New generations of advanced remote sensing data have been used by Earth scientists over last decades. This study presents the applicability of recently launched Landsat8 and SRTM digital elevation model data for lithology and structure mapping. Processing of multispectral medium resolution of landsat8 and SRTM digital elevation model data were used for detection and mapping lithology and structures. The data have been processed and interpreted with the production of lithologic and structural map, at a scale of 1:100,000. Processed Image results indicate that lithologic features and their textu...
New generations of advanced remote sensing data have been used by Earth scientists over last decades. This study presents the applicability of recently launched Landsat8 and SRTM digital elevation model data for lithology and structure mapping. Processing of multispectral medium resolution of landsat8 and SRTM digital elevation model data were used for detection and mapping lithology and structures. The data have been processed and interpreted with the production of lithologic and structural map, at a scale of 1:100,000. Processed Image results indicate that lithologic features and their textural characteristics are easily identified by coastal/aerosol, visible, near-infrared and short wave infrared (1 to7) bands with resolution merge of band 8(pan) bands. Spatial enhancement of landsat8 data using convolution filters (spatial domain of the image) and digital elevation model (DEM) extracted from the Shuttle Radar Topographic Mission (SRTM) have been used for structures extraction. Hill-shading techniques are applied to SRTM DEM's to enhance terrain perspective views and to extract morphologically defined structures.
