| Band Name | XMP | Xmp.Camera.BandName | {"Red", Green, " NIR"} | XmpSeq | Name of each band (sequence). Single page image: one name for each band of the image. Multipage image: one band name per image page. (Note: this allows only one band per page, since sequence of sequence is not possible). | https://support.pix4d.com/hc/en-us/articles/206434245-Camera-XMP-Specification#gsc.tab=0 |
| Band Center Wavelength | XMP | Xmp.Camera.CentralWavelength | {660, 550, 800}470 | XmpSeq | Central wavelength of each band in nm. Similar to band names.
