Lineaments Extraction and density Mapping using ArcGIS @GIS Tutorial
The lineament density was defined as the total length of all the recorded lineaments divided by the area under consideration (Edet et al., 1998). Lineament density of an area can indirectly reveal the groundwater potential, since the presence of lineaments usually denotes a permeable zone. Areas with high lineament density are good for groundwater potential zones (Haridas et al., 1998).
Lineaments are linear features which provide information about the underlying geological structure. Lineament is one of the most important features showing subsurface elements or structural weakness such as faults and is usually extracted by visual analysis of enhanced image data.
