NigeriaSat-2 Satellite Image Test Report


Published: 2012-8-10  Source by: Original


      The test is divided into two parts, including NigeriaSat-2 satellite data color test and positioning accuracy testing. We test the NigeriaSat-2 satellite data by using the way of the geometry correction which needs select 30 control points and take the UTM coordinates and DEM data (WGS84 coordinate system) as control reference data.

      The preliminary conclusions of NigeriaSat-2 satellite data test:
      (1) The quality of 2.5-meter satellite image of NigeriaSat-2 is very good. The color is normal and we can easily identify surface features.
      (2) NigeriaSat-2 satellite can satisfy the requirement of accuracy through the correction with DEM and control points .
