	EPSG Tables
	===========

The .csv files in this directory are an extract of tables from the EPSG
projection database in CSV (comma separated value) format.  These same
files come with the source distribution in the libgeotiff/csv directory.
Information and source to extract these tables from the EPSG database
can be found in the source distribution libgeotiff/csv/odbc2csv directory.

Detailed information on the EPSG database can be found at:

 geod_datum:	geodetic datum data. 
 gdatum_alias:	geodetic datum alias data. 
 geod_trf:	geodetic transformation data. 
 horiz_cs:	geographic and projected coordinate system data (GCS/PCS codes)
 p_meridian:	prime meridian data. 
 trf_method:	transformation method and parameter data. 
 trf_nonpolynomial: projection and 3- or 7-parameter geodetic
                    transformation parameter values. 
 trf_path:	geodetic transformation path data. 
 uom_angle:	angle unit data.
