Previous efforts as part of this program resulted in a new capability for predicting photographic-image optical density contrasts. The product of the efforts was a computerized system model that provides a rigorous, quantitative means of objectively selecting a sensor system and mission profile to enhance the success of a remote sensing data acquisition program. The execution of the model requires computer facilities and specialized personnel. A graphical form of the model was developed to provide a simple planning tool that can be applied by users having a wide range of backgrounds and without computer facilities. This report presents a nomogram for predicting optical density contrasts on aerial photographs. The concept and formulation of the nomogram are discussed and an example of its application presented. The accuracy of the nomogram with respect to the computer program from which it was derived is also evaluated. Author
