    Spent the week redrawing a 1:25000 coastline by hand. The shoreline has moved 40 metres inland since the 1984 survey.

    • Is the 1984 survey digitised anywhere? I would love to run the two through a diff.

    • The hand-drawn linework is beautiful. Are you inking these on vellum?

    Found these from the Svalbard trip. You were holding the theodolite backwards.
