[pdal] PDAL Vagrant/VirtualBox Install Failed at points2grid

[Robert Dzur]

Thanks Howard,

It does seem to install and allow me to do some things now; however, it also seems to be confused about the point returns for some reason.  So when I ran the following command:

>In short, everything loaded up just fine into pgpointcloud and you should be able to do stuff with it >now. `pdal pipeline readpgpointcloud.xml` should net you an LAS file now.

$ pdal pipeline readpgpointcloud.xml
I received the following error message:

/home/vagrant/pointcloud/st-helens-small-out.las: Found invalid value of '0' for point's number of returns.

Similarly I tested the ProgressiveMorphologicalFilterAdvancedExample against the st-helens las file again with some similar point return confusion it appears.

vagrant at pdal-vagrant:~/pointcloud$ pdal pipeline -i filter.xml

Caught PDAL exception: Unable to fetch data and convert as requested: ScanAngleRank:float(2107.93) -> signed char
 
I also tried to apply the same xml on another las file with similar results.

Thanks again for your input.
