 Since version 0.9.9 ODM has basic support for radiometric normalization, which is able to generate reflectance orthophotos from multispectral cameras. Multispectral cameras capture multiple shots of the scene using different band sensors.

+Supported Sensors
+-----------------
 
 While we aim to support as many cameras as possible, multispectral support has been developed using the following cameras, so they will work better:
 
- * `MicaSense RedEdge-MX and Altum <https://www.micasense.com/>`_
- * `Sentera 6X <https://sentera.com/products/fieldcapture/sensors/6x/>`_
- * `DJI Phantom 4 Multispectral <https://www.dji.com/p4-multispectral>`_
+ * `MicaSense RedEdge-MX and Altum <https://www.micasense.com/>`_ 
+ * `Sentera 6X <https://sentera.com/products/fieldcapture/sensors/6x/>`_ (as of ODM version 1.0.1)
+ * `DJI Phantom 4 Multispectral <https://www.dji.com/p4-multispectral>`_ (as of ODM version 2.8.8)
+ * `DJI Mavic 3 Multispectral <https://ag.dji.com/mavic-3-m>`_ (as of ODM version 3.5.3)
 
 Other cameras might also work. You can help us expand this list by `sharing datasets <https://community.opendronemap.org/c/datasets/10>`_ captured with other cameras.
 
-Usage
------
+Creating Orthophotos from Multispectral Data
+-------------------------------------------
 
-Process all the images from all bands at once (do not separate the bands into multiple folders) and pass the `--radiometric-calibration` parameter to enable radiometric normalization. If the images are part of a multi-camera setup, the resulting orthophoto will have N bands, one for each camera (+ alpha).
+For supported sensors listed above (and likley other sensors), users can process multipsectral data in the same manner as visible light images. Images from all sensor bands should be processed at once (do not separate the bands into multiple folders). Users have the option to pass the ``--radiometric-calibration`` parameter with options ``camera`` or ``camera+sun`` to enable radiometric normalization. If the images are part of a multi-camera setup, the resulting orthophoto will have N bands, one for each camera (+ alpha).
 
+NDVI and other vegetation indices can be calculated from these stitched orthophotos using software such as `qGIS <https://www.qgis.org/>`_

  * all JPGs from the NDRE directory should be renamed with the exact following pattern 0000X_NIR.jpg. No extra '_' should be present in the file names ie 10_51_14_IMG_00008.jpg => 00008_NIR.jpg
  * all JPGs from the nRGB directory should be renamed with the exact following pattern 0000X_RGB.jpg. No extra '_' should be present in the file names ie 10_51_14_IMG_00023.jpg => 00023_RGB.jpg
