[OSGeo Africa] How to convert "New Namibia" projection to EPSG 4326 in QGIS

Hi Calle,

The New Namibia CRS parameters are just fine. You need to re-projects the
files to your desired CRS.

I think the best way to go about that in QGIS, is to right click on the
layer name and SAVE AS to create a new file. Ensure that CRS of the new
file that you are creating, is changed to EPSG 4326 before saving.

I hope that helps.

Hi,



I’ve received two shapefiles from Namibia – originally from the National
Statistics Agency, I think – which has the following .prj file:



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]],

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]]



When I open the file in QGIS and hover over the maps, the coordinates shown
are clearly projected coordinates.



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.



So I’m doing something wrong – probably something really dumb – but I don’t
know WHAT….



Anybody able to give me step-by-step instructions on how to re-project “New
Namibian” back to standard EPSG 4326?
