lasR - v0.3.0

lasR 0.3.0

• Change: processor() and reader() are deprecated and are replaced by exec() and reader_las(). This intends to provide a more consistent and natural way to separate the pipeline. i.e the stages and the global processing options i.e. the buffer, the chunking, the progress bar. For example the following now respects the LAScatalog processing options and this was not possible with the previous syntax.

  ctg = lidR::readLAScatalog()
  pipeline = reader_las() + rasterize(...)
  exec(pipeline, on = ctg)
  

• New: the processor is now able to process by chunk like lidR

  pipeline = reader_las() + rasterize(...)
  exec(pipeline, on = file, chunk = 500)
  

• New: stage delete_points() to remove some points in the pipeline.
• New: it is now possible to write the following:

  dtm = dtm()
  pipeline <- read + dtm + transform_with(dtm[[2]])
  

• New: it is not possible to omit the reader stage. It automatically adds a default reader

  pipeline = rasterize(...)
  exec(pipeline, on = ctg)
  

• New: triangulation is 4x faster and uses half the memory.
• Fix: summarize(), rasterize() and write_las() no longer process withheld points in streaming mode.
