This paper is about the design of the NCEDC schema for the hardware tracking. This schema was designed to be able to track any station from the sensor to the datalogger by their serial numbers. It can also generate automatically the instrument responses schema.

There are 28 relations in the schema. The information stored in these relations includes:

Responses description (high-pass, low-pass, FIR filters; Poles & zeros; Polynomial).
Sensors and components information.
Analog filters, amplifiers information.
Dataloggers, digitizers information.
Dataloggers logical channels information.
Tracking information.
