Phantom 4 Multispectral
« on: December 02, 2019, 04:52:32 PM »
Hi all,

Just got delivery of the Phantom 4 Multispectral. Would anyone here be interested in a sample dataset? I am uploading it to my Google Drive so if anyone wants it let me know and I will share a link here.

Does anyone have one yet? Any recommended workflow?

Hello sakaic,

It would be helpful, if you can share the dataset acquired with the multispectral sensors, we'll check, if anything should be developed on our side to support that.

I would be interested too, thank you. I teach GIS and Remote Sensing (for archaeology) and would love to play around with the data. Cheers!

Hi Guys,

You can download it here

https://drive.google.com/drive/folders/1FbQgvme0aisRcknUrhB4u3hbgY8fWn2x?usp=sharing

It stitches fine but I guess at the moment reflectance calibration is not possible yet.

Let me if there are problems downloading. My responses will be slow as I am in the field with a mapping mission.

Cheers

Hello sakaic,

Thank you for sharing the dataset.

We'll study the available information related to sun sensor meta-data and at some point will add the support for it and proper reflectance calibration operation.

In the current dataset it seems that sun sensor relative rotation and sun sensor absolute orientation angles are not available in the meta information.

Hi Alexey,

Is it possible to use the FlightRollDegree, FlightPitchDegree and FlightYawDegree data in the XMP data since the sunshine sensor is bolted directly on the RTK antenna?
