1:250,000 Groundwater Flow System layer converted to a grid based on DEM25
This layer details the boundaries of the Salinity Management Plans. These boundaries define the administrative extent for each Salinity Management Plan Not all areas of the state are covered by Salinity Management Plans.
This dataset has been created to show public land along the coastal strip. It is based on PLM100 data, but has had additional parcels added to represent foreshore reserves which arent shown in PLM100 or are not accurately mapped. The attribute fields have all been checked and validated, so now show more uptodate names, recommendations, management categories and managers. Compiled for coastal mapping and a more accurate representation of coastal reserves.
Estimated long-term mean annual radiation interpolated to a 20m grid cell using the DEM20 layer and the ANUCLIM software.
This layer delineates broad agricultural land uses in Victoria. LUSE250_1991 was created by manually interpreting 1991 LANDSAT TM satellite data and incorporating forest cover boundaries from FORCOV500-87. The land use boundaries have been registered to 1:500,000 topographic features. (not current - see revised LANDUSE250)
This layer is not current (see LBPZONE25) but it maintained for historical purposes. A zoning of forest into suitability of habitat for Leadbeater's Possum (LBP) (Gymnobelideus leadbeateri), based on a visual interpretaion of aerial photographs to identify certain density classes of stags, followed by refinement based on ground survey.
This layer contains polygons showing tree cover change as defined by woody vegetation greater than 2 metres in height and with a crown cover (foliar density) greater than 10 percent. Tree cover is mapped down to a minimum area of one hectare. Attributes outlining the causes of tree cover change are assigned for areas greater than 1 hectare. This layer was derived from LANDSAT TM digital data.
This land use map has been prepared under the NLWRA (NHT) project of Theme 5 (Land use change, productivity and Sustainability) for Gippsland. The map refers to the year 1996-97 and is based on 4 sources of information: (1) Resource data sets of Victoria held at CGDL, DNRE, (2) Satellite imagery, (3) ABS Agricultural Statistics, and (4) Field information. The land use classification scheme that has been followed in this map was developed at a workshop convened by BRS and contributed by Commonwealth and State staff in May 1999. The scheme is a modification of a classification proposed by Baxter and Russell in 1994 for the Murray Darling Basin. The classification is hierarchical in nature, identifying primary, secondary, and tertiary levels. The five primary levels show a hierarchy in terms of human intervention in natural environment.
Part of the Vicmap Crown Land Tenure dataset series - superseded by GOV_ROAD_POLYGON. This dataset plays a key role in the management of Victoria's Crown land. It is being created (June 2003 - Feb 2004) from migrating LCMP layers into the Vicmap structure. At this stage it does not cover Metropolitan Melbourne. The layer provides information about Crown Roads. The dataset is continually maintained, obtaining maintenance from authoritative sources within State Government. GOV_ROAD_POLYGON is a polygon layer depicting Government Roads including roads as laid out on Parish Plans & proclaimed as Road in Government Gazettes.
Estimated long-term mean monthly daily maximum temperature interpolated to a 500m grid cell using the DEM250 layer and the ESOCLIM software.
