Lineaments interpreted from Topography

Brief description

This dataset comprises lineaments interpreted from the State's 100m x 100m resolution Digital Terrain Model (DTM). The interpretation has been completed on a regional or sub-regional scale using geophysical remote sensing techniques and has confirmed that topography is a key structural analysis dataset. This is because it frequently shows strong evidence of the recent reactivation of older fault structures.

The analysis identified a number of key topography lineament directions across the state:

ENE-WSW: the dominant set of long and persistent linear features;
WNW-ESE: the next most obvious interpreted topographic lineament dataset;
N-S to NNE-SSW: trends mostly associated with known terrane boundaries.

Generally, only lineaments which have not been published in existing datasets developed by the former Department of Primary Industries (DPI) have been identified in this study.

The dataset was compiled by GHD to inform the report 'Potential Influences of Geological Structures on Groundwater Flow Systems' for DEPI's Secure Allocation Future Entitlements (SAFE) Project.
