High Resolution Satellite imagery
Basic Product (level 1B)

 

RapidEye Basic Product (Level 1B) data is radiometric corrected, sensor corrected and band aligned providing imagery as seen from the spacecraft without any further corrections for any terrain distortions. The imagery data is accompanied by all the necessary metadata that when combined with user supplied DEMs and GCPs allows for custom processing the data into a geo- corrected form to suit the user's needs. The imagery is delivered as a group of single band NITF files with a resolution of 6.5 meters GSD at nadir.

The radiometric corrections applied to this product are:

  • Correction of relative differences of the radiometric response between detectors
  • Non-responsive detector filling which fills nulls values from detectors that are no longer responding
  • Conversion to absolute radiometric values based on calibration coefficients

The geometric sensor corrections applied to this product correct for:

  • Internal detector geometry which combines the two sensor chipsets into a virtual array
  • Optical distortions caused by sensor optics
  • Registration of all bands together to ensure all bands line up with each other correctly
