  • Fuel reduction burn aerial photography

  • This dataset consists of a series of approximate WSW to ENE oriented 'geological structures' interpreted from residual gravity bedrock depth in the Goulburn-Murray area of Victoria. These structures segment the Goulburn River Valley into an upper, middle and lower Goulburn bedrock valley system suggesting that it is a broadening out upland groundwater system for most of its length. The dataset was compiled by GHD to inform the report 'Potential Influences of Geological Structures on Groundwater Flow Systems' for DEPI's Secure Allocation Future Entitlements (SAFE) Project.

  • Land Status - Geothermal Energy Resources Act (GERA) - Other Parks (subset of PLM100_POLYGON)

  • This project consists of data that has been reprocessed by RPS and AAM for the purpose of creating an improved Victorian coastal DEM including contours based on the original data acquired in 2007. The purpose of this project is to reclassify the original level 2 classification LiDAR data into level 3 for input to a higher accuracy ICSM Level 3 classification (Level 3 DEM). LiDAR (Light Detection and Ranging) is an airborne remote sensing technique for rapid collection of terrain data. The sensor used for this LiDAR project collected XYZ and Intensity data for first and last return by bouncing a pulse from the aircraft to the surface that enables the height and intensity values to be calculated. Products derived from the following projects: 1. 2006-7 South West Elevation ¿ Coastal Elevation 2. 2007-8 Ninety Mile Beach LiDAR Project 3. West Gippsland LIDAR Project 4. 2007-8 South Gippsland and East Gippsland Coastal 9. 2009-10 Bunyip River Project Products: DEM, Contours, raw LiDAR

  • Modelled long term (1958-2005) average diffuse recharge (in mm) for April as calculated using the Ensym model. Includes rainfall recharge and irrigation recharge however excludes river / stream / channel / reservoir leakage. Ensym estimates daily spatial recharge by solving for physical processes using analytical solutions and empirical equations. Water entering the soil profile is initially determined by subtracting the calculated surface runoff from the total daily precipitation and irrigation. Once in the soil profile, water can be removed by evapotranspiration, lateral flow and downward movement if soil capacity is exceeded. Water fills up lower soil layers until it exits the soil profile and becomes drainage. Drainage is then partioned into sub surface lateral flow and recharge.

  • Geological structure measurements taken by Geological Survey of Victoria. Measurement methods - most of the structure measurements were collected in the field as part of the ongoing regional mapping program then entered into the corporate database. Measurements are taken using a geological compass. Surfaces are recorded as dip - dip direction. Lineations are recorded as plunge - azimuth. Declination measured to magnetic north then corrected to true north automatically within the database. A small amount of pre-1995 structural data has been digitised from previous maps. Field data is either recorded in a notebook in the field then typed into the database or recorded digitally in the field and automatically transferred into the database (this applies to the majority of data collected since 2002). Display - structural measurements have been divided into four categories to simplify display. Bedding contains measurements of sedimentary bedding where the bedding surface is upright, overturned or younging unknown. Foliation contains measurements of the commonly measured foliations seen in rocks such as cleavages etc. Folds contains measurements of structures directly associated with folds such as fold axis, axial surface etc. Other contains all other structural measurements including faults, joints, quartz vein orientations etc.

  • This dataset (and the derivative 95% confidence interval for upper and lower datasets) were created by CSIRO and provides a spatial coverage of estimates of the long term average annual recharge across Victoria. It is based upon regression equations between soil order, vegetation type and long term average annual rainfall. More details on the method used to estimate this dataset are provided in the report: Leaney et al (2011) Recharge and discharge estimation in data poor areas: Scientific reference guide. CSIRO: Water for a Healthy Country National Research Flagship.

  • This dataset is a raster layer of the Sherbrooke Group, Otway Basin in metres below sea level. Due to a number of deficiencies in mapping previously completed by 3D Geo for Southern Rural Water in 2011, a number of processes were applied to correct the Top and Base of the Sherbrooke Group. The dataset was compiled by GHD to inform the report 'Potential Influences of Geological Structures on Groundwater Flow Systems' for DEPI's Secure Allocation Future Entitlements (SAFE) Project.

  • Locations of Geologically Interesting Features within Victoria. The Geological Society of Australia (GSA) has assigned significance levels to each site - based on a set of criteria.
