Arizona Lineaments derived from 10m DEM Multi-Directional Hillshade

This dataset contains lineament features automatically extracted using the LINE algorithm in Catalyst (PCI Geomatica) Focus Module from a 10m resolution Multi-Directional Hillshade (MDHS) derived from a 1/3 arcsecond DEM of Arizona. The lineaments were extracted from the MDHS using a low pass filter to smooth noise, and then processed with the LINE algorithm. The resulting lineaments were cleaned to remove artificial features, and a lineament density raster was created.

Lineaments—linear or curvilinear surface features—often correspond to underlying faults, fractures, or lithologic boundaries, and are important indicators of secondary permeability. As such, lineament density has been widely used to identify zones of enhanced infiltration and potential groundwater recharge, particularly in karst and fractured-rock terrains.

This dataset supports integrated hydrogeologic analysis, especially in regions lacking detailed subsurface data, by providing a proxy for structural controls on groundwater movement.
