TASMANIAN SHORELINE GEOMORPHIC TYPES DIGITAL LINE MAP VERSION 4.0 (2006)

The Tasmanian Shoreline Geomorphic Types Line Map is a digital line map encoding a range of geomorphic and related attributes describing the landform types comprising the coast of Tasmania and its major islands including the Bass Strait islands and most minor islands larger than about 1 hectare. The original (version 1) of the map was compiled between July 1999 and July 2000 by Chris Sharples and Richard Mount (then of DPIWE), for the Oil Spill Response Atlas and the Australian Coastal Atlas. Subsequent ground-truthing and other data sources have been used by Chris Sharples to refine and update parts of the map during several subsequent projects funded from a range of sources, and it is now (2006) in its 4th version. A data dictionary accompanying the data set and available from the custodian gives a detailed explanation of attributes and other information about the map.

The map comprises a line representing the High Water Mark, mapped at 1:25,000 scale and geo-referenced to the GDA94 datum, which has been manually split into over 12,000 segments, each representing a geomorphically distinct coastline section. Each segment is tagged with a range of attributes describing the geomorphology and geology of that coastal section. Including islands, 6472 kilometres of Tasmanian coastline has been classified in this way within version 4.0. The geomorphic data is presented in a simple (yet detailed) descriptive format which is applicable to a wide range of coastal management and research purposes.
