Ordnance Survey (OS) has captured aerial imagery of Great Britain for decades to support the maintenance of its national datasets. Once new imagery is captured, it is processed (Change Detection and Automated Feature Extraction), and then carefully archived and preserved (i.e. locked in a cupboard). The latest imagery is used to support existing OS products, but the older imagery is left alone. These image archives contain a visual record of how the UK has changed over time which could be very valuable!

This talk explores how this imagery archive is currently preserved within an open-source Fedora Commons repository, and how it could evolve into a discoverable geospatial asset using the OGC standard STAC.
