Just sth I noticed:

You cite the srtext definition in the spatial_ref_sys table:

> PROJCS["Portuguese_National_Grid",GEOGCS["GCS_Lisbon_Lisbon",DATUM["D_Lisbon",SPHEROID["International_1924",6378388,297]],PRIMEM["Lisbon",-9.131906111111112],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",200000],PARAMETER["False_Northing",300000],PARAMETER["Central_Meridian",1],PARAMETER["Scale_Factor",1],PARAMETER["Latitude_Of_Origin",39.66666666666666],UNIT["Meter",1]] 

However, when I looked at the definition found in 
http://gdal.velocet.ca/cgi-bin/csv2html/TABLE=p_meridian/CODE=8902/, the 
value for the prime meridian is -9.0754862. Which one is right? I don't 
have the EPSG data here to check it out (I have no application to read 
an Access DB... What idea is this to publish EPSG data in Access format?)

Bye, Luís
