This dataset (geomorphology_poly_structural.shp) contains polygons delineating structural aspects of the geomorphology in the area covered by the Tasmanian Landslide Hazard Map Series: Launceston. The data has been generated by aerial photography interpretation. The shapefile has been generated using ArcGIS software.

This dataset (geomorphology_point_dips.shp) contains data in point form showing the dip direction and slope for structural slope surfaces identified within the area of the Tasmanian Landslide Hazard Map Series: Launceston. The surfaces themselves are delinated as polygons within the accompanying Launceston geomorphology - structural polygons dataset (geomorphology_polygon_structural.shp). This point shapefile has been generated using ArcGIS software.

This dataset (geomorphology_line_slopebreak.shp) contains polylines delineating breaks of slope associated with escarpments and terrace edges in the area covered by the Tasmanian Landslide Hazard Map Series: Launceston. The shapefile has been produced using ArcGIS. The data has been generated through on-screen digitising of features identified by aerial photography interpretation.

This dataset (geomorphology_line_faults.shp) is a shapefile generated using ArcGIS containing polylines delineating faults and lineaments for the area covered by the Tasmanian Landslide Hazard Map Series: Launceston. Most of the data comes directly from the 1:25 000 seamless geology data held by Mineral Resources Tasmania and has been edited to only contain faults and lineaments within the area of interest. Faults with no geomorphic implications have been removed. The additional features are based on interpretation of aerial photography.

This dataset (geomorphology_point_knickpoints.shp) contains points identifying the location of significant knickpoints within in the area covered by the Tasmanian Landslide Hazard Map Series: Launceston. The data has been generated by aerial photography interpretation and the shape file created using ArcGIS software.

This layer shows geomorphological polygons of the Hobart Area as part of the Tasmanian Landslide Hazard Map Series, 2005. Features consist of surficial units identified in the 1:25 000 geology map of Tasmania and reclassified based on depositional environment. The features provide an indication of surficial units that were thick enough/ important enough to be depicted in the geological mapping process.

This layer shows geomorphological polygons of the Glenorchy Area as part of the Tasmanian Landslide Hazard Map Series, 2005. Features consist of surficial units identified in the 1:25 000 geology map of Tasmania and reclassified based on depositional environment. The features provide an indication of surficial units that were thick enough/ important enough to be depicted in the geological mapping process.

This layer shows landslide hazard zones of the area covered by the Tasmanian Landslide Hazard Map Series: Launceston. This data was created through a grid based modelling process and converted to shapefiles for distribution. This grid based data has been converted to a shapefile fro distribution. There is consequently, some pixellisation of the polygon boundaries.

This layer shows potential rockfall hazard zones of the area covered by the Tasmanian Landslide Hazard Map Series: Launceston. This data was created through a grid based modelling process and converted to shapefiles for distribution. The grid based data has been converted to a shapefile for distributions. There is some consequent pixellisation of the polygon boundaries.

Landslide component polygons of landslide features mapped across Tasmania, with summary landslide data derived from the Geohazards (Landslide) Database, Tasmanian Information on Geoscience and Exploration Resources (TIGER) system; administered by Mineral Resources Tasmania (MRT). A landslide is defined as a downslope movement of a mass of rock, debris or earth by a variety of failure modes (slide, flow, spread, fall, topple, or combinations thereof) â but excludes subsidence (such as karst areas). The summary landslide data includes: the landslide ID (database reference), the landslide component (polygon) mapped, the landslide name, the locality, the feature type (type of landslide entity mapped), the landslide classification, the activity state (âRecent or Activeâ or âActivity Unknownâ), the earliest known activity, related reports (largely MRT reports), related MRT plans.
