Description

When exporting (Save As) layer data from QGIS master to Shapefile, the associated .prj file has incorrect projection WKT.

Info for projection:

Here is the WKT in the .prj file from an export of a layer with source projection srid=27200 from QGIS master (code fecb0de):

PROJCS["New_Zealand_Map_Grid",GEOGCS["GCS_International 1909 (Hayford)",DATUM["D_unknown",SPHEROID["intl",6378388,297]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["New_Zealand_Map_Grid"],PARAMETER["latitude_of_origin",-41],PARAMETER["Longitude_Of_Origin",173],PARAMETER["false_easting",2510000],PARAMETER["false_northing",6023150],UNIT["Meter",1]]

This should be something more like:

PROJCS["NZGD49 / New Zealand Map Grid",GEOGCS["NZGD49",DATUM["D_New_Zealand_1949",SPHEROID["International_1924",6378388,297]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["New_Zealand_Map_Grid"],PARAMETER["latitude_of_origin",-41],PARAMETER["central_meridian",173],PARAMETER["false_easting",2510000],PARAMETER["false_northing",6023150],UNIT["Meter",1]]

(see also "select srtext from spatial_ref_sys where srid=27200;" from PostGIS)

History

#1 Updated by Giovanni Manghi almost 8 years ago

  • Target version set to Version 1.7.4

#2 Updated by Paolo Cavallini over 7 years ago

Current Version of Qgis Master writes the following .prj file:

PROJCS["NZGD49_New_Zealand_Map_Grid",GEOGCS["GCS_New_Zealand_1949",DATUM["D_New_Zealand_1949",SPHEROID["International_1924",6378388,297]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["New_Zealand_Map_Grid"],PARAMETER["latitude_of_origin",-41],PARAMETER["Longitude_Of_Origin",173],PARAMETER["false_easting",2510000],PARAMETER["false_northing",6023150],UNIT["Meter",1]]

so I assume that it is already fixed in current GDAL 1.9.2
