Note I said "at a similar latitude".
A satellite at a given inclination will trace out a ground path oscillating back and forth between D degrees north and D degrees south, where D is its inclination, with latitude varying sinusoidally with time. So it will spend different amounts of time at different latitudes, hence choice of inclination depending heavily on observation/communication target.
However, for any given latitude it will spend an equal amount of time at each longitude (east-west location) as the Earth rotates under its orbit. See e.g. https://en.wikipedia.org/wiki/Ground_track https://en.wikipedia.org/wiki/Ground_track
So for example, any satellite that images Georgia (the US state) or Taiwan will spend an approximately equal amount of time over Lebanon and Israel.
- qart 5y agoThere are so many incorrect and vague things here, but rather than listing them out, I point back to my counter examples. Zooming in on Kumasi, Ghana should show you why you're wrong. Look at the mosaic lines. There are both N/S lines of disparity as well as E/W lines of disparity of resolution. Use your own example, if you wish. Zoom in on Taiwan, and look at the cars. Next, zoom in on King Abdullah Economic City, Saudi Arabia at the same latitude. Look for cars there. Verify if your explanation fits the data.
