[pdal] Change vertical datum

[Ulises Ibarra]

 Hello everyone:

I'm not sure that the topics that I expose correspond to the topics that
are covered in this list, if not, I wish you could tell me where to go.  Maybe
on the PROJ list?

When I do a vertical datum shift of a point cloud, using the following
pipeline:

[
"input.las",
{
"type":"filters.reprojection",
"in_srs":"EPSG:32614",
"out_srs":"+init=epsg:32614 +geoidgrids=C:/nubes/geoides/GGM10_GEO.gtx"
},
{
"type":"writers.las",
"filename":"output_with_Vertical_Datum_GGM2010.las"
}
]

Questions:

1.- After running the command I get an alert:

" Warning 1: +init=epsg:XXXX syntax is deprecated. It might return a CRS
with a non-EPSG compliant axis order. "

Could you tell me what I'm doing wrong at this point?

2.- What argument would I have to use to see in the metadata something like
"Vertical Datum": "GGM10" or "Mexican Gravimetric Geoid 2010"? Of course,
in case the datum change has been made.

Best regards
