Hi,
Probably something for the LAStools?

Hi everyone,
for the purpose of speeding up a complex interpolation (written in
single core Fortran-code) we would want to split a cloud of points
(ca. 3 million irregular points) into X number of parts (eg 20 parts
of more or less 150 000 points). Does anyone know of some
QGIS-extension that could do this kind of a job?
I was looking at a Saga-gis module ("Shapes - Tools > Split Shapes
Layer Randomly") in the SEXTANTE toolbox. This is perfect if you want
to split shapes into two parts with varying proportions between the
two parts. I can perform this sequentially to arrive at the desired
number of parts, but is very time consuming if you want to compare
the
impact on the system of splitting everything in eg 20 parts versus 15
or 12 or..
Preferably, a solution should be executable from the command-line.
Cheers,
Olav
