Recently, Michael Cory contacted me about the post and the image, to use it in his fortcoming talk on mapping.
He is giving a talk on the Ordnance Survey and its early 19th century baseline established on the shores of Lough Foyle which formed the basis for all measurements between places in Ireland, Britain and further afield for the best part of two centuries.
Above here, an intense double rainbow looking across Benone towards Magilligan and beyond, Inishowen in Donegal.
Michael is a land surveyor who has mapped many portions of the world's more exotic corners, his talk is in Dublin on the 13th of June 2024 at 18:30 in Phoenix Park entitled From Limelight to Satellite: The Importance of the Lough Foyle Baseline.
