The land systems of Victoria, as described and delineated by Rowan in 1989, provide a statewide coverage of land type that are applicable to a wide range of land resource management and planning programs. This dataset consolidates a broad range of land resource information drawn from an uneven base to provide a consistent, if limited, coverage of the lands of Victoria. The explicit links with the original sources of data have been retained. The data set was developed from a range of studies of varying methologies and intensities over some forty years.
The reliability of the information varies across regions accordingly.

Abstract:
The land systems of Victoria, as described and delineated by Rowan in 1989, provide a statewide coverage of land type that are applicable to a wide range of land resource management and planning programs. This dataset consolidates a broad range of land resource information drawn from an uneven base to provide a consistent, if limited, coverage of the lands of Victoria. The explicit links with the original sources of data have been retained. The data set was developed from a range of studies of varying methologies and intensities over some forty years.
The reliability of the information varies across regions accordingly.

Purpose:
This data set assists with state and regional planning to define the spatial variation of land according to the parameters of geomorphology, lithology, landform and climate, with dependent variables of soil and vegetation types. Other interpreted data tagged to the land systems includes the hazard potential, ie. inherent susceptibility to various forms of land degradation, and the 'potential productivity'.
The maps and land system descriptions are drawn from an uneven database of some 28 individual studies of the land and additional unpublished data, with varying levels of detail and reliability. The land system descriptions are presented as a single line that masks the considerable variation in each land system -- each land system is treated as essentially a single point entity, when in reality it is a complex of land types with a known range of variation. While this is appropriate for some purposes, it is not suitable for all uses, and should be used with care. Potential users not familiar with the land system concept are encouraged to contact the custodian for advice and assistance.
Interpretations are of the inherent susceptibility of the land to degradation and do not adequately represent hazards (which involves considerations of land use) which will be of interest to most users.
Rowan's initial report, paper maps and transparencies are now considerably out of date following extensive error checking and subsequent revision. While the initial report was never formally released, the revised and expanded Edition 2 is in an advanced stage of preparation and should be released in 1994/95.

Relationship to other Datasets: This layer forms a strong relationship with LSYS100 which describes landsystems in more detail. See the previous section for further details.
Current Design Issues: The land system code is derived from Geomorphic Unit (GMU), Landform, Lithology and Climate.
Future Design Issues: Some of the source information was prepared at a scale of 1:100 000; some of this has been entered into the Department's GIS. The remainder of the information is at a range of scales and is unlikely to be entered into the GIS. New information will be assembled at a scale of 1:100 000 and will be entered into the GIS. Explicit linkages will be established between the two layers as appropriate.<P>Explicit linkages will also be created between layers at larger scales (1:25 000) and point data layers.

The original data set was supported by an unpublished report Land Systems of Victoria, prepared by Jim Rowan for the Land Conservation Council and the Land Protection Branch of DCNR. The revise dataset will be supported by a revised Departmental publication, Land Systems of Victoria - - Edition 2, by Rowan, Russell and Ransome. This report is in preparation and should be released in 1994/95.
