Sometimes when you are georeferencing, you have to take executive decisions. Last week one of our volunteers stumbled upon this map of ‘Poelau Kisser’, according to the catalog record an island in the Maluku Tenggara area. Soon the small island of Kisar was found. It is located just northeast of Timor.
Now the georeferener looked at the island and the map and noticed the island on Google Maps looked much more like the pencil sketch than like the printed map. She was in doubt which map to georeference, but made the ‘executive decision’ to georeference the printed map, because it is interesting to see how difficult it must have been in the 1910’s to map a tiny island. Looking at the Google terrain map it seems highly unlikely that the island had a different shape back then.
One wonders when the penciled map was drawn. It seems the user started by correcting the printed map, but soon found out the map was so far from reality, it was better to sketch a new map on a blank part of the page. The pencil corrections are probably made by Gerret Pieter Rouffaer, map librarian at KITLV and considered the last explorer of Indonesia (in his recently published biography). In 1910 he traveled to Timor from where he explored the surrounding islands.
