spectrozonal. The average height of survey was 200-350km. The average scale of
survey was 1:650,000-1:1,200,000. The camera had spectral zones with a range of:
570-680, 680-810nm for spectrozonal & 635-690, 810-900, 515-565, 460-505,
580-800, 400-700nm for multizonal. The frame size is 180x180mm. The area covered
on the ground is 117x117km or 216x216km. The longitudinal overlap of images is
60%. KFA-1000 cameras were typically mounted on (Russian) Resurs-F2
