🆕Code lists

A code list is a controlled set of allowable labels or codes represented as an alphanumeric attribute. The pages in this section show the code lists used within the OS Multi-modal Routing Network (MRN). Some of the code lists apply to attributes of multiple feature types, whereas others will only apply to attributes of one feature type.

The pages in this section display the code lists in alphabetical order, with one code list provided per page.
