Scanning the Miranda Map

Speaking of scanning old maps. The State Library of New South Wales, Australia is scanning its copy of Jozeph da Costa e Miranda’s 1706 world map with a state-of-the-art high resolution scanner.

This digitisation process combines high resolution scanning, up to 1200 dpi, with precise lighting technique and incredibly accurate colour rendition. This process is ideal for scanning really large, long items like this map,  panoramas and items with high levels of fine detail.  The files captured at these resolutions allow up to 50× enlargement, making them excellent sources for detailed investigation into aspects of the physical substrate of the item and for innovative multimedia exhibition and display.

The map was scanned in 15cm sections and will be stitched together to create an exceptionally accurate and detailed high resolution file.
