[mapserver-users] Preparing GeoTIFF files for use in Mapserver

[Robert Sanson]

Hi 
 
I am trying to use gdal_translate to convert some image files (PNGs and JPEGs) into GeoTIFFs for using in Mapserver. I am using the gdal_translate utility. The problem I am having is getting the proper Projection information embedded. I want to assign EPSG:2193 (NZGD2000 / New Zealand Transverse Mercator 2000).
 
I have .jgw / .pgw worldfiles and ESRI .prj files for my input files.
 
When I try:
 
gdal_translate -of GTiff -co "TILED=YES" -a_srs "EPSG:2193" infile.jpg outfile.tif
 
then examine outfile.tif with gdalinfo, it shows:
 
PROJCS["unnamed",
    GEOGCS[,
        DATUM["unknown",
            SPHEROID["unretrievable - using WGS84",6378137,298.257223563]],
        PRIMEM["Greenwich",0],
        UNIT["degree",0.0174532925199433]],
    UNIT["metre",1,
        AUTHORITY["EPSG","9001"]],
    AUTHORITY["EPSG","2193"]]
 
It doesn't seem to be finding the correct EPSG reference. I have GDAL_DATA environment variable specified, and have also included it in my path. I am using the gdal utilities that came with ms4w.
 
Many thanks,
 
Robert Sanson
