Subject: Re: r.in.ascii file sizes
Alynne,
Use the unix tools head, tail, and cat.
Suppose your file is called old.img. First use head to get the first six
lines to a new file:
head -6 old.img > new.img
So it looks like your old header:
north: 2318
south: 0
east: 1837
west: 0
rows: 2319
cols: 1838
Then edit the file with vi.
Next use cat to append old.img to new.img except the first 6 lines using
tail +6:
cat old.img | tail +6 >> new.img
Try it out on smaller files first to get the hang of it (no gaurantees,
I have not tried this in a while, seems like I used either
-5 or +5 because one of them starts counting at zero).

Hello,
Does anyone know a way around editing the header of ascii files (to be
imported
into grass using r.in.ascii) that are over 1 gig? VI does not work and
I'm wondering
if someone knows of alternative text editors that could be used....thanks, alynne.
