| Abstract: |
The D4A (Digital Access to Aerial- and Astro-photographic Archives) project aims to acquire the necessary know-how, hardware and software to digitise the astro-photographic collections of the Royal Observatory of Belgium (ROB) and the aerial-photographic collections of the National Geographic Institute and the Royal Museum of Central Africa in collaboration with AGFA-Gevaert, a world-leader in photographic matters. The final design of the “D4A Digitiser” that is being built by the ROB in Brussels is presented. A geometric benchmark testing of different commercial flatbed scanners is given and the results are compared with the requirements needed for the astrometric and photometric data extraction from the digitised images. |
