<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>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.</DIV>
<DIV> </DIV>
<DIV>i.e </DIV>
<DIV> </DIV>
<DIV>"ogr2ogr -f "Mapinfo File" temp PG:dbname=xxxx -t_srs EPSG:27200 table"</DIV>
<DIV> </DIV>
<DIV>instead of</DIV>
<DIV> </DIV>
<DIV>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</DIV>
<DIV> </DIV>
<DIV>Thanks</DIV>
