Abstract : Landsat-3 Multispectral Scanner (MSS) digital image data of the Ha'il region of northern Saudi Arabia were subjected to edge-enhancement processing with multiple original data add-back options to highlight small stands of phreatophytic vegetation--an important ground-water indicator. On the basis of a rating detectability scheme for 16 vegetation targets, an edge-enhanced MSS 4, 5, 7 image with 30 percent add-back contained the highest level of vegetation detail. The primary reason for this was that diminution in original data add-back reduced radiometric or albedo masking effects. (Author)
