NITF PIA TREs Background
NITF PIA TREs Background
Profile for Imagery Access and Profile for Imagery Archive (PIA) TREs are used to hold
information required by the Standards Profile for Imagery Access (SPIA). A variety of
government agencies require these TREs in NITF image products.
There are 10 unique PIA TREs; newer PIA TREs are labeled Profile for Imagery Access, and
older PIA TREs are labeled Profile for Imagery Archive.
You can edit, delete, and save both sets of PIA TREs in NITF files, but you can only create the
Profile for Imagery Access TREs shown in the following table. You can create the TREs with user-defined
default values using NITF Preferences, and you can save (pack) these to an output
NITF file. The software updates PIAPRC and PIAPRD TREs with the current date and time when you
create NITF output.
