<p>Hello,</p>
<p>Is there a way to classify a point cloud based on a rater or
vectorial file using PDAL?</p>
<p>When flying a drone it has 2 sensors (lidar and multispectral).
With the second one we can calculate several vegetation indices
that help us to differentiate soil from vegetation in a raster.<br>
<br>
Our idea is to classify the points that correspond to the ground
in order to create a dtm. Then we can subtract the dsm created
from the point cloud and the dtm to obtain the phytovolume.<br>
<br>
The problem is that it is not clear to me if it is possible to
classify a point cloud with PDAL using a raster.<br>
<br>
A colleague of the list has told me that maybe it can be done with
<i>filters.colorization </i>but I don't know exactly if it is
like that or how to indicate to the tool that the raster
information has to go to the classification and not to the color
bands.<br>
<br>
Could someone give me a hand or a hint on how to follow?<br>
<br>
<br>
Best regards and thanks.<br>
