Abstract
Experiments of visual extaction of lineaments based on three types of color composite imageries of Landsat MSS covering a geologically complicated part of Korean Peninsula were made.
The first type of the imageries was false color made from the combination of MSS Band-4, -5 and -7 while that of the second type was false color made from a combination of Band-5 and -7 in which Band-5 transparency was used twice, i. e. it was used instead of Band-4 in the regular type of the false color imagery. It was found that the score of extracting geological information obtained from the two types of imageries was almost same leading to a conclusion that the so called 2-band false color imagery is good enough for practical use in geological study.
Based on the result of the experiments, a false color mosaic of Korean Peninsula was first made using multitemporal 240 and 70 mm transparencies
as the basic data for the geological study of Korean Peninsula. Density adjustment was performed for different generation transparencies taking the second generation negative transparency as a standard. In the process of color composition, Kodak Wratten Filter 98(Blue) and 99(Green) were used for Band-5 and Kodak Wratten 25(Red) was used for Band-7 transparencies respectively. It is found that the false color mosaic thus made is useful to obtain geological features especially those of lineament.
