The Issue

A Portuguese Nautical Chart of cartographer Luís Teixeira, from 1585 (XVI century), placed at the Navy Museum in Lisbon, was to be studied by a researcher for an European project. The Nautical Chart was in very poor conditions and damaged, and almost its pigmentation was almost invisible.

Result

Portuguese old nautical chart

The images were practically invisible to the eye, but with our XpeCAM X01, it was possible to “read” the Nautical Chart again. The information became visible at UV light (370nm). By gaining a new life, the Nautical Chart provided such new information that the research had to be retraced.
