A digital image restitution and mensuration software package was developed and installed in a geographic information system. Mapping is performed by monoscopic digitization in the image display screen. Three of the four image restitution schemes employ a rigorous mathematical model for generating the object space coordinates, while the fourth one provides a close approximation. The primary application of this mapping tool is in map revision and natural resource inventory mapping. It is suitable for those with no photogrammetric experience.
