Launceston - potential rockfall hazard zone polygons

공공데이터포털

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.

Launceston geomorphology - structural surface dip direction and slope points

공공데이터포털

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.

Launceston geomorphology - depositional polygons

공공데이터포털

This dataset (geomorphology_poly_depositional.shp) contains polygons delineating depositional geomorphic features of the area covered by the Tasmanian Landslide Hazard Map Series: Launceston. The data has been generated through a combination of simplification of surficial deposits shown in the seamless 1:25 000 geology data held by MRT and aerial photography interpretation. The shapefile was created using ArcGIS software.

Geomorphological polygons of Glenorchy

공공데이터포털

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.

Geological polygons of Glenorchy

공공데이터포털

This layer shows geological polygons of the Glenorchy Area as part of the Tasmanian Landslide Hazard Map Series, 2005.

Launceston geology - dolerite talus polygons

공공데이터포털

This dataset (geology_doleritetalus_poly.shp) contains polygons delineating areas of dolerite talus in the Launceston area as part of the Tasmanian Landslide Hazard Map Series. The data within this dataset is extracted directly from the geological polylgon dataset based on a query on the field SYMBOL. This unit is depicted on the rockfall map to indicate areas that could be rock fall source zones if disturbed.
