Sequoia Images Plant health view

[Hubertus_Paetow]

System: Ryzen 7 2700X; 48 GB DDR3, 256 GB SSD
Latest Webodm/docker on Ubuntu 20.04.1 LTS, Chrome 85.0.4183.83
Images from parrot sequoia 16-bit Tiff, gre/red/nir bands, 795 images / 265 views
Options: radiometric-calibration: camera+sun, orthophoto-resolution: 5, dem-resolution: 5, ignore-gsd: true, depthmap-resolution: 1000, texturing-data-term: area

Processing finished after 1:56 with great result;

The GEOTIFF consists of 4 Bands - GRE/REB/NIR and an alpha channel. I can process the GEOTIFF in qgis and calculate the NDVI- Image.
But when i try to switch to “plant health” view in the webodm map, i get a message “bad request”. The process (webapp) message is:
WARNING Bad Request: /api/projects/5/tasks/58011f60-59a3-4124-af50-fc32a2a65e64/orthophoto/metadata
Any suggestions?

Perhaps a bug. Can you share the all.zip file from your task?

Definitely a bug. It should be resolved with https://github.com/OpenDroneMap/WebODM/pull/907

Wait a few hours, update, then see if the issue is resolved.

It works. Great.

Thanks a lot.

Hi Hubertus,
To generate the NDVI map from Parrot Sequoia, can you please tell me what parameters of “Filter” you choose? As you may know, the bands of this multispectral sensor are ordered as Green/Red/Re/NIR, however, I did not find the Filter option as G/R/Re/N on WebODM plant health settings

Thanks.

Hi Piero,

I submitted the request by add “GRReN” in the Filter Option.
