Abstract :
Two JERS-1 differential interferograms were analyzed over a boreal test site with forests in northern Sweden. Although the 44-day repeat-orbit, the coherence was adequate to generate one JERS-1 DEM. The RMS error was 7.9 m at 50 m postings. The extra height introduced by forest covers was close to the real tree height in the area
