Comparison of Landsat digital enhancement techniques for lineament detection
The synoptic view of local and regional lineament patterns by Landsat is a useful mapping technique in areas considered to be well mapped as well as in poorly mapped areas. Image enhancement of digital Landsat data increases contrast and sharpness between geologic features and improves the recognition of subtle differences. Five enhancement techniques were applied to Landsat digital data for lineament detection for a portion of the structure in southeastern Oklahoma, specifically a 169 mi/sup 2/ area centered in the Ouachita Mountains. Of the five enhancement techniques evaluated (1) mean value of all four bands, (2) principal components, (3) band ratio, (4) histogram equalization, and (5) high-pass filter, the principal components analysis identified the greatest number of lineaments and the greatest total length of lineaments. All five techniques identified a significant amount of unique lineaments which were not found by any other technique; they agreed, however, in terms of the directions in which the lineaments were oriented. The unique lineaments identified by each technique were combined through a composite process to yield a lineament interpretation which exceeded the detection capability of the principal components enhancement.
