I need one of your file. The problem is likely related to the format 1.4 maybe with the pdrf 8.
Reproduced with
library(lasR)
f <- system.file("extdata", "las14_prf6.laz", package="rlas")
pipeline <- reader(f) + dtm()
exec(pipeline)
I fixed my issue, which was related to the fact that there was 0 ground point. Maybe your issue is different. In my case the error is now
Erreur : in 'triangulate' while processing the point cloud: impossible to construct a Delaunay triangulation with 0 points
By the way the correct syntax is now (from 0.3.0)
pipeline <- reader_las() + dtm()
exec(pipeline, on = f)
reader_las()
can be conveniently omitted. Do not forget to read the changelog. lasR
is still maturing, the API is not definitive and may change.
thanks, fixed it. Forgot that the files were unclassified, with prior ground classification it works.

You might want to change this under e.g. https://r-lidar.github.io/lasR/reference/chm.html#ref-examples where its written as
f <- system.file("extdata", "Topography.las", package="lasR")
pipeline <- reader(f) + chm()
Thank you for reporting. I updated the doc
I try to run a simple pipeline, but R crashes (" R encountered a fatal error") quickly after execution start. This does not happen for the example file (
f <- system.file("extdata", "Topography.las", package="lasR")
) but for any of my tested files.So it seems that something with my file is the problem. However, with lidR I can read and plot the file.
Any idea what might cause this problem?
