It should generate a better one.\r\n\r\nAlso, the existing documentation should be updated to 1) clarify that you don't need to pre-create the index file and 2) remove the GDAL warning since GDAL is always part of PDAL now.\r\n\r\nAlso, it looks like --tindex isn't set as a positional option, which is in contradiction with the documentation."}}
