  • This dataset is derived from the Melway directory and contains the pagegrid for the 1:20 000 greater Melbourne maps.

  • This dataset is derived from the Melway directory and contains the pagegrid for the 1:10 000 inner urban maps.

  • Hydrogen facility Locations for Victoria. The locations are a single polygon for the centre of the Hydrogen Facility This dataset is replaced by Renewables and Renewables_point from 30/04/2024.

  • This data is now obsolete, current UDP data is available. This information maps the six industrial nodes identified in metropolitan Melbourne. These are areas where there is significant existing industrial activity, market interest and future industrial land identified. These are: West Industrial Node Airport Industrial Node North Industrial Node South Industrial Node Melton Industrial Node Pakenham Industrial Node

  • This dataset is derived from the Melway directory and contains the map indices for the 1:15 000 Queenscliffe maps.

  • This data is now obsolete, current UDP data is available. Identifies all industrial land across the Melbourne and Geelong and the development status and size of each land parcel in hectares. This information maps all industrial zoned land and land of industrial nature, ie. includes land within Special use zones, Airport Business Park, Business 3 Zones and Comprehensive Development Zone in Whittlesea. Each land parcel is assessed as being either Unavaillable or Supply industrial land and colour coded by as a combination of this and the zoning.

  • This layer contains the yearly Natural Resource Management standard outputs reported by CMAs. The raw submissions have gone through a statewide consolidation process which QAs selected common attributes.

  • VCMP Sites - Shorelines The Shorelines dataset features short-term and long-term shorelines across sites monitored by the Victorian Coastal Monitoring Program (VCMP) along Victoria's coastline, spatially represented as polyline data. The VCMP drone survey short-term outputs include shorelines for each survey, taking the ‘shoreline’ as the +1 m AHD contour for Open Coast sites, and +0.5 m AHD contour for large bay sites. Output products include 1m Digital Surface Models (DSM) and Orthophotos (vegetation is included in UAV data). - Vertical uncertainty for the output digital surface model (DSM) is estimated at 0.1 m. - The shoreline proxy is defined as the point at which each transect first intersect a given contour (m, AHD): 1.0 m AHD for open coasts and 0.5 m AHD for bay sites - Intersection points are joined alongshore to create a shoreline, noting the alongshore spacing (30-m) may be too low to define complex, small-scale features. - Assuming a beach face slope of 1-in-10, a 0.1 m vertical uncertainty in the survey DSM equates to cross-shore uncertainty of 1 m in shoreline position. Digital Earth Australia (DEA) coastlines A mean annual mid-tide shoreline is extracted from satellite imagery using sub-pixel identification methods, for the period 1988 to 2021, at 30-m alongshore spacing (Bishop-Taylor et al., 2021). - DEA shorelines have an estimated uncertainty of 1-3 m, with a precision limit on shoreline trends of 0.31 m/yr, i.e., trends below this threshold are insignificant. - DEA have known issues around cliffed areas, leading to higher (unconstrained) uncertainty in some cliffed areas. DEA outputs in such areas should be treated with caution. Aerial Imagery Shorelines Aerial images are hosted and geo-rectified by DEECA's Coordinated Imagery Program. Based on control point checks by VCMP, newer images (approx. post-2000) are estimated to have horizontal uncertainty of 3-m or less. Older images (pre-2000) can have greater uncertainty, estimated at up to 10-m. Older images (<1960) may have larger errors (unconstrained) and should be treated with caution. - Backshore line: Extracted for open coast and bay sites. Identified manually as the onshore extent of the active sandy beach. Depending on morphology, the backshore line may be defined vegetation, dune toe, cliff toe and / or a coastal protection structure (sea wall or revetment). - Shoreline proxy line: Extracted for bay sites only (with low wave energy). Identified manually as the instantaneous wet/dry line, with no tidal correction. - Sites with larger tidal ranges (e.g., Cowes) would be expected to have larger uncertainty in shoreline position and caution is advised. All shoreline data (short-term VCMP drone and long-term DEA satellite) are interpolated to the same set of 30-m spaced transects, based on the Digital Earth Australia 2019 product.
