Admissibility & Chain of Custody

How we capture matters as much as what we capture.

An aerial shot only helps a case if it can be authenticated. Here is exactly how we document sites and scenes so the record holds up under scrutiny.

The short answer

Whether a specific piece of evidence is admissible is a decision for the attorney and the court. Our job is to make sure it can be: we capture and preserve every scene with documented workflow and maintain the original data we can account for — the kind of record that stands up to authentication and questioning. That work is led by a licensed private investigator with experience testifying, not just a drone pilot taking photos.

Our Process

Six steps, one unbroken chain.

Every forensic engagement follows the same documented process, from first contact to courtroom-ready delivery.

01

Scope & Authorization

Before any flight, we confirm the legal purpose, the site, airspace requirements, and any authorizations needed — and we document the engagement from the outset.

02

Controlled Capture

A licensed investigator captures the scene or site with recorded parameters: equipment, settings, timestamps, weather, GPS positioning, and personnel present.

03

Original Data Preservation

Raw, unaltered source data is preserved and secured. Working copies are used for processing so the original evidence is never modified.

04

Documented Processing

Orthomosaics, models, and measurements are produced with a recorded, repeatable methodology — so results can be independently understood and verified.

05

Secure Storage

Data is stored securely and only accessible by team members. We can account for how files are handled from capture through delivery.

06

Testimony-Ready Delivery

Deliverables arrive with the documentation that supports authentication — and, when needed, a qualified witness who can testify to how they were made.

Questions

Admissibility, answered.

How do you document and preserve your data?
We keep a record of who captured the data and how. Original files are preserved and we work from copies — so the record of how the data was handled is complete and available if it's ever questioned. Using Pix4D allows for an audit trail for the processing of data and this software is also utilized by many law enforcement agencies, reducing scrutiny in defense cases.
What do you hand off with the deliverables?
Along with the models and imagery, we can provide a detailed report of our methodology from when we arrive on scene to the end of data processing — the supporting record an attorney needs to authenticate it.
Can you testify about your work?
Yes. Our documentation is led by a licensed investigator with experience testifying, who can take the stand and explain capture methodology, data handling, and processing.
Do you alter or enhance the imagery?
We preserve original data unaltered and process working copies using documented, disclosed methods. We do not manipulate evidence; any processing is repeatable and explainable. Pix4D maintains a processing log of all steps performed, including any data cleanup, so the full workflow is auditable.

This page explains our documentation methodology and is not legal advice. Admissibility is decided by the court and depends on the facts of each matter and applicable rules of evidence.

Have a case in need of scene reconstruction?

Bring us in early. The sooner we scope the case and capture the scene, the stronger and cleaner the record.
