Usable Data Mask

Products are delivered with a usable data 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 usable data mask raster has two bands:

  • Band 1: Clear Mask – a value of 1 (one) indicates the pixel is clear; a value of 0 (zero) indicates the pixel is not clear and is one of the remaining classes; a value of 255 indicates a NoData pixel such as image collar border pixels.
  • Band 2: Cloud Mask – a value of 1 (one) indicates the pixel is cloudy; a value of 0 (zero) indicates the pixel is not cloudy; a value of 255 indicates a NoData pixel such as image collar border pixels.
