<div class="">You *could* crawl the metadata object to find the las header, BUT it’s a bad idea: the values in the header can’t be relied on, as the generating apps often get it wrong. LAS is notorious on this one. Trust me. :-) (trivial example: sometimes
the min/max corresponds to the data *before* they did some cleaning to remove noise points……..)</div>

<div class="">Furthermore, because PDAL is a general / format-independent library, it tends to only expose as 1st class citizens the info that it “knows” is always true and will always be there for all formats.</div>

Hi,<br class="">
<br class="">
This is related to Michael's issue post here:<span class="Apple-converted-space"> </span><a href="https://github.com/PDAL/PDAL/issues/569" class="">https://github.com/PDAL/PDAL/issues/569</a>. I need access to min/max bounds on quantities like intensity values,
geographic bounds, etc (specifically in las files but should be generalized). I know those values are available in the las header. Yet it seems that to obtain these "stats", I need to employ a stats filter and read all the points. Is there another mechanism
for quickly reading certain general properties (like bounds) that may be available from the header?<br class="">
<br class="">
Thanks,<br class="">
Oscar<br class="">
