[GRASSLIST:249] FlightGear & GRASS

GRASS GRASS user
1

I plan to use GRASS and FlightGear (the flight simulator)
side-by-side, to fly over my data. Anyone tried this? Any suggestions?

FlightGear will write current position in Garmin and NMEA formats (GPS)
both to a file and to a socket. If I can read the socket with GRASS, I
could display current position+data on GRASS iin near-real-time. HOw can
a read a unix(linux) socket?

TIA.

Note that there is already an application that does this, using the
terrain data Flightgear has, namely Atlas (IIRC you can find it at
http://atlas.sourceforge.net).

gpsdrive can also do similar things, but is targetted more at driving.

FlightGear will write current position in Garmin and NMEA formats (GPS)
both to a file and to a socket. If I can read the socket with GRASS, I
could display current position+data on GRASS iin near-real-time. HOw can
a read a unix(linux) socket?

Using bash(1), or perl, or c etc.

BTW, I still think some better gps integation in grass would be nice,
but it's not necessary for what you want (I think).
