Hi Calle,<br>
As you have correctly noted, the .prj file tells QGIS how to
interpret th embeded "bunch of numbers" [ie: coordinates] in the
shapefile geometry.<br>
This means that you cannot simply edit the prj file - you actually
have to change the bunch of numbers inside the shapefile to be
latlong values that are in the correct place in Namibia.<br>
So:<br>
<blockquote>Simply open a "clean" QGIS, and note that the empty
viewport is in EPSG:4326 (bottom right corner of QGIS window.<br>
Drag and drop your shapefile into the Layers Panel (note the
bottom right CRS should change to your Shapefile CRS)<br>
right-click your shapefile name in the Layers Panel and choose
Save As<br>
In the pop-up window, check that "Format" is set to ESRI
Shapefile, Choose a Filename for your LatLong shapefile and change
CRS to EPSG:4326 - and click OK<br>
</blockquote>
Your saved shapefile will now have been reprojected to GCS on
WGS84.<br>
To be pedantic, close this QGIS and open a new QGIS, and drag/drop
your saved shapefile into it.<br>

HTH, (no, not the chlorine product)<br>

<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve received two shapefiles from Namibia –
originally from the National Statistics Agency, I think –
which has the following .prj file:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">PROJCS["New_Namibian",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],<o:p></o:p></p>
<p class="MsoNormal">PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",600000.0],PARAMETER["False_Northing",10000000.0],PARAMETER["Central_Meridian",17.0],PARAMETER["Scale_Factor",1.0],PARAMETER["Latitude_Of_Origin",0.0],UNIT["Meter",1.0]]<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When I open the file in QGIS and hover over
the maps, the coordinates shown are clearly projected
coordinates.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My problem is that I need the maps in EPSG
4326 (WGS-84, geographical coordinates) format, and I’ve been
unable to do the conversion – changing the value under
shapefile->Properties make the shapefile disappear.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So I’m doing something wrong – probably
something really dumb – but I don’t know WHAT….<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Anybody able to give me step-by-step
instructions on how to re-project “New Namibian” back to
standard EPSG 4326?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
