Land Systems of Tasmania
Tasmania was separated into seven regions for the purposes of land system mapping for the period 1978-1989. Non-unique land systems were developed based on six descriptor classes (geological period, geological rock type, rainfall, vegetation, elevation, and differences in dominant soils. Within each land system, land components are described which present examples of soil and vegetation variation across topographic sequences (proportion estimates, but unmapped boundaries). Land Systems are considered to have a nominal scale of 1:100 000. Regions were mapped separately (as below), and amalgamated to form a digital statewide coverage: Land Systems of Tasmania Region 1: King Island. Land Systems of Tasmania Region 2: Flinders Island. Land Systems of Tasmania Region 3: North. Land Systems of Tasmania Region 4: North East Land Systems Survey of Tasmania Region 5: Central Plateau. Land Systems Surveys of Tasmania Region 6: South, East and Midlands Land Systems of Tasmania Region 7: South West.

Dept of Environment, Water and Natural Resources - Land Systems of Southern South Australia (soil landscapes)
공공데이터포털
Land Systems (based upon groupings of Soil Landscape Map Units) are broad and readily recognisable landscape areas defined by particular and distinctive patterns of land use, geology, topography, soils and vegetation within a limited climatic range. A Land System Report is available for each Land System.
Dept of Environment, Water and Natural Resources - Land Types of Southern South Australia (soil landscapes)
공공데이터포털
Land Types define the broad soil grouping and dominant geologic and topographic setting of Soil Landscape Map Units. There are 29 Land Types within 14 geomorphic groups which have been described across southern South Australia. Each Soil Landscape Unit has an assigned Land Type, indicating the dominant nature of the map unit.
LIST Land Tenure
공공데이터포털
The Land Tenure data set contains a representation of the commonly accepted land tenure classifications for Tasmania. Tenure Classifications include Crown Land, Private Land, Local Government and other Statutory Authority Land, Reserved Land, Conservation Covenants, Private Reserves, Permanent Timber Production Zone Land (formerly State Forest). Future Potential Production Forest (FPPF) land is also distinguished where it overlaps Crown and HEC land. This dataset depicts the full extent of classifications and as some or coastal reserve boundaries extend to Low Water Mark, and in some cases include areas of estuary or sea. These classifications generally conform to those represented on the TASMAP Land Tenure Map.
Dept of Environment, Water and Natural Resources - SA Land Cover
공공데이터포털
The South Australian Land Cover Layers 1987- 2015 spatial land cover datasets for 6 time periods (1987-1990, 1990-1995, 1995-2000, 2000-2005, 2005-2010 and 2010-2015). This dataset can be used to inform spatial and temporal (5 year) summaries of the described land cover types for SA. The capture method and general nature of the classes are most useful for landscape and regional scale assessment.
Landsystems
공공데이터포털
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.
Dept of Environment, Water and Natural Resources - Biophysical Regions of Southern South Australia (soil landscapes)
공공데이터포털
Biophysical Regions represent the largest grouping of Soil Landscape Map Units within the SA soil and land mapping hierarchy. These cover broad geographical areas, recognisable at the state-scale (i.e. Eyre peninsula, Yorke Peninsula, Northern, Central, Murray Mallee, Kangaroo Island, South East). Biophysical Regions are differentiated by the general nature of soils, landscapes, geology, native vegetation, climate and land use.
Georegional Classification of West and North West Coastline of Tasmania
공공데이터포털
This data set classifies the actual coastline (ie mean high water mark) in terms of the natural controls on major coastal landform development which are: time, bedrock geology, coastal profile, exposure to climate and geomorphic process. Classifying the coast this way divides the coast into segments known as 'georegions'. Each georegion has its own characteristic assemblage of land forms and is subject to a characteristic suite of environmental influences (processes). This regionalisation provides a predictive tool allowing us to determine the effect of activities or changes on the coastline.Please note that while only the coastline (ie mean high water mark) is depicted the classification represents the intertidal zone and the immediate near and back shore areas as well as the mean high water mark itself.
Tasmanian Geoconservation Database (Natural Values Atlas: Geodiversity)
공공데이터포털
A database of Tasmanian geological, geomorphological (landform), and pedological (soil) sites, features, areas and systems considered to be of significant conservation, scientific or heritage value. Site values are classified according to formative process into 81 types, which are further subdivided by geological age. Multiple values may be attributed to a site. Values are assigned significance on a five level scale ranging from local to global. Significance is determined by an expert panel, the Tasmanian Geoconservation Database Reference Group, which assesses site nominations on behalf of DPIPWE. Site entries contain a text description, statement of significance, an indication of susceptibility to potential threats, management notes and references amongst other details. Spatial data defining site extent is associated and images are progressively being added. The LIST presents a highly abridged version of the full Natural Values Atlas dataset. The LIST version is updated weekly.
Digital Climate Maps of Tasmania (Downscaled CMIP6-era Regional Climate Projection Models)
공공데이터포털
A collection of high-resolution climate grid surfaces for land areas in Tasmania based on CMIP6-era Regional Climate Projection Modelling (via the Australian Climate Service). There are 304 climate products available that delineate temperature and rainfall parameters specific to crop growing requirements that form part of the enterprise suitability mapping program (refer here: https://dpipwe.tas.gov.au/agriculture/investing-in-irrigation/enterprise-suitability-toolkit/enterprise-suitability-maps). Broadly speaking these products include climate risk parameters including frost risk, heat risk and extreme rainfall risk as well as crop related indices including growing degree days and chill hours. Furthermore, mean monthly climate variables including mean monthly maximum/minimum air temperature and rainfall products are also produced. Refer here for dataset inventory: https://nrmdatalibrary.dpipwe.tas.gov.au/FactSheets/WfW/ListMapUserNotes/Inventory_DCM_Tas.pdf CMIP6-era Regional Climate projections were incorporated into the modelling framework to simulate projected climate (according to SSP3-7.0) for years 2030, 2050, 2070 and 2100. These projections were downscaled, and bias corrected to a spatial grid resolution of 30m. Also, note that these outputs relate to the baseline climate maps defined here: https://www.thelist.tas.gov.au/app/content/data/geo-meta-data-record?detailRecordUID=ba62f124-5906-4471-a01c-9b57b6142055 All products can be accessed via Web Map Service: https://spatial.dpipwe.tas.gov.au/naturalassets/Climate/wms Or viewed in the following Web Map application: https://arcg.is/vaHDG
