[GRASS-web] importing multiples las files in grass gis (windows)

Hello dear grass
currently working with a project, where I need to build a DEM with a 2x2 meters
resolution. I have around 800 las files
with 0.7 and 2 points/sqm, which I
already converted to text format using the las2txt command as explained at
So, I intend to import all 800 .txt files into
GRASS GIS at once, if possible, in order to create my DEM from the entire area
time I try to import even one txt file in Grass Gis, by using the r.in.ixyz , I get the well- known allocation memory message (ERROR:
G_calloc: unable to allocate…. )
wrapping all together what I want to
1) To import all 800 files at once, instead
of importing one by one. I know it is possible in linux, but I have not figured
it out how to do it in the cmd (dos) windows.
Technical settings of my work environment:
Grass GIS 6.4 running on windows 7, installed using
the osGeo4W installer, fully operative.
The las data is over 750 GB. Lasdata was pre-processedusing lastools. Only class 2 (bare ground) was kept.
I hope someone can drop some lines about how to
do this in a windows environment. So, far I only found linux examples,
which uses eval, flags and pipes. All
this is not applicable in cmd.
Thanks in advance.
