Problem lasnormalized LASlib

[THLAB35]

Hi,

I managed to create a dtm with no problem. On the other hand, when I want to create a dsm, I encounter a problem from the start and this error code appears:

cannot open file "chemin d'accès" for write
ERROR: cannot open laswriterlas with file name
LASlib internal error. See message above.
In addition: Warning message:
lasnormalize is deprecated. Use normalize_height instead. 

Thank you in advance for all the help you could give me.

[Jean-Romain]

Please provide a minimal reproducible example. Error without the code that generated it does not help.

[Jean-Romain]

First lasnormalize is deprecated since 17 months. See https://github.com/Jean-Romain/lidR/releases/tag/v3.0.0

In addition: Warning message:
lasnormalize is deprecated. Use normalize_height instead. 

But this does not explain the error. I need to see more.

I see

cannot open file "chemin d'accès" for write

What is chemin d'accès. Show me the files names.

head(las_cat_A2$filename)

Please copy paste what I wrote, not only the half

[Jean-Romain]

C:Travail/LiDAR/S21088_SNC_Jonquiere/las_out/norm_A2/norm_256000_5362500.las is not a valid path on Windows.

[Jean-Romain]

Is it possible that you show me the paths with head(las_cat_A2$filename) ?!

[Jean-Romain]

You have only one file ?

That look like an encoding issue. Please try

rlas::read.las(las_cat_A2$filename)

[Jean-Romain]

So it is a problem with lidR there is somewhere a badly encoded string. Try

cl = catalog_makechunks(las_cat_A2)
readLAS(cl[[1]])

[Jean-Romain]

I don't know what to say. Please try to make a reproducible example

opt_output_files(las_cat_A2) <- "C:/las_out/norm_A2/norm_{XLEFT}_{YBOTTOM}"
lasnorm_A2 <- lasnormalize(las_cat_A2, dtm_A2)

Is not nought. What did you do before that ? Show me summary of las_cat_A2 ? Try to make something reproducible.

Actually I'm lost in your issue because I asked you many time the same info before to get something, you gave me partial answers, then you changed your answers and so on.

[Jean-Romain]

Your file is absolutely unreadable. Code, outputs, errors, comments, everything is mixed-up without any coloring and frame. There are several calls to unrelated packages (e.g. tmap), The last thing I see is

In dir.create(dir, recursive = TRUE) :
  cannot create dir 'D:\lidar_out', reason 'Permission denied'

Which is an error on your side. If you do not have rights to write in D: do not write in D:.

Notice that you are showing me another new error never mentioned earlier. I'm sorry but I give up
