tlsNormalize #15

Closed stefanoch90 closed 4 years ago

stefanoch90 commented 4 years ago

Hi, i have a problema con il command "tlsNormalize". I import the .LAS file from CLoudcompare after to apply the CSF plugin. The cloud import in R is only DSM. When i launch the tlsNormalize command, the score is " no ground points found, performing ground segmentation". How can i resolve this problem?

stefanoch90 commented 4 years ago

I have solved my question, the problem is the type file selected in cloudCompare. It is necessary save file in LAS 1.3 or 1.4 .

In case you didn't know, the lidR package has an implementation of CSF in lidR::classify_ground(). This will allow you to keep your workflow entirely within R..

Can CSF of lidR supports the point cloud any milion points?

Jean-Romain commented 4 years ago

The CSF of lidR relies on the same source code that the one of cloud compare i.e. the source code of the authors themselves.
