Bad bands interpretation in Multispectral Sequoia orthomosaic map

[andrey.d]

Hello,


I use this manual https://training.fws.gov/courses/references/tutorials/geospatial/CSP7304/2016documents/HandsOn_Afternoon/UAS/UAS%20II%20Post%20Processing/PhotoScan%20Processing%20Procedures%20MicaSense%20Feb%202016.pdf
 to stitch Multispectral Sequoia images into a map. The result looks without proper color information.

The resulting map has the problem with bands interpretation: the first band is Gray, 2-4 are Undefined, 5-th is Alfa.


As input, I have set of one channel images for like
IMG_xxx_GRE.TIF, 
IMG_xxx_REG.TIF
IMG_xxx_RED.TIF,
IMG_xxx_NIR.TIF.

Hello andrey.d,

Do you mean that some meta data is missing for the exported orthomosaic generated from Sequoia images?

I mean result map was in the incorrect format: no Red, Green, Blue, NIR channel.
There is 5 band in tiff file, but the first band is Gray, 2, 3 and 4  bands are Undefined.

I think I find what is the problem.
Unexpected for me the Sequoia Multispectral Camera has only Green, Red, Red edge, NIR channels without Blue.
So Agisoft Photoscan couldn't make RGB result tiff map.

I suppose in this case Agisoft Photoscan should work better and set something like that as Color Interpretation:
Band 1  ColorInterp=Green
Band 2  ColorInterp=Red
Band 3  ColorInterp=Red_edge
Band 4  ColorInterp=NIR
