Hi Dan,
Thanks for sharing. Could you post an example of how the base layer might be changed for a IIIF tiled image?
e.g. https://dlc.services/iiif-img/48/24/e7a4f78a-64bd-41fd-a760-e85823ed98dc/info.json
Thanks

Would it be possible to send the geojson to a form attachment, rather than exporting it?
