[GRASS-user] v.in.ascii error: G_realloc

GRASS GRASS user

Hi,
thanks Markus for your help. v.in.ascii is working fine now.
But now I have problems with the created vector file. I think because of the
missing topology.
If I want to use the created vector file for example with v.patch I get the
error:

Cannot open old vector dtm1107_32@Solothurn on level 2

The same error if I use g.region vect=dtm1107_32

Another example: If I use v.surf.rst I get the error:

Vector is not 3D

Any suggestions how I can solve the problem?

Thanks

Michael

Hi Michael,

GRASS 6.1 can (probably) deal with such a number of points, but
you have to add the '-b' flag to not build the topology. See

http://grass.itc.it/grass61/manuals/html61_user/v.in.ascii.html

Cheers

Markus

Hi everybody
I wanted to import a large ASCII File in Grass 6.0.2 (about 300MB and

about

11.000.000 Points).

First everything was going fine but after some time i got the mistake:

ERROR: G_realloc: out of memory

What's going wrong?
Is it not possible to import such large files in Grass or is there a

maximum

size untill which v.in.ascii is working fine?

Thanks for your help

Michael

Only a couple of commands work without topology (to allow
working with large number of points). Would be good if
someone documents that in the Wiki.

Another example: If I use v.surf.rst I get the error:

Maybe you forgot the -z setting in v.in.ascii to import as 3D?
