That's the wrong direction.  Now I feel guilty. ;)

Re: [Qgis-user] PDAL to the rescue

[Drew French]

Thanks Luigi - I am a beginner with json pipelines and python scripts, as
well as PDAL, but am learning how useful this workflow is. When you switch
from clicking buttons to understanding the code you get a much better grasp
of what is happening behind the scenes, as well as your actual work needs.

I did create a json pipeline and used PDAL command "pipeline" in the
terminal. I know I should be using Conda but I still haven't understood the
need for Conda quite yet, if anybody can explain that a little more. Is it
okay to simply use the terminal or should I be using Conda?

I am also trying to learn Julia in order to use Circuitscape and that is a
whole nother ball of wax. There really are no beginner tutorials on a lot
of these more specialized applications  one is expected to understand quite
a bit of code before even attempting to use some of them.

Thanks,

Andrew

[QGIS-it-user] Creare segmenti da punti csv usando timestamp?

[Luca Moiana]

Ciao,

ho un GPS che registra un punto ogni secondo.
Scarico i punti e grazie al plugin PointsToPaths creo dei percorsi divisi per 
data.

Quello che vorrei fare è distinguere i diversi percorsi fatti nella stessa 
giornata.
Penso che la soluzione sia usare il timestamp e interrompere il percorso quando 
la differenza con il punto successivo è > 1 sec.


Avete suggerimenti o meglio, esiste già un plugin che fa questa cosa?


grazie

Re: [Qgis-user] PDAL to the rescue

[Luigi Pirelli]

completly agree with you. W PDAL :)

I strongly suggest to automize your processes. creating json pipelines and
consume them creating python/processing scripts using pyton interface to
PDAL (can be named pyPDAL?).

Is this your use case? tell us more or better prepare a UseCase story that
can be published in QGIS pages.

regards

Luigi Pirelli
