Project layer depicting housing activity over the years from 2005 and 2016

This layer provides an annual view of changes in lots and residential dwellings associated with housing development projects over each year for Metropolitan Melbourne defined by the 32 local government authorities. Project lot and dwelling information is assigned to polygons representing housing development projects that comprise one or more land parcels for the particular year. Projects are only identified where there is development activity or change such as 
demolition or construction.
Key fields include: Number of lots pre and post development; residential dwellings pre and post development; vacant lots pre and post development; total demolitions and constructed dwellings; and total construction projects. Polygon linework is consistent with the corresponding Parcel View - Vicmap Property dataset (VMPROP_PARCEL_VIEW) for when a project was first defined.

Port Fairy Seawall Failure Hazard Lines

The Port Fairy Local Coastal Hazard Assessment (LCHA) provides information on the extent of coastal hazards and their physical impacts for the Port Fairy coastal environment.

This data considers setback of the present day shoreline due to coastal erosion if existing seawall (where present) was to fail. The four key components of coastal setback that are incorporated into this hazard line are:
- S1, allowance for short term storm erosion (storm demand 100 year ARI);
- S2, allowance for dune stability (zone of reduced foundation capacity);
- S3, allowance for ongoing underlying recession; and,
- S4, allowance for recession due to future sea level rise.

The total design setback (S) for three planning horizons comprises:
- Present day: S = S1 + S2;
- 2050: S = S1 + S2 + S3(2050) + S4(2050);
- 2080: S = S1 + S2 + S3(2080) + S4(2080); and
- 2100: S = S1 + S2 + S3(2100) + S4(2100).

Sea level rise projections utilised for the planning horizons were 0.4 m for 2050, 0.8 m for 2080 and 1.2 m for 2100 respectively. Where appropriate, the +6 m AHD contour was used as a reference as it was considered to represent the coastal alignment reasonably. The crest of the rock revetment was used as the reference contour on the southern half of East Beach. For low-lying dune systems the +2 m AHD contour was used.

Details of the assumptions made in the derivation of this information can be found in project reports on the Our Coast website: http://www.ourcoast.org.au/cb_pages/resources.php.

2010 Index of Stream Condition - Toe of Bank line features

The ISC2010_TOE_OF_BANK line features represent the left and right stream bed lines of the river channel for each River Reach.

River condition in Victoria is assessed every 5 years using the Index of Stream Condition (ISC). The Department of Environment and Primary Industries (DEPI) developed a methodology to assess the Physical Form and Riparian Vegetation components of the ISC using remote sensing data, specifically LIDAR and aerial photography. 

A State Wide mapping project was undertaken in 2010-13 to accurately map the Physical Form and Riparian Vegetation metrics of the ISC . Other ISC metrics were not assessed in the project and were derived from other sources.

The Physical Form and Riparian Vegetation Metric products are a combination of mapped Vector and Raster data as well as Tabular Summary Statistics about the mapped features. In the context of the project, the term Metrics is used to refer to both the mapped features and the summary statistics. 

Remote sensing data used includes 15cm true colour and infra-red aerial photography and four return multi-pulse LiDAR data. This source data was used to derive a variety of Raster data sets including Digital Terrain Models, Slope, Vegetation Height and Vegetation Cover. The Digital Terrain and Slope rasters were used to map Physical Form metrics including Stream Bed, Top of Bank and River Centre Lines while the Vegetation Height and Cover rasters were used to map the Riparian Vegetation metrics.
The Project Report "Aerial Remote Sensing for Physical Channel Form and Riparian Vegetation Mapping" describes the remote sensing and mapping approach used to create this data set.

VCMP Sites - Shoreline Trends

VCMP Sites - Shoreline Trends

The Shoreline Trends dataset features short-term and long-term shoreline trends across sites monitored by the Victorian Coastal Monitoring Program (VCMP) along Victoria's coastline, spatially represented as point 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.

Drone survey data collection is performed as described in Pucino et al., 2021 and Ierodiaconou et al., 2022, and outlined as:
- Data processing and quality control conducted within the Propeller platform (https://vcmp.prpellr.com), with additional manual quality control checks, to achieve a horizontal-vertical uncertainty of 0.1 m or better (Pucino et al., 2021), with output products of Digital Surface Models (DSM) and ortho-mosaics.
- Analysis is conducted using a statewide framework of 30-m spaced transects

Shoreline change trends are determined for each transect, defining a ‘short-term trend’ as being based on the last 2-years of data.

Long-term shoreline trends are obtained for the period 1988 to 2021 (34 years) using the satellite extracted, annually averaged shorelines from Digital Earth Australia (DEA) coastlines (Bishop-Taylor et al., 2021).

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.

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 (&lt;1960) 
may have larger errors (unconstrained) and should be treated with caution. 

For all shoreline data sources (UAV, DEA, aerial), trends are calculated as a simple linear regression across 
the full dataset, at each transect, for each data source. Standard deviations and 95% confidence intervals 
are also included for each data point.

Vertical uncertainty for the output digital surface model (DSM) is estimated at 0.1 m

SubSurface Geophysics (1:250,000), Geological Interpretation of Subsurface Geophysical Features, at level 1

This dataset contains interpreted geological data, using combined interpretations of airborne magnetic, radiometric and gravity survey data, mapped at 1:250,000 of deeply buried geological units. In this layer units, along with their associated linework, have been classified as 'deep' since they reside beneath other geophysically interpreted units which are usually themselves below the mapped surface geology.

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, structural lines, miscellaneous lines and metamorphism.

Potential Groundwater Dependent Ecosystem (GDE) - Species Tolerance Grid

Potential Groundwater Dependent Ecosystems (GDE) are ecosystems identified within the landscape as likely to be at least partly dependent on groundwater. 

In 2011-2012 a species tolerance model was developed by Arthur Rylah Institute, collaborating with DPI, to provide a relative measure of sensitivity of those ecosystems to changes in groundwater availability and quality. The output was a species tolerance grid for Victoria.

Each GDE map unit has been assigned a species tolerance value based on the median of it's contributing grid cells.

2010 Index of Stream Condition Scores

The ISC2010_SCORES dataset represents the 2010 Index of Stream Condition (ISC) overall score and subindex scores for each ISC river reach in the state of Victoria. This was the third ISC assessment providing a snapshot of river health for major rivers and streams in Victoria, using data collected over a six-year period from 2004 to 2010. The methods used in 2010 differed to the 1999 and 2004 assessments. Method changes were undertaken to strike a balance between incorporating new scientific advances while maintaining compariability of results with the 1999 and 2004 benchmarks. The ISC 2010 provides scores for five components of stream condition: (i) hydrology (based on change in volume and seasonality of flow from natural conditions); (ii) physical form (based on bank stability, bed erosion or aggradation, influence of artificial barriers, and abundance and origin of coarse woody debris); (iii) streamside zone (based on types of plants; spatial extent, width, and intactness of riparian vegetation; regeneration of overstorey species, and condition of wetlands and billabongs); (iv) water quality (based on an assessment of phosphorus, turbidity, electrical conductivity and pH); and (v) aquatic life (based on number of families of macroinvertebrates). The Physical Form and Riparian Vegetation components of the ISC were mapped by the Department of Environment and Primary Industries (DEPI) in 2010-12 using LIDAR and aerial photography. Other ISC metrics were derived from other sources. Further information available at: https://www.water.vic.gov.au/waterways-and-catchments/rivers-estuaries-and-waterways/monitoring
