I know this doesn't help, but we have exquisite 3D laser maps of every detail of Notre Dame, thanks to the incredible work of @Vassar art historian Andrew Tallon. Prof Tallon passed away last November, but his work will be absolutely crucial https://t.co/YJl3XXUZTg? Hannah Groch-Begley (@grouchybagels) April 15, 2019
?You never know what questions you?re going to need to ask,? says Michael Rogers, a professor at Ithaca College who specializes in laser scanning and preservation. ?Think about the work that?ll take place at Notre Dame. They?ll need to know a whole range of things they can?t think of yet. Someb...
