| Summary |
"The Earth Resources Technology Satellite (ERTS) program has supplied the scientist with high resolution multispectral imagery of a large portion or the earth. Photographic and electronic methods of image enhancement are not universally available to those who might profit from such endeavors. Diazo products were found to be satisfactory for creation of false color enhancement of ERTS multispectral data. The purpose of the enhancement was to make the Diazochrome composite comparable to more sophisticated methods for the purpose of interpretation. The basis of the enhancement was the standard false color infrared composite, with negative and positive Diazochrome masks to enhance selected terrain features. Major advantages of the enhancement were 1) color renditions were similar to those found on a false color infrared composite, 2) the enhancement process was repeatable, 3) the greater contrast between terrain objects improved interpretation. Interpretability of the enhancement was shown to be restricted by the small scale of the ERTS imagery. Processing of Diazochrome is simple and requires no darkroom. The high contrast, inherent with the Diazochrome film are not suited for continuous tone reproduction without use ot· some enhancement technique"--Abstract, leaf ii. |
