Lineaments interpreted from Topography

dataset: LINEAMENTS_TOPO
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.

Statement
Dataset Source: A 100m resolution Digital Terrain Model (DTM), resampled from the nominal state-wide 20m x 20m raster dataset, was the key input dataset. Lineament analysis was undertaken using ER Mapper and the topographic dataset emphasising the interpretation of structures cross-cutting the bedrock lithology grain. This is in difference to the bedrock structural interpretation completed by the (former) Department of Primary Industries (DPI) which largely defined key lineaments parallel to the bedrock lithology grain. Linear structures evident to a greater or lesser extent from the east, north, north-east, north-west and overhead vertical sun angles were interpreted. For this study, because of the importance of NNW trending bedrock lithology grain and ENE (particularly) and WNW (to a lesser extent) trending cross-cutting structures, the sun-angles chosen for geophysical image display tendED to be NNW to NNE and high in the sky (+70 degrees).
