[GRASS-user] help v.lidar.mcc

Tue Jan 10 20:21:24 PST 2017

Hi Rafaela,

this is too big for testing, please make it smaller. You will at least
see if the problem is related to the size of the dataset. Also, as
Moritz suggested you, please run the command:

v.outlier --o ew_step=0.5 outlier=outlier filter=positive lambda=2.0
input=mylasinput threshold=0.4 output=output ns_step=0.5

because this is the command that actually failed and it should report
some errors.

Thank you,

Anna
