This layer is part of Vicmap Elevation 10-20 Contours & Relief, a subset of Vicmap Elevation. It contains point features delineating ground type points. Includes: Mountain, Rock Terrestial and Points.

Hydrographs from over 2000 state observation bores were reviewed in order to group bores which have a similar water level trend and are screened in the same aquifer. The groupings of observation bores are referred to as 'suites' and are classified according to the Upper, Middle, Lower and Basement aquifers aligning with the Victorian Aquifer Framework. By applying a statistical technical, a normalised hydrograph was developed for each suite using the observed water levels from all bores within the suite. This hydrograph is representative of the groundwater trend within the suite. A spatial boundary has been created for each suite which encompasses all bores within the suite. The boundaries were manually constructed and cover the extent of the mapped aquifers.

This dataset contains linear geological structure data not included in GPGEOL - this includes anticlines, synclines and trends. At scales larger than 1:120,000 the display is a combination of both 1:100,000 and 1:250,000 geophysical mapping. Recent 1:250,000 geophysical mapping has been of such quality and detail it has been used to supersede older coincident 1:100,000 mapping. This occurs in the following areas: St Arnaud 7524, Dunolly 7624, Charlton 7525, Wedderburn 7625 and part of Ararat 7423 are superseded by St Arnaud SJ54-4. Bendigo 7724, Heathcote 7824 and Nagambie 7924 are superseded by Bendigo SJ55-1. Balmoral 7223, Ararat 7423, Horsham SJ54-3 and St Arnaud SJ54-4 supersede Grampians 7323 where there is overlap. The Ouyen SI54-15 and Horsham SJ54-3 map areas are datasets derived from a combination of Geological Interpretation of Basement Geophysical Features maps and Geological Interpretation of Post-Cratonic Geophysical Features maps performed by Moore, D. H. This data has been collected by the Geological Survey of Victoria. This dataset is accompanied by other datasets representing geological polygons and boundaries, sub-surface geological polygons, miscellaneous lines and metamorphism.

This layer is part of Vicmap Hydro and contains points delineating stuctural features relating to hydrography. Includes; Locks, Wells & Watering Places

The data contains primary geological data, namely regolith-landform units and boundary types separating regolith-landform units. The dataset is part of the geological mapping dataset, which includes datasets representing geological rock units and boundaries, regolith-landform units and boundaries, structural lines, miscellaneous lines and points, miscellaneous polygons, metamorphism and placer deposits. The data have been collected by the Geological Survey of Victoria. Data have been captured in projects covering special interest areas, and have been recorded in the field by hand at scales between 1:10,000 and 1:25,000 then prepared for hard copy printing at a range of scales.

This layer is part of Vicmap Transport and contains point features delineating road infrastructure features. Includes; Bridges, Tunnels, Gates, Cattle Grids, Barrirers, Level Crossings, Roundabouts & Intersections.

This image shows the depth at which temperatures of 150°C can be expected, and was created using temperature data from GeoScience Victoria’s VIMP Report 85 (Driscoll, 2006). Only temperature data from wells deeper than 1000 m was used to construct the image.

Contains mineral, petroleum, coal & groundwater boreholes. Minerals boreholes (and, to a lesser extent, petroleum wells) are actively maintained in the dataset. The custodial role for groundwater and coal boreholes is in the private sector, and these parts of the dataset are not actively maintained. Mineral, petroleum and coal boreholes are updated on an irregular basis: Mineral borehole data are supplied by individual companies usually when their overlaying Exploration Licence expires; Coal borehole data have been updated from GHD Pty Ltd's (formerly GEO-ENG) data. Groundwater boreholes have not been updated since 1990 when the custodial role was given to Sinclair Knight Merz Pty Ltd (SKM) - refer to BORES100. The origin of data varies considerably. Prior to 1980 borehole data was recorded by the Geological Survey of Victoria (GSV) on 1 inch:1 mile plans and hard-copy borehole records. This included data for water boreholes drilled by public and private sector, all boreholes drilled by GSV, petroleum wells, and some private-sector mineral exploration boreholes. In areas where drilling was of particularly high density, locations were recorded on these plans as a single point or as occurring within an outlined area. The parish was traditionally used as the primary classifier for numbering boreholes. Some minor anomalies exist where a borehole and parish boundary may be on one side of a road or the other, or where parish boundaries have been moved. In 1980 the location data was moved to 1:100,000 AMG plans. In the mid-1980s a program of electronic capture commenced. Borehole locations were digitised from the 1:100,000 plans with an accuracy of +/-300m. For the areas of high borehole density where boreholes were plotted on a single point, often only the first ten and last ten were recorded in the database. Boreholes whose parish was known but exact location was unknown were also recorded, but do not have a location. Groundwater boreholes: Extensive hydrological data was originally held by GSV, but these data are now held by SKM. Coal boreholes: Location and lithological data for coal boreholes has been provided by Geo-Eng and the old State Electricity Commission of Victoria. Mineral exploration boreholes: The capture of mineral exploration borehole data from open-file exploration reports commenced in 2001 and will progressively cover the state over a number of years. The data are being captured at an whatever accuracy the source allows, typically between 20 and 250 m. Assay data have been consistently captured. Other downhole data, such as lithology, have not been consistently captured. Tenement information for the small number of private-sector mineral exploration boreholes captured prior to 2001 was lost in the migration from the original VAX database to the current Ingres corporate database. Heavy mineral sand exploration: complete coverage up for data up to April 2002; updates planned for late 2003. Other mineral exploration: coverage as follows - St Arnaud, Charlton, Wedderburn 1:100 000 mapsheets - 31 March, 2001; Dunolly, Rupanyup, Donald, Ararat, Grampians, Willaura 1:100 000 mapsheets - 30 August 2001; Warburton 1:250 000 mapsheet - 30 June 2002 (available mid-2003); Ballarat, Creswick, Skipton, Beaufort 1:100 000 mapsheets - 30 June 2002 (available mid-2003); Bendigo 1:250 000 - 31 October 2002 (available mid-2003) Groundwater data can be obtained at the following site http://www.dse.vic.gov.au/waterdata
