Simon, thanks for the suggestion.

My GPS EXIF data is all accurate from my testing. I've run it through
Photoscan multiple times and have tried ODM a few times over the past
several days. If you want to see the dataset you can find it here:

This includes the source imagery (95 files) plus the output geotiff from
Photoscan.
