### Calculating area covered by a photo from the Raspberry Pi Camera Module

Hi, I was wondering if anyone could help our team with this question as we have got into stage two of the Astro Pi competition. What area of ground coverage would we get from a single photo taken from the ISS? We would like to have photos of the entire flight path and we need to know how often to take a photo to get complete coverage. Please help.

Here's the spec showing coverage angles, do you know the height of the iss?

This site https://www.scantips.com/lights/fieldofview.html suggests the following... 494km x 370km.

Worth getting a second opinion!

There should be photos from the ISS from last year's event (or the year before maybe)
Where, I don't know but ask the organisers.
You then have something to compare against.
