The band order of raw images from the camera is different than that of geotiff files processed by Atlas cloud.
ALTUM AND REDEDGE RAW IMAGE BAND ORDER
IMG_0500_4.tif (Near Infrared)
IMG_0500_5.tif (Red Edge)
IMG_0500_6.tif (Thermal - Altum only)
This information is also contained within each image's EXIF metadata. The "Band Name" field defines the human readable name (Blue, Green, etc.) while the "Center Wavelength" field defines the center wavelength of the filter for that band, in nanometers (475, 560, etc.)
Atlas Cloud Geotiff Band order:
|4||Red Edge (717nm)|
NOTE: The band order in the file names for the unprocessed source images on the RedEdge camera are different than those exported from Atlas (bands four and five are switched).
Also note that Altum data is NOT able to be processed by Atlas Cloud, which is why Band 6 is not listed in the above table for the band order.
