The DSE Natural Resources Division seeks to establish an ongoing land cover mapping program to improve knowledge of land and biodiversity assets across the state. This program will contribute directly towards monitoring and reporting on progress towards State Wide Natural Resource Management outcomes and will improve the States ability to demonstrate the impact of policy, strategy and investment. The imagery will be manually interpreted and mapped for land cover types and stratified in a manner to facilitate targeted analysis of land cover. The 2009-10 CIP Vic Land Cover Photo Project will capture and provide photography for areas not covered by the 2008-9 CIP photography projects.

The Strzelecki Ranges area was captured by Photomapping Services using a Optech Gemini LiDAR system (Airborne Laser Scanning) between the 11th and 23rd of October 2009. The data was captured in order to provide bare earth DTM and contours.

This layer represents the spatial extent, species distrubtion and density of seagrass meadows within the Gippsland Lakes. This layer is a result of a baseline survey of seagrass within the Gippsland Lakes. Ecological research into the health of seagrass meadows requires the type of detailed information collected in this baseline survey. This information will be used to establish future monitoring programs and it is envisaged that these areas will be re-surveyed every 5 years to detect macro changes.

The photography is captured for Local and State Governments for use as a general GIS backdrop and to support topographic features maintenance.

Captured as part of the 2009-10 CIP, this 35cm orthorectified imagery will be used for a variety of applications where medium resolution imagery is required.

The proposed layer for East Gippsland's modelled old-growth forest derived from both vector and grid based analysis using disturbance data that post dates the source old-growth analyses. Areas delineated as old growth forest are identified to meet the Victorian definition of old-growth forest based on a set of modelling criteria, rules and input datasets. The data is not reliable at scales less than 1:100,000 (ie 1:25,000), not all old-growth polygons have been confirmed by field checking and the reliability of the modelled linework has not been verified.

The 2007-8 Southern Water Rural Water LiDAR project collected high accuracy LiDAR data covering parts of the Macalister Irrigation District, Latrobe Valley, Victoria & Latrobe River Flood Plain. From the raw LiDAR data, a suite of elevation products was generated including 1m DEM and 0.5m Contours. 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. Project Products: DEM, Contours, raw LiDAR
