Project LEFA (http://lefa.geologov.net) is GUI Matlab script package created
for satellite image decomposition for Earth sciences implications. Fracture
analysis is often being used for geological mapping, detecting natural hazards
and prospecting of mineral resources. Achievements in computer image
processing and digital mapping made possible human independent feature
LEFA contains free of charge set of Matlab scripts, which allows to:
-Extract lineament features on satellite image (Landsat 7 and 8, SRTM and
some others are supported);
-Compute feature spatial distribution parameters (density and Minkowski
-Create Rose diagram plot of lineaments direction;
- Export features into ESRI shape format to continue work in GIS software.
LEFA uses single window interface for the whole cycle of image processing.
