             abstract = "The Brazilian Institute of Geography and Statistics IBGE has a 
                         vast historical collection of analog aerial photography, stored in 
                         Rio de Janeiro. These photos were the main resources for various 
                         cartographic products published by the institution, mostly 
                         consisted of topographic maps at various scales. To facilitate 
                         searching and accessing this historical data and also to preserve 
                         paper information, once it tends to deteriorate over time, weve 
                         started cataloging information from old schemes which contain the 
                         approximate perspective center of the aerial photos. The first 
                         step consisted in scanning the original schemes. This was a 
                         critical step, considering that in some cases the degradation 
                         stage of paper was already evident. The second step was the 
                         georeferencing process (through the geographical coordinates 
                         collected in the schemes/topographic maps) followed by approximate 
                         perspective center extraction of each photo. So far there were 
                         collected 63,577 points spread across 190 old schemes and 178 
                         topographic maps, with the attributes: photo, flight range and 
                         work block numbers. The subsequent planned stages are: i) collect 
                         the perspective center of other photos using the same 
                         methodological process; ii) survey and fill the attribute table 
                         with others flights information (date, scale, etc.); iii) scanning 
                         process of further analogue photographs; and iv) proceed automatic 
                         registration workflow of the scanned aerial photos.",
