Method to correct satellite data to surface reflectance using scene statistics
A method for correcting top-of-atmosphere reflectance data in high altitude imagery to a ground surface reflectance data. Transmission of light through Earth's atmosphere and its suspended load of aerosol particles degrades light within the visible through near infrared portion of the spectrum. This can severely affect the quality of the data recorded by orbiting Earth observation satellites. The method first measures the degree of atmospheric effects upon reflectance, then reverses these effects to deliver surface reflectance data and imagery cleaned of haze and thin clouds. |

The controller then forms a new superblock from blocks in a spare pool. When the number of blocks is equal to a superblock threshold, the controller attempts to pair the surplus block with another surplus block from the opposite plane according to a die sequence. If the attempt to pair is successful, the controller adds the pair to the spare pool; otherwise, the surplus block is not added to the spare pool. |

Based on measurements of forces and rotational velocity experienced by a drill bit during drilling, drilling behavior is detected and identified. Measurements of forces on a drill bit including torque on bit (TOB), weight on bit (WOB), etc. and measurements of rotational velocity (rotations per minute or RPM) are acquired in real time at the drill bit.
