The horizon dip measurement is the angle between the horizontal (the line perpendicular to the vertical at a specific point) and the apparent horizon.
On a globe, we would expect this angle to increase with increasing altitude, because the horizon would drop away with the curve.
On a flat earth, we would expect the horizon to always "rise to eye level".
This page is a gallery of photos showing the measured dip of the horizon from horizontal.
Instructions
If you want to submit your own image, email dip@mctoon.net Please include the following details with your submission:
1. A clearly visible horizon (ideally, no clouds at, or near the horizon)
2. An instrumented graphic overlay showing true horizontal
3. The name of the device generating the graphic overlay
3. Altitude at time of photo
4. Image Source/Credit. Please indicate if you want to be credited and how. We do not wish to dox anyone but we do want to appropriately give credit where it is due.
