HRS instrument on SPOT 5

HRS instrument on SPOT 5 is dedicated to simultaneous stereopairs acquisition:

  • 2 telescopes, one pointing forward and one aft of nadir, at a fixed angle of 20°
  • acquisition interval: 90 seconds along the track
  • an imaging swath of 600 km x 120 km (72,000 km2)
  • base/height ratio (B/H) of 0.8


A digital elevation model (DEM) is a file containing elevation values distributed on a uniform grid of an area of interest.
SPOT DEMs are produced by automatic correlation of stereopairs acquired by HRS.
