Fire history overlay of most recent fires only showing scars
dataset:
FIRE_HISTORY_SCAR_LASTBURNT
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.

- Purpose
- This data is derived from the FIRE_HISTORY dataset. The layer stores details of the last time an area was known to be burnt by wildfire or prescribed burning. It is current to 2021/22 fire season and only shows fire scars not severity.

- Supplemental Information
- History: This data set has been derived from the Fire100_XY layer. Coverages based on year within the Fire100_XY layer have been overlayed with each other. This was performed in a cyclic manner based on one years data overlaying the preceding years. This allows for the most recent information to be the last information overlayed. As this dataset is wholly derived from Fire100_XY, attributes and lookup tables for Lastburnt100 have been mimicked. Layer design for Lastburnt100 has been maintained due to this dependency. Any changes identifiable in this layer design need to be addressed to the Fire100_XY dataset. Relationship to other Datasets: This dataset is wholly derived from Fire100_XY. Fire100_XY is updated annually and this layer will need to be re-derived to maintain its currency. This data is derived from FIRE_HISTORY_MASTER and FIRE_HISTORY_LASTBURNT Current Design Issues: The current layer design reflects the structure of DELWPs FIRES (FIREWEB) and FUEL MANAGEMENT (FMS) databases and emap spatial extents. The firekey attribute in the dataset provides the link to these two FFMVIC databases and CFAs IMS database. Other dataset attributes allow information annotated on source maps to be entered, especially in the case of historical fire information where no fire key is often provided to allow referencing to the relevent Fire database. The location attribute (that is replicated as part of the firekey attribute) can be either the former Forests Commission of Victoria (FCV) district, former Fire region, or current Fire District. It is currently proposed that only fire history information from the 1996/97 season inclusive will require the location and firekey fields to be completed. If historical fires are to have the firekey attribute recorded then this issue, particularly validation checks, will require further consideration. A flattened version of FIRE_SCAR Generated automatically from pythn ETL task, Future Design Issues: Future enhancements to this layer may include fire frequency information and possibly changing the layer into a raster format, ie. ArcInfo GRID. Related Documents: None

- Attribute Quality
- Based on attribute checking procedures, an error of 1 in 20 is reasonable for the fire year, ie. 95% attribute accuracy.

Lineage
- Description
- Dataset standardisation has occurred to bring all datasets into line with current structure. All tiles within the Fire100_XY have been processed using a standard aml tool to create Lastburnt100. Coverages based on year within the Fire100_XY layer have been overlayed with each other. This was performed in a cyclic manner based on one years data overlaying the preceding years, allowing for the most recent information to be the last information overlayed.
- Statement
- Dataset Source: Derived from Fire100_XY, which was constructed from regional fire records in the form of fire history maps. (Refer to Fire100_XY for further information) Dataset Originality: Derived
