Abstract

This dataset maps the geomorphic habitat environments (facies) for 52 Victorian coastal waterways. The classification system contains 12 easily identifiable and representative environments: Barrier/back-barrier, Bedrock, Central Basin, Channel, Coral, Flood- and Ebb-tide Delta, Fluvial (bay-head) Delta, Intertidal Flats, Mangrove, Rocky Reef, Saltmarsh/Saltflat, Tidal Sand Banks (and Unassigned). These types represent habitats found across all coastal systems in Australia. Most of the 52 coastal waterways have a "Modified" environmental condition (as opposed to "Near Pristine"), according to the National Land and Water Resources Audit definition.

Lineage

Data source: Georeferenced 30 metre resolution Landsat TM 5 images. Georeferencing performed using image processing software (ER Mapper), with 10-15 ground control points per image, against 1:250 000 scale topographic maps. Aerial photographs ranging in scale from 1:10 000 to 1:80 000. Interpretation: For individual coastal waterways, the Landsat images were printed at an appropriate scale, ranging from 1:15 000 to 1:50 000. Boundaries of geomorphic habitats (facies) were mapped by hand over these printed images, with the assistance of aerial photographs. Where Landsat imagery was unavailable, digital images of 1:100 000 topographic maps were used. Digital capture: Hand drawn interpretations digitised on-screen over Landsat imagery, using ER Mapper software. The scale at which each coastal waterway was digitised was no greater than 1:5 000, with a window size of 650x650 pixels. The projection was Transverse Mercator and the datum AGD66. ER Mapper vector files converted to AutoCAD dxf files and then to ArcInfo coverages (one coverage for each coastal waterway), and polygons attributed with geomorphic habitat type. Attribution checked against the original interpretation. Logical consistency checks performed on all coverages, and the projection and datum converted to Geographic, GDA 94. Coverages merged into a single shape file, using the Geoprocessing Wizard in ArcView 3.2.
