Support EPT point cloud as input?

[joaori]

Hi,

Can EPT point clouds be used as input? The documentation page mentions that all PDAL-readable formats should be supported but looking at the code seems that files with json extension have a different parsing flow.

I've tried using a previously generated EPT scans as input for a new one without success (see below). Is there any way to do it using the current version of entwine?

#
# Generate an EPT point cloud

$ entwine build -i data/autzen.laz -o autzen-ept

@joaori Hi there. Seems you're not the only one to have encountered this. Did you find a resolution yourself or did you bypass it? I'm considering an "aws sync" to my EC2, followed by a ec2-local-->s3 ept build.
