A method for computer extraction of geological lineaments from LANDSAT images is presented. The variance thresholded map of each image is separated into eight gradient direction maps, where basic linear segments are determined each of which is based on the principal eigen vector of a cluster of pixels whose gradient direction is orthogonal to its orientation. A special linking algorithm operate...

Aeromagnetic gradient data have higher horizontal resolution on shallow sources, a magnetic anomaly that can better reflect the features of deeper sources. Therefore, we used joint survey aeromagnetic and to obtain distribution sources with different depths. In this paper, propose an intersection constraint weighting (ICW) method based for original anomalies inconsistent high-low variation char...

Abstract Remote sensing often used in geothermal exploration because it was considered has many advantages. The aim of this research is to extract and analyze the lineament density Libungo area based on a Digital Elevation Model (DEM). Lineament obtained from (DEM) satellite image data downloaded Geospatial Information Agency (BIG) page. processing uses Geomatica aplication automatically. Extra...

Digital filters are used for identification, prediction, and modeling of hidden objects in dynamic systems. These Gaussian filter with power spectrum depth estimation, edge detection the as well constructed 2-D geomagnetic objects. In this paper, digital results obtained by MATLAB software. Magnetometer instrument is to collect aeromagnetic data Aeromagnetic collected from Aswan area Egypt. cod...
