ACQUISITION OF 3D DATA IN GIS ENVIRONMENT

The process of cartographic production of M888 military map of the Army Geographic Institute (IGeoE) at scale 1:25 000, consists in a high complexity sequence of steps which are usually discussed separately. Being the acquisition of spatial information from stereoscopic pairs the first of these steps, it was precisely where has been introduced the concept of using Geographic Information Systems (GIS) to produce spatial data. Due to the implications that this change represents for a system that has over the years being adjusted and tuned, given the high investment so that it becomes feasible it is necessary for its implementation be done in a phased manner. Therefore, we intend to approach with this article in brief the process of adapting the methods of acquiring stereoscopic environment, using GIS, emphasizing the type and format of data that are obtained, and the various processes that aim to make this information as consistent as possible with the existing reality on the ground.
