Lineament extraction using remote sensing data mid Iraq

Abstract EN

Lineaments are considered evidence for the existence of subsurface structures, so it was in this research work on the geological interpretation of the study area during the extraction of these lineaments.

Mosaic have been work of three satellite of the panchromatic band (8) for Landsat-8 for the region confined between longitudes 44° 35' 22.27" East to 44° 59' 3.97" East and latitudes 32° 48' 57.49" North to 34° 6' 27.27" North and area estimated at (18659.45 km2 ).

The lineament considered very important indicator to determine the general and local tectonic trends and areas of fractures in rocks.

Four programs have been used in the work are (ENVI5.1, PCI-Geomatica 2014, ArcGIS10.2.2 and Rockwork16).

It has also been three geospatial applications which analyzes (height, density and direction) in order to estimate lineaments.

Used manual and automatic methods to extract lineaments.

When using the manual method found that the lineaments be greatest, this difference between two methods is due to use of Sobel operator to enhance the digital image in the manual way .Extracted lineaments of both methods was more density when the folds and local fractures areas and concentrated towards the NW- SE.
