Land Systems of Victoria at 1:250 000
dataset:
LSYS250
The land systems of Victoria, as described and delineated by Rowan in 1989, provide a statewide coverage of land types that are applicable to a wide range of land resource management and planning programs. These land systems sit within a geomorphological framework developed by Jenkin and Rowan.
This data set 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 methodologies and intensities over some forty years. The reliability of the information varies across regions accordingly.
This edition (3) incorporates new survey material [Shires of West Wimmera, Lowan, West Towong and East Gippsland (east of Snowy River)] as well as changes in the nomenclature with the substitution of broad slope class with relative relief classes (eg. plains, hills, mountains). An addition factor (lithological age) was also added to the key. There is still a link with the Edition 2 version in the main Land Systems table.

Description
- Title
- Land Systems of Victoria at 1:250 000
- Alternate title
- LSYS250
- 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and land system descriptions are drawn from an uneven database of some 28 individual studies of the land and additional unpublished data, with varying levels of detail and reliability.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 unpublished form which has now been modified itself by Edition 3, released in January 2000.
- Credit
- The land system data set was initially constructed by Jim Rowan, based on a geomorphic framework erected by Jeff Jenkin, and using more detailed land resource information derived from some twenty-eight other studies.
- Supplemental Information
- History: Landmark Steps: Provisionally Approved:29 March, 1994 (edition 2) Approved: Implemented:2000 (Edition 3) Last Reviewed: 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, Litholgoical Age and Climate, updated from Edition 2. The landform classes have been changed such that the range of dune landforms have been reduced to two and the broad slope categories (gentle and steep) have been replaced by relative relief classes (plain, rise, low hill, hill, mountain). A number of new lithological categories have been added such as basic volcanics distinguished from volcanics as a whole, as well as metamorphic materials separated out from broader lithological groupings. A new factor for the Statewide code is Lithological Age, which is catagorised in broad terms but provides a framework for more detailed description at a finer scale. 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. New survey data produced at 1:100 000 scale has been incorporated into the new edition (3) Staetwide land systems. These are Shires of West Wimmera, Lowan and (west) Towong as well as East Gipplsland, east of the Snowy River. Further assessment of the suceptibilities to various forms of land degradation will be required in the future as more information becomes available. Explicit linkages will also be created between layers at larger scales (1:25 000) and point data layers. Related Documents: None 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 wase supported by a revised unpublished Departmental publication, Land Systems of Victoria -- Edition 2, by Rowan, Russell and Ransome (1994). The further revised edtion was edited by David Rees , titled Land Systems of Victoria January 2000 Edition 3, Centre for Land Protection Research, Technical report No. 56. http://vro.depi.vic.gov.au/dpi/vro/vrosite.nsf/pages/landform_systems http://vro.depi.vic.gov.au/dpi/vro/vrosite.nsf/pages/landform_land_systems_vic

- Comments
- Precision: 100 m to 1 km. Note: land system boundaries are, in reality, zones of relatively rapid change in relevant land characteristics. Consequently, there is no valid measurement of 'accuracy'. Determination: Estimate
Conceptual Consistency
- Comments
- Only landsystem features are completed.

- Comments
- The layer, as described, is complete and covers all of Victoria. The layer, as described, is complete and covers all of Victoria.
