WGS84 gps point in postgis

[Stéphane RIFF]

Hello,

I want to store WGS84 gps points in a postgis table:
       What is the format of WGS84 point in postgis ???
             For now i have something like this:
                   SRID=4326;POINT(DDMM.SSSS DDMM.SSSS)   ----> is that
ok ???

Next i want to show those gps points on raster map in other projection:
epsg:27582 (lambert II etendu)

Does somebody already do something like that...

All advices are wellcome

Thanks
