Define the purpose and record owner
Identify the requesting organization, assignment, collection purpose, responsible record owner, and intended users. Operational reference imagery may have different requirements from potential evidence, training material, mapping data, public information, or a contractor deliverable.
IRIS Network should not make a legal classification for an agency. The agency records officer, investigator, counsel, public-information function, or other authorized official determines the governing policy and release requirements.
Separate originals from working products
Preserve original files when the assignment or agency policy requires it. Editing, annotation, compression, cropping, mosaicking, enhancement, and report placement should occur on clearly identified working copies or derived products. The organization should be able to distinguish what the aircraft recorded from what was later processed.
Time settings, aircraft and sensor identifiers, flight or assignment reference, transfer source, and relevant location context should be recorded consistently. Do not rely on a filename alone to explain the file.
- Original capture
- Working copy
- Annotated or enhanced image
- Map/model/report product
- Transfer record
- Release or disclosure copy
Protect integrity and document transfer
Digital files are easy to copy and alter. When integrity matters, establish a checksum or other fixity record, preserve the transfer source and destination, and document who received the material and when. An agency evidence or records system may already provide these controls.
Do not email unrestricted public links to sensitive imagery. Use an approved transfer location, limit access to authorized users, and avoid placing active incident identifiers, credentials, or access tokens in public URLs.
Set access, retention, and deletion rules
Define who may view, download, redistribute, annotate, release, or delete each category. Viewer access, working storage, original preservation, logs, and backups may have different retention periods. A provider should not retain mission material indefinitely merely because storage is available.
Revocation and deletion should be documented, including copies on field devices, editing workstations, cloud storage, removable media, and temporary transfer locations. Legal holds, public-record duties, case requirements, grants, contracts, and agency schedules may override a routine deletion target.
Review before public or training use
A useful operational image may still expose a person, address, plate, medical event, tactic, map layer, radio display, access point, or sensitive facility. Public-information and training use should receive a separate release review rather than inheriting operational access approval.
Redaction or de-identification produces a new derivative; it does not alter the handling requirements of the original. Record the source and approval for the released version.
Questions agencies ask
Frequently asked questions
Should every UAS image be treated as evidence?
Not automatically. The requesting agency determines the record classification based on collection purpose, incident context, policy, law, and later use. Potential evidence should be handled under the agency process from the point that need is identified.
Why keep a checksum?
A cryptographic checksum can help demonstrate whether a digital file changed after a baseline was recorded. It supports integrity controls but does not replace chain-of-custody documentation or agency policy.
Can operational imagery be reused on a website or in training?
Only after an authorized review confirms the organization has permission and that sensitive, private, investigative, safety, and public-record concerns have been addressed.
