O.10aInstrumento sencillo para restitución fotogramétrica aproximada.  aRelevamiento: 1996.3 aThe lak of a topographic map or their improper scale is a frequent problem when are accomplished geológical projects. The topographic work through field methods, or the contracting photogramtrics services their accomplishment. they can be costly  in relationship to the scopes of the work that is planned. In  and you case can be convenient to build a small  approximate photogrametric plotter, based on the digital processing of the information. -Even though this basic plotter will not be able to compete in accuracy with the photogrammetric equipment that have the organizations and specialized companies, it can offer reliable topographic map of areas not very vast, of tens to some hundreds of km2, whose accuracy will depend mainly of the quantituy and accuracy on the available checkpoints.Their principal advantages are their ease operation and  under cost,  if is had a mirror stereoscopy with their parallax bar and an PC endowed with a appropriate CAD program. 4aFotogrametría 4aMetodología 0aRestitución 0aRestituidor 4aArtículo2 aInstituto de Geología y Mineríaeeditor0 tRevista del Instituto de Geología y Mineríagvol.11, no.1, p.93-102x0326-9817
