<div dir="ltr">Michael,<div>That seems to have done the trick! I will test against the batch from NOAA later, but I think that looks like the issue. So this version of pdal is not keeping the vertical datum by default when reprojecting, and you need to specify the vertical datum in the projection definition. I can understand why that might be, but I was assuming that the vertical datum would carry over by default.</div><div><br></div><div>Doug</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Nov 14, 2017 at 10:07 AM, Smith, Michael ERDC-RDE-CRREL-NH CIV <span dir="ltr"><<a href="mailto:Michael.Smith@erdc.dren.mil" target="_blank">Michael.Smith@erdc.dren.mil</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p class="MsoNormal">The problem is the z values of all of the point values are have been changed. I had created a raster from the mean value of the ground points from the pdal reprojected data. I then went back to NOAA's site and selected a small subset
to compare and had their engine deliver the points in Albers Meters Conus NAVD88. I imported the points to create a raster in the same way and then subtraced the Z value of the pdal reprojected points from the NOAA reprojected points. The height values
vary by 32-36 m ( see below) .<u></u><u></u></p>
