[Proj] Re: wgs point (lat-lon 'NMEA' to N-E 'metric')

[Massimo Di Stefano]

hi using a string like :

var="4051.1749|01415.5317"; echo "${var:0:2} ${var:2:2} ${var:5:2}.$ 
{var:7:2} ${var:10:3} ${var:13:2} ${var:16:2}.${var:18:2}"

i've reformatted the NMEA output to :

40 51 17.49 014 15 53.17


what is the right way
  to translate this coords
into a wgs "metric"  coordinate
... i'm using a grass location "wgs"

projection: 1 (UTM)
zone:       33
datum:      wgs84
ellipsoid:  wgs84


thanks for any suggestion,

Massimo
