<div dir="ltr">Hi Andrew,<div><br></div><div>Thanks for the reply.<div><br></div><div>As I mentioned, I found that most of the projects are very big (10's of GB to over 100 Gb!) but I found one relatively small one (~900 MB) but "pdal info" was happy with it. I found another one that's just over a 1Gb and PDAL could read that too.</div><div><br></div><div>Could there be some sort of size assumption in PDAL or readers.e57, like maybe a 32-bit size or offset somewhere? The readers.e57 page in the docs mentions a couple of caveats about this format but I imagine the tools would warn if one of these problems was encountered, right?</div><div><br></div><div>I randomly tried another relatively small (for CyArk; ~4 GB) file and "pdal info <file> --metadata" returned a different error:</div><div><br></div><div>>pdal info kz88-9d21_lidar_photogrammetry.e57 --metadata<br>PDAL: readers.e57: 29 : fileName=kz88-9d21_lidar_photogrammetry.e57 header.filePhysicalLength=4803256320 file->length=508289024<br></div><div><br></div><div>Anyone may download it by starting at <a href="https://openheritage3d.org/project_thankyou.php?id=ck42-e122">https://openheritage3d.org/project_thankyou.php?id=ck42-e122</a> and following the "Download" link (which leads to a form and then they mail you a real link to a .zip.)</div><div><br></div><div>Thanks for any ideas,</div><div><br></div><div>carl</div><div><br></div><div><br></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Mar 19, 2020 at 12:16 PM Andrew Bell <<a href="mailto:andrew.bell.ia@gmail.com">andrew.bell.ia@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">If you can make a smaller version of a file available, I'll take a look.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Mar 19, 2020 at 2:40 PM Carl Godkin <<a href="mailto:cgodkin@gmail.com" target="_blank">cgodkin@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi,<div><br></div><div>I am new to PDAL so I hope this isn't a seriously dumb question.
