Quantitative evaluation of lineament extraction potential using TM data

Abstract

Lineament and geological information extraction from Remote Sensing data is important for the analysis of natural resources exploration. It is understand that lineaments are mostly reflecting the fractures of subsurface. These fractures sometimes work for the migration and stratigraphic trap of petroleum from deeper portion of source rocks.
From this point of view, In this paper, the quantitative evaluation using extracted lineaments pattern from Landsat TM has been studied. Two Laplacian types of edge enhancement processing were applied to compare the effect of enhancement. Lineaments were extracted by two interpretors from 9 processed images, and those extracted lineaments were analyzed statistically.
As the results, those lineamets were remarkably appeared defferently depending upon the features of each studied areas and edge enhancement parameters. Maximum cumlative length of extracted lineaments were nominaly appeared from simply enhanced images. Medium length of lineaments were also appeared from enhanced images.
