This photography was captured to assess flood damage along Selected Rivers within Goulburn Broken CMA. The Georeferenced (reduced accuracy) image includes 3 visible bands and tiled into 1km tiles. It is available in both TIFF and ECW compress format.

Projection data is described in the gridcode column of the attribute table. This number is 1000 times the actual value (retained in this form to capture significant figures through map processing). For example, "Gridcode -23599" equates to -24% (rainfall) and "Gridcode 1986" equates to 2.0 degrees Celsius (temperature). The results are from 23 climate models that were available for the IPCC Fourth Assessment Report (2007). It is assumed that that the model results give a representation of the real world response to a specific emissions scenario. The IPCC (2007) estimates of global warming are relative to the period 1980-1999. For convenience, the baseline is often called 1990. Projections are given for 2030 and 2070 but, of course, individual years can vary markedly within any climate period, so the values can be taken as representative of the decade around the single year stated, i.e. projections for 2030 are representative of 2026-2035. Natural variability (independent of greenhouse gas forcing) can cause decadal means to vary and estimates of this effect are included in the estimates of uncertainties. The projections comprise a central estimate and a range of uncertainty. The central estimate is the median or 50th percentile - of the model results, while the uncertainty range is based on two extreme values the 10th and 90th percentiles. 10% of values fall below the 10th percentile and 10% of values lie above the 90th percentile. Greater emphasis is given to projections from models that best simulate the present climate. The weightings are based on statistical measures of how well each model can simulate the 1975-2004 average patterns of rainfall, temperature, and sea level pressure over Australia. Subregions of Victoria are indicated. Victoria has an integrated catchment management system established under the Catchment and Land Protection Act 1994 (the CaLP Act). Under the CaLP Act, Victoria is divided into ten catchment regions, with a Catchment Management Authority (CMA) established for each region.

This is one of a series of restricted layers that identifies the nesting areas for threatened Egret species and records areas where breeding was confirmed and also identifies areas where breeding may have occurred in the past. Where breeding has occurred the year and month where available are listed. The site name is also given where known.

The Wombat State Forest represents a gap in MWs recent elevation data coverage (both LiDAR and Photogrammetric). In addition, DSE sees an opportunity to expand MW AOI to complete the entire western side of the Port Phillip and Western Port CMA with high accuracy LiDAR coverage. This would encompass the Wombat State Park area and supersede pre-existing, lower accuracy elevation data sets. This coverage would adjoin the western edge of the Melbourne LiDAR project and leave only the extreme South Eastern section of the PPWP CMA not covered by high accuracy LiDAR data. AAM was commissioned by the Department of Sustainability and Environment to conduct a LiDAR survey over the North West Melbourne Area. The project area, comprising a total area of approximatley 2600 square kilometres, has been divided into 3 sub areas.

River condition in Victoria is assessed every 5 years using the Index of Stream Condition (ISC). The Department of Environment and Primary Industries (DEPI) has developed a methodology to assess components of the ISC using remote sensing techniques, specifically LIDAR and aerial photography. As such, a State Wide mapping project was undertaken in 2009-12 to accurately map the riparian vegetation and physical form components (metrics) of the ISC using LiDAR and imagery data. Remote sensing data collected includes 15cm true colour infra-red aerial photography and four return multi-pulse LiDAR data. These were used to derive a range of standard and non-standard physical form and riparian vegetation raster datasets. The project was managed on a CMA by CMA basis with all source and derived datasets being organised this way. In addition to the remote sensing and derived raster products, a set of vector products and tabular data has also been generated. These further represent and define the physical form and riparian characteristics of the ISC rivers and contain the ISC scoring data.
