Processing levels. A means of describing the way remote sensing digital data are processed from raw or engineering units to informational geophysical products. These are typically differentiated by numeric (or sometimes alphabetical) hierarchies, from Level Zero, indicating engineering units or the data from the actual sensor system, to Level Four indicating geophysical products. Typically processing levels are applied to satellite data streams, but they have been utilized in other forms of remote sensing data.


Processing levels as used in remote sensing activities are a methodology for differentiating raw (low) from more highly processed forms of digital data, typically collected by satellite systems. The practice of defining processing levels originates from the space physics research community early in the 1970s civilian satellite research era. First references to processing levels within the US remote sensing community are traced to the Committee on Data...
