<p>Hi Luigi<br>
</p>
<p>A PDAL processing toolbox will be nice to have. This is a great
addition to the QGIS project. Keep in mind that LAStools is
intergrated in the processing toolbox but it is not free. You can
make small project but for anything serious or professiona you
will need to pay for LAStools or else, you are using a limited
demo. This being said, LAStools is not that expensive, has a very
good email list where trouble shooting is done on the fly by the
developer. I would buy it. Las2dem (not open source), as an
example, will add black lines in the DEM if the data files are
past a certain size. LAStools does have open source tools (like
las2txt.exe) but las2dem is not one of them. This being said, I
work with the open source tools from PDAL and LAStools and use
GDAL Grid (available with QGIS) and Cloud Compare to generate the
DEMs. <br>
</p>
<p>If your company does not have a GIS, then the cost of the
learning curve between ArcGIS and QGIS will not be very
different. QGIS and variety of Open Source software like Cloud
Compare, GRASS, SAGA can do everything you want. Some is easier
with ArcGIS and some is easier with QGIS. Personally, I have
never purchased an ArcGIS license and don't see the advantage.</p>
<p>Keep in mind that doing this stuff will require that people in
the company learn about GIS and not just on how to run software if
you want to make a good professional job. Send me a personal email
if you want examples of this stuff. I am currently working on a
project in Peru and could probably share some screen shots. I am
in Montréal, Canada. I can also do training in French and
English. I also speak Spanish but it's a little rusty. I am
finishing a Ph.D. in a Remote sensing lab with extensive use of
LiDAR and DEMs.<br>

<p>P.S.<br>
</p>
<p>You will probably want to work with TauDEM, a qgis plugin for
hydrologic analysis. Look at

<div dir="ltr">Hi,
<div><br>
</div>
<div>All you listed is possible to process in qgis via all
possibilities offered by backend integrated in processing
(GRASS; SAGA, native qgis algs etc etc), btw about LIDAR
data in a week I'll push a new provider for qgis processing
toolbox that will allow the use of PDAL (<a
href="http://www.pdal.io" moz-do-not-send="true">http://www.pdal.io</a>)
in processing. This will allow you to create automatic
workflow to automatically process basin delineation from
lidar data. BTW right now you can already use LASTools
integrated in processing toolbox. las2dem command can
generate dem for basin delineation.</div>
<div><br>
</div>
<div>I strongly suggest to</div>
<div>1) avoid to spend for Arc licences and in opposite</div>
<div> A) invest in qgis upstream fixes via hiring core
developers or financing directly qgis project</div>
<div> B) customize your workflows hiring a power user</div>
<div> C) pay training to do all above in-house</div>
<div>2) invest contributing the new PDALtools in processing</div>
<div>3) invest contributing to PDAL</div>
<div><br>
</div>
<div>all above suggestion allow your company to have ALSO a
more direct control on your product respect depending on
external marketing decisions.</div>
