Development of a Method to Detect Geologic Faults and Other Linear Features from LANDSAT Images

摘要

Methods of detecting geologic faults and other linear features by means of processed LANDSAT satellite images have gained prominence during the past several years. There have been numerous programs written to pick these 'lineaments,' but they have been almost universally tailored to large computers. This Bureau of Mines report describes a detection method developed for use with a minicomputer. The method comprises a suite of programs that scans an image for all 'potential' lineaments. From this partially analyzed data, the final lineaments are picked by another routine. The method was field tested in an area of south-central Wyoming, and results indicated good agreement between computer-picked lineaments and ground features. The method is relatively new but promises to be a viable reconnaissance technique for the mining industry in geologic structural analysis.
