How to extract mid and low vegetation

[Miguel Carrero]

Dear all,

I want to separately extract mid and low vegetation values from a .las file (classes 3 and 4 of ASPRS), to create a Digital Height Model with low and mid vegetation respectively. Is it possible to do it in LASTools?

I did it with high vegetation values isolating the first return, and bare-earth, but did not find the way to do it with other point classes.

Thanks for the attention,

Miguel.

Dear Miguel,

yes it is possible by using the command:

-keep_class 3 or -keep_class 4

Cheers,

Tobias
