is still off.<br>
So i need to add "EPSG : 4617" or some random 4 digit number that will work.<br><br>ogr2ogr.exe -f "ESRI Shapefile" -t_srs EPSG:4617 d:\try3-gdal NL_LX.gml<br><br>What i dont know is exactly which projection code to use or the prefix to use for it. <a href="http://www.gdal.org/ogr2ogr.html">http://www.gdal.org/ogr2ogr.html</a> assumes that the user already knows how to use the program :)<br>
... if i get this right then there is no need to mess with qgis :-)<br><br>cheers,<br>sam<br><br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
