[GRASS-user] v.in.ascii don't work

[Michael Barton]

Emmanuel,

Here are some ideas

Is the region correct? That is, do these coordinates occur in your region
(check extents and resolution using g.region -gp or directly from the menu)?

Are the end of line/carriage return characters correct? You are on a Linux
system which ought to produce the correct ones, but it's worth checking.

Try a different field separator. Try a comma.

Change your column  names. Using "nul" and/or "val" could be problematic
