Odm: No warning if EXIF tags are missing

[elgarbe]

Hi, I have two datasets from the same place but taking with different techniques.
I'm running ODM with docker:
docker run -ti --rm -v /my/project:/datasets/code opendronemap/opendronemap --project-path /datasets under ubuntu 16

I obtain good orthoimage with the first dataset, but not with the second one.
I attached a link to them

can someone tell me what is wrong with the second dataset?

Hey @elgarbe :hand: looks like the model is flipped upside down.

Looks like this is caused by some of your images which are missing the altitude values.

Notice the GPS Altitude field.

I wonder if we should have better checks sanity checks and catch these problems early in the pipeline.

[elgarbe]

ok, but in the first dataset I have missing altitude data on some images but the result is good. I don't get a odm_georeferencing becose of this.

how can I put altitude data by hand?

thank!

Can ODM process images with no EXIF data at all? This would be useful if extracting frames\images from video to use for 3D modeling.

[smathermather]

ODM can process with no EXIF data. It will create a 3D model, but no real orthophoto an no georeferencing.

I think this can be closed:

• We have warnings for missing GPS tags
• we have support for pseudo-georeferencing for non-georeferenced datasets.
