Fig. 15

a Colour image derived from the spectral image cube and b 880 nm NIR image of ‘Area 31’ of the Selden map near Banjarmasin. Land has been painted over what used to be the sea (waves painted in copper green show up dark in the NIR image). The bottom straight line seems to be a trade route that was drawn but later abandoned; c Colour image derived from the spectral image cube and d 880 nm NIR image of ‘Area 34’ on the Selden map in Fig. 1 between Banjarmasin on the island of Kalimantan and Cirebon on Java in Indonesia. Land painted in fine black drawings has been overpainted in green; e Colour image derived from the spectral image cube and f 880 nm NIR image of ‘Area 35’ on the Selden map in Fig. 1 near Banda in the Banda sea in Indonesia. The thin lines are more consistent with drawings on land while the thicker lines denote wave patterns in the sea. Land seems to have been overpainted to represent the sea
