lascheck

An object of class <a rd-options="lidR:LAS-class" href="/link/LAS?package=lidR&version=2.0.2&to=lidR%3ALAS-class" data-mini-rdoc="lidR:LAS-class::LAS">LAS</a> or <a rd-options="lidR:LAScatalog-class" href="/link/LAScatalog?package=lidR&version=2.0.2&to=lidR%3ALAScatalog-class" data-mini-rdoc="lidR:LAScatalog-class::LAScatalog">LAScatalog</a>.

Performs a deep inspection of a LAS or LAScatalog object and prints a report.
For a LAS object it checks:<ul>
<li>if the point cloud is valid according to las specification</li>
<li>if the header is valid according to las specification</li>
<li>if the point cloud is in accordance with the header</li>
<li>if the point cloud has duplicated points and degenerated ground points</li>
<li>it the coordinate reference sytem is correctly recorded</li>
<li>if some pre-processing, such as normalization or ground filtering, is already done.</li>
</ul>For a LAScatalog object it checks:<ul>
<li>if the headers are consistent across files</li>
<li>if the files are overlapping</li>
<li>if some pre-processing, such as normalization, is already done.</li>
</ul>For the pre-processing tests the function only makes an estimation and may not be correct.

Airborne LiDAR (Light Detection and Ranging) interface for data
manipulation and visualization. Read/write 'las' and 'laz' files, computation
of metrics in area based approach, point filtering, artificial point reduction,
classification from geographic data, normalization, individual tree segmentation
and other manipulations.
