On the shadow areas in X Profile, the value of shadow shows less than 24. In this example image, threshold value “24” of shadow is selected as the initial value.

HINT: How to leave target (outcrop) areas and mask shadow of cloud areas. The figure below shows ROI (red color) on Band 3 image (left) and X profile of Band 3 image on the red horizontal line (right). This is the result in case of threshold value “24”. In this case, target areas are masked because target areas have almost same reflectance value as shadow of cloud areas. It is difficult to separate them only using threshold value “24”. To separate each area, the following procedure is used. - Click “New Region” box on the “#2 ROI Tool” menu bar. - Click “ROI Type” and select and click “Polygon” and Multi Part: off - Click “ROI Type” and select and click “Multi Part: off” - Click “Image” circle shown in upper part of the “#2 ROI Tool” window. - Move to “ Image” of #2 Band 3 display and enclose shadow of cloud with polygon (figure below). To create polygon Trace the border of area to be masked on Image by mouse. Click left mouse button to put point. Put points as enclosing shadow of cloud. After finishing trace, click right mouse button twice to fix. To cancel, click right mouse button once and small diamond appears then click middle mouse button. To remove the polygon after fixing, click middle mouse button on the polygon you want to remove. Repeat this procedure to all areas to be masked.

This graph is made from eigenvector data of PC band in the list of "Stats File" window. Pay attention to each eigenvector of PC band. How much does each ASTER band contribute to each eigenvector of PC band? Consider what the image of each PC band shows geologically in comparison with geological maps or geological information. Create meaning of PC band image and select effective PC bands for creation of band composite image finally to do geological classification and detection of target geology. In this case, As PC Band1 eigenvector consists of almost same contribution value of each ASTER band, PC Band1 shows albedo. PC Band1 is out of selection. Generally, noise on the image increases in larger number of PC Band. Noisy PC Band8 and PC Band9 are out of selection. In this case, the rest of PC bands (PC Band2, 3, 4, 5, 6, 7) are selected for creation of PC band composite image. In the graph, eigenvector component of PC band2 shows positive value in VNIR range and negative value in SWIR range. Eigenvector component of PC band4 shows negative value in the middle of bands. By trial and error, create PC band composite images and select the best image to express geological characters of the survey area.



125

In this case, PC Band2, Band3, Band4 are selected for creation of PC band composite image. - A color band composite image (RGB=PC Band4,Band2,Band3) of ASTER PCA data is created.



126

Comparison of the geological map and the PC band composite image (RGB=PC Band4,Band2,Band3) The distribution of redish color on the PC band composite image corresponds to reddish color on the geological map. The distribution of yellow color and water blue color on the PC band composite image correspond to greenish and yellowish color on the geological map respectively. Grey color on the PC band composite image shows no analyzed area because of the vegetation. On the geological map, reddish color, greenish and yellowish color show Xsy(Perthite-gneiss grading into perthosite), Xs’(Banded gneiss) and Xt(Plagioclase-granulite) respectively.

Extraction of Lineament by using PALSAR Image A lineament is a linear feature in a landscape which is an expression of an underlying geological structure such as a fault. Generally a lineament represents a fault-aligned valley, a series of fault or fold-aligned hills, a straight coastline or a combination of these features. Fracture zones, shear zones and igneous intrusions such as dykes can also give rise to lineaments. Lineaments are often apparent in geological or topographic maps and can appear obvious on aerial or satellite photographs.
