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
