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
