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 2,1689.578979,-1070.564941,4 2,1654.074951,-1061.333008,5 2,1618.218018,-1040.505981,6 3,2335.930908,-1180.246948,7 3,2336.694092,-1197.869019,8 3,2336.658936,-1218.124023,9 4,2512.673096,-1689.875977,10 4,2494.010986,-1710.625977,11 5,1826.724976,-1731.743042,12 5,1808.57605,-1726.490967,13 5,1793.598999,-1723.034058,14 ..... ..... ..... ..... Firstly I intended to use 'v in ascii' command. However, this command imports a text data into points, I think. I want to import this text file into grass as line data according to the ID number. May this question be solved in grass? If it is so, please teach a solution....
