Hi Richard, The Historic England aerial photography team have been working on a similar sort of project which they recently released (see https://historicengland.org.uk/whats-new/news/new-virtual-aerial-map-allows-everyone-to-explore-englands-archaeology-from-the-air/). Perhaps they might be able to provide some advice on how they did it? There's an email address at https://historicengland.org.uk/research/methods/airborne-remote-sensing/.
