  • This layer has been derived from FIRE_HISTORY data and represents the spatial extent of the last fires recorded, primarily on public land. The layer stores details of the last time an area was known to be burnt by wildfire or prescribed burning and represents a consecutive overlay of all FIRE_HISTORY layers, from older fire seasons to the most recent fire seasons. The data will show fire scars but not severity. This data set is current to 2021/22 fire season.

  • The fire severity classification is derived from a classification of a SPOT and Landsat TM woodlands fire severity index to map the fire severity of the February 2009 Victorian bush fires using ground control and air photograph analysis provided by DSE to Ecowise for validation. The classification is the final product derived using SPOT 4/5 satellite imagery with Landsat 5 imagery used on small areas where cloud or where SPOT imagery coverage was unavailable. Five of the eight classes have been labeled based on severity classes provided with the ground survey data. The remaining classes account for vegetation structures with no specific burn severity assigned. The area covered by the classification is approximately 460 by 300 km and is clipped to the extents of the fire effected lands (approximately 400 000 hectares).

  • Supporting mechanical works for the Fire Operations Program Indicates location of a combination of works being undertaken to support the Fire Operations Plan including fuelbreak improvement and roadside maintenance

  • This layer contains the line and polygon features depicting the Land Conservation Council Study Area boundaries according to the Statewide Assessment Report of 1989, with additional information showing historic studies. There are no boundaries for Special Investigations included in this dataset. An additional layer has been created showing later Environment Conservation Council Boundaries and the boundaries of some of the special investigations. Refer to ECC500

  • Polygon layer contains DELWP Land and Fire District Boundaries used for Forest and Fire Management operations.

  • This dataset is created by collating the current burnt area from field data and linescan data over the season. The final shapes are the final extent of both bushfires and planned burns. This data includes both FFMVIC and CFA fires and this data is QA by staff in both agencies. It is captured on emap and the final fire scar is downloaded to collated fire history. The final data is provided as a feed and is merged with the fireweb data to show fire cause.The data is limited to the last 10 years.

  • This layer has been derived from FIRE_HISTORY data and represents the spatial extent of the last fires recorded, primarily on public land. The layer stores details of the last time an area was known to be burnt by wildfire or prescribed burning and represents a consecutive overlay of all FIRE_HISTORY layers, from older fire seasons to the most recent fire seasons. This data set is current to 2021/22 fire season. There is no severity data for Gippsland in this version for season 18/19 and 19/20.

  • This dataset is created by sketching in the current burnt area from field data and linescan data. This data is updated every time the area of the fire is updated during an incident.The area is captured in the incident mapping system eMap.The final fire shape is then combined with the planned burn area data to create the FIRE_HISTORY dataset. This data includes both FFMVIC and CFA fires. . The layer will support fire prevention and suppression activities of DSE, and will be used to generate the FIRE100_{year} fire history datasets. This layer is the source of disturbance datasets used in the analysis of old-growth forest.

  • This layer represents the spatial extent of Strategic Permanent Fuel Breaks defined as a line.

  • A subset of the BURNPLAN15 data, which represents areas gazetted as Public Safety Zones. Data managed via DEPI Fire group. Data created by Anthony Cheesman (DEPI Hume Region). PSZ's for Fire Operations Plan are defined by being: 1/ in the approved FOP dataset; 2/ Not falling on freehold land; 3/ Not falling on parcel voids; 4/ Not falling on any public land tenure covered by Schedule 2 of the National Parks Act (nominally, any National Park). Areas meeting the above criteria but being less than 0.5ha are removed. Areas meeting the above criteria, not being in the DEPI F&L districts of East Metro, Midlands, Murray Goldfields or Otway, and being smaller than 10ha, are removed. Areas meeting the above criteria, but where the total area of eligible PSZ's for a given burn total less than 15% of the total burn area, are removed.
