Question about meter/pixel information for Visual Terrain Relative Navigation Dataset(Helicopter dataset)

[euncheolChoi]

Thank you for sharing great dataset.
Now I'm trying to recover approximate metric unit translation from consequtive two images using Homography.
For example, if translation btw two images(query 00001.png, query 00004.png) is (10pixel, 30pixel), i want to recover approximate metric unit translation using meter/pixel scale information.

So, I would like to request meter/pixel information for the duration of the flight path if that information exists. (for both aerial / satellite caes.)
Thank you in advance.
