Hi,

I have data in a custom projection written into a postgis table from a
shapefile.

I have a copy of some docs describibing srid's but am still not sure how to
create an appropriate entry in tne spatial_ref_sys table that will allow me to
reproject (transform) the data to lat/long to allow spatial queries/joins with
my other lat/long datasets.

I have been told the supplied data coordinates are mercator northings &
eastings in metres, using wgs84 spheroid, with a central meridian of 100E and
latitude of true scale at 41S. There are no false northing/easting offsets.

Can someone suggest how this can be specified in the spatial_ref_sys table?


Thanks

  Brent Wood
