<p class="MsoNormal">A more general question would be… is it common or considered okay for a pdal filter to give different output like this when in normal versus streaming mode?<o:p></o:p></p>

<p class="MsoNormal">It looks like the filter will keep all the points if you run in standard mode. Maybe that will help.

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">filters.colorization will actually skip away points that do not correspond to a position from the input the raster file. This then causes loss of points in the output if the input
raster isn’t georeferenced correctly to the point cloud. I thought it would make sense to add a “keep_outside” option and was playing around with that when I noticed that this only happens when running in streaming mode. When running in normal mode all points
are kept. Is this difference in output between streaming mode and normal mode expected behaviour?
