Abstract:

In planning remote sensing missions with multiband photography in the visible and near infrared regions, few investigators have ready access to the spectral information needed to choose the appropriate filter combinations. If the mission is aimed toward mapping a specific type of target the optimum choice of filters will depend not only on this targets spectral characteristics but also on the backgrounds spectral properties. However, these data are not generally available for target-background combinations. This paper describes a technique whereby one may inexpensively pre-test to determine the optimum filter combinations and the feasibility of such a multiband mission. The test provides multispectral reflectivity curves not only for the targets or categories to be identified but also for those backgrounds against which they are usually encountered. The budgetary requirement for the test involves only about two hundred dollars for equipment. This cost is an order of magnitude less than the least expensive spectrometer and yet the results have been shown to be comparable. The potential accuracy of this technique is plus or minus 1.5 reflectance. Author
