comment How to convert LAS file to ASCII for DSM in SAGA GIS?
I don't see how this is a duplicate if someone is following a procedure specifically in saga.

comment Automating non-trivial workflow in SAGA-GIS
I just want to add: it is also possible to do this without python. In order to keep datasets in memory between several processing steps have a look at the saga_cmd --batch option. you can create file which specifies which modules to run. the syntax is very similar to usual batchfiles, and the files are kept in memory.

comment Fast and robust open source portable script or tool for interpolation - triangulation or similar
I should add that triangulation would actually be a bad idea if you want to have smooth contour lines (they will have sharp edges all over if you have little data). I think that indeed GDAL is probably the best option (I was not aware of gdal_fillnodata). As a tip, you could consider working with in memory rasters in gdal so you don't have to write/read to disk all the time.

Check the license carefully: triangle is NOT open source, it is only free for non commercial usage

What version are you using? What command are you running. In principle the gid column is not imported.
