lascheck: Inspect a LAS object

Description

Performs a deep inspection of a LAS or LAScatalog object and prints a report. For a LAS object it checks:

• if the point cloud is valid according to las specification

• if the header is valid according to las specification

• if the point cloud is in accordance with the header

• if the point cloud has duplicated points and degenerated ground points

• it the coordinate reference sytem is correctly recorded

• if some pre-processing, such as normalization or ground filtering, is already done.

For a LAScatalog object it checks:

• if the headers are consistent across files

• if the files are overlapping

• if some pre-processing, such as normalization, is already done.

For the pre-processing tests the function only makes an estimation and may not be correct.
