[pdal] Make a boundary polygon closer to the point cloud

[Ulises Ibarra]

Hello.
I have a question: What do I have to do to make the boundary polygon closer
to the point cloud?

I would like to obtain a boundary from a cloud point. When I do the
following instruction, the resulting polygon is very loose, with too much
air between the points and the boundary.

> pdal tindex create --tindex
..\GEOJSON\cloud513663ed34e703b5_boudary_prueba.sqlite --filespec
.\cloud513663ed34e703b5.las -f SQLite

The result look like this, where the red polygon is the resulting polygon
by tindex and the yellow is the polygon resulting by the command
lasboundary from lastools: https://postimg.cc/RNHGsDWH

I would like it to look like the example image:

What do I have to do to make the boundary polygon closer to the point cloud?

This is the image of the point cloud: https://postimg.cc/fVQC6fdg

Greetings.
