Hi guys,

I noticed that some definitions for the EPSG codes in the epsg file is not
so clear, which means there are no parameters for the epsg codes, for
example:

# ETRS89 / UTM zone 32N
<25832> +proj=utm +zone=32 +ellps=GRS80 +units=m +no_defs  <>

the EPSG code for this one is 25832, but there are no other parameters any
more, such as longitude, latitude, central meridian, false northing, false
easting.....

and also this one:

# NAD83(HARN)
<4152> +proj=longlat +ellps=GRS80 +no_defs  <>


if the epsg code is defined like this, does it mean that the the EPSG code
is not valid for use or is not defined?

a little bit confused.

kind regards

zhonghai
