Landsat Data Continuity Mission or Landsat 8 has been long awaited since the failure of the Scan Line Corrector onboard the Landsat ETM+ satellite sensor, just 4 years after its launch in 1999. There was 22% data loss in each scene which severely affected efforts on Climate change and various other Environmental studies. NASA was… Continue reading Landsat 8 and Landsat 7 comparison, First Look
