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.
Pixel Value | Description |
---|---|
0 | No documented pixel quality condition |
1 | The pixel is interpolated |
255 | NoData |
