ABSTRACT:
The improvement and development of Informatics have allowed the strength of Digital Photogrametry paving the way to the future of the
subject with effectiveness, speed, simplicity and low costs.
In this moment, the automatization of the photogrammetric processes with cartographic ends in Cuba is developed responding to a general
strategy that comprises different stages such as the conversion of the analogue systems of restitution to analogue — digital systems, the
partial introduction of technologies of Digital Photogrammetry, as well as the development and improvement of the Digital
Photogrammetry technologies about professional platforms.
The current status of this branch in Cuba stands in the Digital Photogrammetric Stations, which are addressed not only to create digital
maps but also to be in function of the processes of cartographic updating, terrain 3-D modeling among others, for which different
photogrammetric platforms of work are integrated through files of interchange.
Different technical and technological elements related with digital photogrammetry as well as their integration with various applications
developed within Geomatics (DEM, CAD, GIS, etc.) are presented. It is explained the development of Cuba in the field comprising the
interest of economy, health and physical planning among others. Besides, it is assessed the strategy followed for the generalization of the
Digital Photogrammetry in Cuba.
INTRODUCTION: One of the main trends in current cartography is the relationship
between data acquisition and the treatment of geoinformation.
The evolution of Photogrammetry in Cuba as a technological
alternative for the creation of topographic and thematic maps is The automation in cartography offers a great deal of advantages
presented in this work. It deals with the analogue technologies as:
