Relationships Between Data Type and Data Level

Each platform can produce multiple data types. To understand data categorization, it is important to clarify the relationship between data type and data level.

Each data type is associated with sets of data that span one more data levels. Each center and platform may have a slightly different concept of data level depending on their data types, and the algorithms used for analysis.

For descriptions of data types and corresponding data levels see Data Types and Data Levels.
