  • Geological Phase Areas - Polygons

  • Captured as part of the 2015-16 CIP this 17cm relaxed accuracy photography covers the Gellibrand River catchment area in the Otway Ranges

  • Relaxed accuracy 4 band (RGBi) photography over several reaches along the Murray River to capture the October 2016 floods

  • This layer features the area cells used to record Catch and Effort data for the Port Phillip Bay commercial fisheries since April 1998. This layer is used by the Port Phillip Bay, Port Phillip Bay (Mussel Bait) and Port Phillip Bay (Purse Seine) fisheries. It is based on divisions of 5 minutes latitude by 5 minutes longitude.

  • As part of the 2016-17 CIP, this project is for three Melbourne epochs (Spring 2016, Summer 2016-17, Spring 2017) and one Geelong epoch (Spring 2017)of relaxed accuracy 10cm photography for use in the areas of rail maintenance, local council planning and the monitoring of urban growth by a variety of Local Government and State Agencies covering Greater Melbourne and Greater Geelong areas.

  • The LiDAR project was conducted under the 2015-16 Coordinated Imagery Program (CIP). LiDAR derived ground DTM and Contours are the primary products for the project. The source LiDAR point clouds have also been delivered to ICSM Level 2 Classification standard. This standard means that the Ground point classification has been manually checked and edited, but above ground classes have only been classified by automatic processing and have not been manually edited. The above ground point classes have been inspected but not formerly assessed and should be used with caution. LiDAR was captured to acheive a vertical accuracy of +/- 10cm RMSE all sites. The classified unthinned ground points were used to derive a 1 metre gridded 2D digital elevation model and 0.5m interval Contours of a quality suitable for drainage asset management and hydrological design. The township of Heywood has been levelled and matched to existing +/-10cm RMSE vertical accuracy LiDAR data from the 2010-11 Floodplains LiDAR Stage 2 - Glenelg Hopkins CMA project. The sites of Plantation, Koroit and Portland have been levelled and matched to existing +/-10cm RMSE vertical accuracy LiDAR data from the 2012-13 Victorian Coastal LiDAR Level 3 Classification Project.

  • 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.

  • The section of Princes Highway from Lakes Entrance to the NSW border was captured using the Optech Gemini LiDAR system (Airborne Laser Scanning) from the 21st to 24th of October 2010. The data was captured in order to provide DEM information.

  • This layer shows the modelled Growth Stage Structure (GSS) status of vegetation on Victorian public land between years 2002 and 2015. Vegetation GSS relates to the stages of vegetation succession. The GSS status of vegetation depends on when it was last burnt. For a full understanding of the concepts on which this dataset is based, please see DSE Fire and adaptive management report no. 84, "Growth stages and tolerable fire intervals for Victoria's native vegetation data sets", David Cheal, 2010. The dataset categorises the landscape into six categories: Juvenile; Adolescent; Mature; Old; Public land with no recorded fire history; and Private land. The four growth stages are a simplification from those provided in Cheal (2010) and encompass these groupings: (1) Juvenile (Renewal, Juvenility, Founding) - from immediate post-fire renewal to establishment, including the period before which the full floristic complement of species is reproductive (1) Adolescent (Adolescence) - the vegetation is relatively young, and the full complement of species is reproductive, but not at the rate characterising mature vegetation (3) Mature (Early Maturity, Maturity, Vigorous Maturity, Stasis, Established) - including when dominant species are fully reproductive through to stasis, when vegetation structure and reproductive capacity stabilise (4) Old (Waning, Senescence) - characterised by declining reproduction of the dominant species and decreasing propagule banks; if left undisturbed, vegetation may become senescent and is then unlikely to be reconstituted following fire. The layer was created by the Fire and Emergency Management Division in the Department of Environment, Land, Water and Planning, and completed September 30th 2015.

  • As part of the 2015-16 CIP, this project contains true colour orthorectified 10cm aerial photography Covering Bass Coast LGA and Phillip Island for use by a variety of Local Government, Water Authority and Nature Conservation agencies.
