- Description: Feature code
- Definition: Numeric value that encodes a set of characteristics for a type of feature. This five-digit code has two parts: the first three digits encode the Feature Type (FType); the last two digits encode values for a unique set of characteristics associated with the Feature Type. The set of characteristics may be single valued or multi-valued.
