This document specifies guidelines to improve data quality by cleansing sensor data anomalies that affect low inherent quality characteristics.

The following are within the scope of this document:

• principles for sensor data cleansing;
• the process for sensor data cleansing;
• implementation requirements for sensor data cleansing;
• list of data anomaly detection and repair methods (see Annex B);
• examples of sensor data cleansing (see Annex C).

The following are outside the scope of this document:

• algorithms or detailed methods to detect and repair data anomalies;
• the process of sensor data cleansing for real time processing.
