[pdal] Writing multi-band rasters

[Andreas Yankopolus]

Andrew,

> PDAL doesn't support this, but you can chain writers to get separate rasters. I assume GDAL has some VRT magic to merge the separate tiffs into a multi-band:

This is perfect. I can put the PDAL command inside a bash script that also calls GDAL to merge the scratch rasters into the multi-band final raster before cleaning them up.

Cheers,

Andreas
