In 2015, I•GIS scanned thousands of unique aerial photos of Greenland from the 1930s.
In the project for the Danish Geodata Agency I·GIS scanned 15.000 historical photos
and registered its meta data. The original film rolls from the 1930s were made of
cellulose nitrate, which can, in a worst case scenario, ignite spontaneously. The
dangerous material made it necessary for I·GIS to establish scanning facilities
especially for this project. The aerial photos document what has happened to the
glaciers and the ice sheets in the past 80 years.
