Elevation error

The image i submitted stitched together well and the georeferencing seems adequate for the GPS control (DJI Mavic 2 Pro), but the elevation values are way off and range (minus the trees) about 300 feet when it is basically flat terrain.  I would think the elevation data (relative) should be pretty tight.  Am I missing something?

I don't see an account in the system with your name so I can't look you up but the issue is almost certainly that you didn't include a ground reference image and the GPS derived numbers are being used instead.

There is a note to include this image above the uploader panel where you select your images.

I am working with a co-worker that made the account an bought points.  I did the flying. (EBerntsen@kalispeltribe.com)

I see.  I excluded the ground image as I assumed it was just for reference.  I guess that pretty much blew that exercise.  Glad we only processed a subset of the data.

Thanks, Jim
