<p dir="ltr">Hi Sergey - try reprojecting your source las file into a projected (in metres) system and running again.</p>
<p dir="ltr">PDAL/GDAL pass projections through. Your input data are in degrees, your output resolution is interpreted as the same unit, so resolution 1.0 is interpreted as '1 degree'.</p>
<p dir="ltr">Hope that helps,</p>
