This paper describes experience at ACIC obtained with the AP-2 Plotter. It discusses the basic concepts upon which the AP-2 Plotter operates, some key tests performed, and problems associated with its introduction into a mapping organization and evaluates the plotter with respect to contemporary instrumentation. Emphasis in technical discussion is placed upon the capability of the plotter to remove systematic distortions arising from random and non-random sources. This instrument represents a great advancement in photogrammetric instrumentation, but in its present form should not be expected to reduce operational time significantly in bridging and compilation operations. The AP-2 allows more complete exploitation of photogrammetric materials, but because of its complexity and increased requirements for advanced personnel training it will not be easy for most organizations to incorporate it in their line operations.
