[Gdal-dev] using nad grid within ogr2ogr

[Jeremy Palmer]

Hi,
 
Is is possible to update the projection definitions that ogr2ogr uses
to include the use of a custom nad grid? I know you can specific the
proj4 def on the command line, but it would be useful to be able to
update the gdal data defintions files so I can just use the EPSG srid on
the command line.
 
i.e 
 
"ogr2ogr -f "Mapinfo File" temp PG:dbname=xxxx -t_srs EPSG:27200
table"
 
instead of
 
ogr2ogr -f "Mapinfo File" temp PG:dbname=xxxx -t_srs "+proj=nzmg
+lat_0=-41 +lon_0=173 +x_0=2510000 +y_0=6023150 +ellps=intl
+datum=nzgd49 +units=m +no_defs  <> +nadgrids=nzgd2kgrid0005.gsb" table
 
Thanks
Jeremy
