| Abstract/Contents: | Suggests that digital imaging may "enable golf course maintenance crews to detect and treat trouble spots long before they reach critical stages of damage." States that "studies at New Mexico State University and the University of Arkansas show that digital imaging analysis and remote sensing instruments will be able [to] detect stress to turf that includes disease and pest pressure, nutrient deficiencies, salinity levels and precursors of drought." Suggests that "the challenge researchers...face is how long it will take to work out the software bugs and make the cost of the necessary measuring equipment affordable for the average golf course." Explains how digital imaging works, stating that it "uses a computer to inspect and analyze more than 1 million pixels of information contained in a typical, high-resolution digital image. Researchers run digital images of test plots through a software program called SigmaScan, which evaluates each pixel for hue, saturation and brightness of the turf. That information is then compared with the hue, saturation and brightness values that have been established for each species of healthy turf." States that "instead of making an educated guess about the turf, [superintendents] would have objective data on turf conditions on which to base their cultural practices." Describes remote sensing technology, stating that "when turf is under stress, the light reflectance changes at specific wavelengths. Once the specific wavelengths for certain stresses are identified, the equipment will pinpoint the affected areas...the equipment can identify healthy turf, stresses turf, bare soil and weeds." Concludes that "the computer does everything...And even has the ability to calculate the amount of time and the expense that would be required to remedy the identified problems." |
