Welcome to the AragoJ wiki!
Domènec Francesc Joan Aragó, aka François Arago, was a French Catalan mathematician, physicist, geodesist, and astronomer. He is reportedly one of the first persons to understand the potential of photography as a powerful scientific and geodesy tool. As early as 1839 (the same year the daguerreotype was presented to the public), in one of his addresses¹ championing this new technology he stated
"(...) et les images photographiques étant soumises dans leur formation aux règles de la géométrie, permettront, à l'aide d'un petit nombre de données, de remonter aux dimensions exactes des parties les pius élevées, les plus inaccessibles des édifices."
which can be freely translated to something like
"(...) and the photographic images being subjected in their formation to the rules of geometry, will allow, with the aid of a small amount of data, to reconstruct the exact dimensions of the most elevated, the most inaccessible parts of the buildings."
AragoJ is a user-friendly Java application to help in the work-flow of single-camera, close-range photogrammetry, a technique that was developed in great part due to François Arago's vision.
More about François Arago can be found in Wikipedia and the reading of his own account of his unbelievable early life is highly recommended either in the original French or translated to English.
This wiki is meant to help using AragoJ. It is divided in several sections that should allow anyone to understand the function of the different tools and modules in AragoJ. It will be updated frequently as new utilities are added to the program.
A printable pdf version of this Manual is also available.
