Measurability and Interpretability of Image Detail 
ng Three specific areas of traditional interest to photogrammetrists 
are being investigated: 1) variances in x and y coordinate measure- 
| ments performed with photogrammetric equipment; 2) systematic errors 
associated with pointing to image detail; and 3) the influence of image 
quality on the interpretability of detail. It is hoped that relation- 
ships between these tasks and factors such as MTF, film granularity, 
constrast, image scale and optical viewing magnification can be 
developed to provide a quantitative basis for comparisons of systems 
een utilized for photogrammetric applications. If satisfactory relation- 
(e ships between image quality parameters and the measurability and inter- 
pretability of detail can be established, a concentrated effort will be 
required to educate photogrammetrists on how to incorporate this 
zd information into their operations.
