TAGGED RECORD EXTENSION (TRE) Fields
| Tagged Record Extension (TRE) is a collection of data fields that provides space within the NITF file structure for adding, as yet unspecified, future capabilities to the standard. The TRE is used to extend NITF by adding additional attributes to designated fields in the NITF file header and in the image, text, and graphic subheaders. Each TRE consists of three required fields that are defined in MIL-STD-2500C, Table A-7. There are two TRE types: Controlled Extensions (CE) and Registered Extensions (RE). The principles are described below and illustrated in MIL-STD-2500C, Figure 14. |
