Dear all
I am a beginner user of grass gis.
I want to import a text file that included latitude, longitude,ID number and
recordig time, into grass as line data.
The format style is as follows:
id,x,y,time
1,857.8629761,-785.6849976,1
1,987.9949951,-682.4140015,2
1,964.4849854,-710.6849976,3

Dear Yasou
You can import any geometric element using v.in.ascii. Use
*format*=///standard/
and include in your a header with primitive code L (that is line).

If you search in the mailing list archives you'll find a script
I wrote for someone some months ago to do this. (that was for
animal tracks IIRC). Input format is always different, so it's
hard, but possible, to come up with an automatic solution.
as mentioned by others, the typical solution is
