Pixel Quality Mask

Products are delivered with a pixel quality mask raster file generated by Wyvern's QA system in Cloud-Optimized GeoTIFF (COG) format raster file with LZW compression that has unsigned 8-bit byte (uint8) data type. The pixel quality mask raster has the same number of bands as the image data GeoTIFF (i.e. 23-bands for Dragonette-001 and 31-bands for other Dragonette satellites).

Each band of the pixel quality mask raster indicates whether the corresponding pixel in the image data raster has a known pixel quality condition. The value of the pixel indicates which quality condition is present.
