Inconsistency with the first value for position in pointcloud schema

[mhabets]

In https://raw.githubusercontent.com/PDAL/PDAL/0.9.8/schemas/LAS.xsd (referenced by http://pointcloud.org/schemas/PC/1.1), it is stated that the position tag is "the dimension's position in the block of point data (counting from 0)".

When I put 0 in my point cloud schema for the position of my first dimension, the insertion into pointcloud_formats fails. I get this first message which makes no sense to me:

WARNING:  schema dimension states position "0", but number of XML dimensions is "17"

directly followed by:

ERROR:  new row for relation "pointcloud_formats" violates check constraint "pointcloud_formats_schema_check"

Hey @mhabets,
it seems the doc is misleading,
I always started dim by the dim 1.
Can you confirm starting by 1 works for you, so I can update the doc and close the ticket?
Cheers,

Hi @Remi-C,
Yes it works fine with 1 as the first position.
At least the warning message should be clearer, shouldn't it?
See you ;-)
