Estimation of lineaments in catchment scale, using satellite image
General geography. Description and travel
In order to confirm the automatic extraction of lineament by satellite image analysis, we analyzed a Landsat TM image in Chugoku region of western Japan by image processing according to Kageyama et al, 2002. The results are summarized as follows, lineaments were extracted and they were similar to the active fault lines and geological boundaries in a scale of 1/500,000. However, lineaments were not drawn enough in a scale of 1/50,000. This result suggests the utility to the regional groundwater flow and water resource analysis and regional geological and topographical analysis. However, we need to upgrade the analysis and use image to apply to disaster sciences and hillslope hydrology.
