4. “… and now it's you who can rediscover these
documents, put them on modern maps, and
share them with the future generations.”
“It were the dreams and desires of travellers,
monarchs and generals…”
“… the hands of artists and cartographers,
who created these works…”

6. Why? 5 minutes from a volunteer:
• Visualization of the old maps in 3D
space and as overlays
• New ways how to discover maps with
geographical search
• Enrichment of the metadata of maps
required for research and education
