Contact Ground Truth & Governance

For general correspondence, technical questions, source-file requests, corrections or enquiries concerning the archive:

The project welcomes contact from regulators, researchers, technical specialists, journalists, local residents and others with relevant information or expertise.

Source files and supporting material

Original photographs, native image files, metadata and supporting measurement data are retained within the project archive.

Where practicable, requests for source material will be considered for:

• professional or regulatory review;
• independent technical assessment;
• academic research;
• verification of a published figure or observation;
• responsible journalistic examination.

Please identify the relevant report, version, figure, date or location, together with the intended purpose of the request. This helps locate the correct material within a large archive.

Corrections and additional evidence

Factual corrections, alternative explanations and independently sourced evidence are welcome.

Please distinguish, where possible, between:

• a factual or transcription error;
• additional contextual information;
• a different interpretation of the same evidence;
• new evidence that may alter the existing interpretation.

Material changes will be recorded through report updates or correction notes rather than silently replacing the published record.

Media and reproduction enquiries

Please contact the project before publishing altered, cropped, annotated or colour-adjusted versions of original photographs or video.

When requesting permission, include the intended publication, image or video concerned, proposed alterations and whether the use is commercial or non-commercial.
