Panchromatic Image

Overview​

An ARD panchromatic image is a single-band black and white image that has been minimally processed for analytics. The following pre-processing steps are applied:

  • Atmospheric compensation
  • Orthorectification to native resolution, as captured by the sensor

Panchromatic images are saved as Cloud Optimized GeoTIFF (COG):

  • processed using GDAL's COG output format using default settings
  • DEFLATE compression
  • NoData pixels are encoded in a mask band
