The bandwidth (also known as FWHM) for your camera model may vary slightly depending on the serial number.
Note that the band order is not exactly in wavelength order (bands 4 and 5 are swapped, and the panchro band is centered between Green and Red). Once the data is processed (such as in Pix4D or Agisoft), the layered GeoTIFF output should be in wavelength order, meaning that processed geotiffs will be as well. However, if you used the image processing library to preprocess the data, the imagery will be in B-G-R-NIR-RE order.
The band information is also contained within tags in each image's EXIF metadata:
- The Band Name tag contains the human-readable name (Blue, Green, etc.).
- The Central Wavelength tag contains the center wavelength of the filter for that band in nanometers (475, 560, etc.).
- The Wavelength FWHM tag contains the bandwidth of the filter (32, 27, etc.). For more information, please refer to How to read and export image metadata with Exiftool.
The file suffix is used in the following file name format:
IMG_ + 4-digit sequential capture number + _ + File Suffix + .tif
So the example IMG_0500_1.tif denotes the Blue image taken during the 500th capture since the last time the camera was power cycled.
For Altum-PT and RedEdge-P:
| File Suffix |
Band Name |
Center Wavelength (nm) |
Bandwidth (nm) |
| 1 | Blue | 475 | 32 |
| 2 | Green | 560 | 27 |
| 6 | Panchro | 634 | 463 |
| 3 | Red | 668 | 14 |
| 5 | Red Edge | 717 | 12 |
| 4 | Near IR | 842 | 57 |
| 7 (Altum-PT Only) | LWIR (Altum-PT Only) | 11 μm | 6 μm |
For RedEdge-P Dual
For RedEdge-MX with serial numbers RX02 or higher or Altum with serial numbers AL05 or higher, refer to the following table:
| File Suffix |
Band Name |
Center Wavelength (nm) |
Bandwidth (nm) |
| 1 | Blue | 475 | 32 |
| 2 | Green | 560 | 27 |
| 3 | Red | 668 | 14 |
| 5 | Red Edge | 717 | 12 |
| 4 | Near IR | 842 | 57 |
| 6 (Altum Only) | LWIR (Altum Only) | 11 μm | 6 μm |
For RedEdge-MX Blue (in the Dual Camera System):
| File Suffix |
Band Name | Center Wavelength (nm) |
Bandwidth (nm) |
| 6 | Coastal Blue | 444 | 28 |
| 7 | Green | 531 | 14 |
| 8 | Red | 650 | 16 |
| 9 | Red Edge | 705 | 10 |
| 10 | Red Edge | 740 | 18 |
Refer to the table below for RedEdge-MX with serial RX01 or lower, Altum with serial AL04 or lower, all RedEdge 3, and all RedEdge-M. The Altum thermal (LWIR) band is unchanged.
| File Suffix |
Band Name |
Center Wavelength (nm) |
Bandwidth (nm) |
| 1 | Blue | 475 | 20 |
| 2 | Green | 560 | 20 |
| 3 | Red | 668 | 10 |
| 5 | Red Edge | 717 | 10 |
| 4 | NIR | 840 | 40 |
| 6 (Altum Only) | LWIR (Altum Only) | 11 μm | 6 μm |
Note: Bandwidth is defined as the width of the filter that lets the light of a certain wavelength pass. In other words, our Blue sensor has a width of 20nm that lets the light of a center wavelength of 475nm pass through.
