Just a heads up. Emlid today just released Emlid Studio version 1.8 which retains the aforementioned metadata.


The Emlid workflow geotags the photos, but that wipes the yaw, pitch, roll.
 I assume that I will want this in order to best use Agisoft's photo alignment?

In that case I can pull the latitude and longitude from the Emlid Studio events.pos file into a csv.
The only problem here is there is no associated filename, I can write a little script that pulls the exif data from the original photos and then match them via timestamp.
I am worried this is getting a bit complicated and I missed a simpler solution.

Yes.  Metashape uses those parameters.  Emlid is aware of this and are actively working on Emlid Studio to retain all of that data.  Until then, you need to employ a workaround like you suggested.  You could also use RedToolbox ( in the meantime. It has a nominal fee, and a fully functioning trial.

I have two more questions..
1.  Can I do this when I have already built the ortho and update?  It doesn't seem likely, but just checking which step I need to go back to

If you use the method to write the original exif, including the corrected camera positions, to the images. Then they will be used when ingested by MS.  If you use the original images, and then supply a camera position reference file, yes, you want to do all of that and get everything position wise sorted before having MS process any products.  MS can update the sparse cloud (tie points) based upon updating your changes.  But products beyond that need to be re-done.

A little tip, there is such a function in many web browsers, which is called translator ;) 

Good tip. If you don't read the forum default language you could use it.

As a bonus,you might get participation from a lot more users that have experience with the issue you are having.

Yes.  It looks like that one option will work.

Hi Jake

Agree with Paul.

I would add that if you establish a good base position (via PPP) prior to using the base for RTK for your drone. The correction will be applied to the camera positions in real time.

If you are correcting your base after your drone flight, then you will need to also correct the camera locations. Emlid Studio can do that for you.

When you subsequently fly the same project in different seasons, if you can use your same corrected base position, then no corrections necessary.

The important thing is to get a good base position established.

It seems to be some form of mask.  I get the same behavior with a breakline.   If I turn off the display of shapes, the red masks remain. 

If I change FILL parameter values, you can see that the surface is changing under the mask.  So, the FILL function is probably working.  But for some reason, this RED MASK is also generated over the shape.

Here is a screen recording:

DEM and the polygon both state WGS84.  The shape vertices seem appropriate.

Hi Paul.

Trying other parameters doesn't seem to make a difference in this case, unfortunately.

Referencing this article  (,  I get different behavior.

1. Draw Polygon
2. Open context menu and select DEM > Fill
3. The polygon fills with RED.

 I must be missing a simple step to get the behavior illustrated in the article?

I have no answers Paul.

What ever I'm doing wrong, I'm consistent. A quick look at various projects using a P4P and Evo 2 exhibit similar results.

If you say so, I'm sure I do.  I don't know much about them.  The check point errors are reasonable. So, what can I do to identify what is causing the problems?

Oh, I do get a blank white plot.  I was assuming that there was no plot at all by comparison to what you were getting.
