<div dir="ltr"><div dir="ltr">Hi Jo,</div><div dir="ltr"><br></div><div dir="ltr">There are quite a few algorithms implemented in PDAL to do data reduction and feature extraction -- it really depends on your needs and the details of your data.

<br>
I've been at a seminar focusing on machine learning applications for palaeontology, thinking of PDAL and not quite sure why. Various folks here have very high resolution laser or LED scans of very small objects and are interested in doing 3D model classification. <br>
<br>
Is there a moral equivalent of GDAL's Polygonize function in PDAL or a Douglas-Peucker like algorithm for point cloud simplification? Is anyone on this list looking at this sort of problem domain? Am I talking out my hat?<br>
<br>
Cheers,<br>
