Please watch in as high a resolution as you can, so that the 1 pixel width lines are visible! Next time I'll make them thicker.

Having a quick look at Pablosdog's youtu.be/5_xCIryP4QA first observation of the season. In this video I roughly analyze the angular relationship of a point at Mesa Lane vs. the apparent end of the visible water, which should be at the far shoreline. Tide height was not taken into account, and the inputs (including field of view) were estimated based on Google Earth measurements.

Comparing only to a flat plane perspective expectation (ignore the globe references in the display), this should be considered a positive claim for a flat model, rather than a 'not a perfect globe, therefore must be flat' claim. That said, this isn't really about claiming evidence in support of a flat model. This is more just a demonstration of my updated analysis tool - the Swanalyzer, and how it can be used to determine the angular relationships of points within an image. Future analysis will show how they vary from observation to observation (and measuring different heights in the same observation).

Keep in mind that my tool is only 100% accurate provided the inputs are also 100% accurate. I'm not claiming the inputs (such as field of view) for this demonstration are exact, but small errors shouldn't change the overall result by a large degree. I'm happy to re-estimate and show results for any suspected significant errors for the 6 required input values.
