This geotiff image is derived from MODIS and MSI satellite imagery by the North Australia and Rangelands Fire Information service. It is provided in the projection GCS_GDA_1994.

This image includes all firescars identified in 2025 across the Australian rangelands within the geographic limts described in the attached metadata txt file. 

The image is provided with a world file (tfw) for georeferencing.

Each pixel is tagged with a "Color Index" value (January = 1, February= 2 etc.) indicating the month in which the fire scar was detected as being burnt. The accuracy of the dating is limited by the mapping period - the time difference between the two satellite images that are compared to identify a burn event.

The image comes with the following colour map for each representing the pixel colours used on the NAFI website

	 R	 G	 B
Jan	130	100	130
Feb	110	130	165
Mar	55	75	55
Apr	70	175	145
May	51	255	153
Jun	51	255	51
Jul	51	132	51
Aug	255	255	0
Sep	255	150	75
Oct	255	128	255
Nov	160	60	160
Dec	50	0	50

Each pixel also has an "A" transparency value. All pixels in this downloaded dataset have no transparency (A=255). The fire scars displayed on the NAFI site have a 50% transparency to allow map features to be visible underneath them.

The data is also available as a download in shapefile format.

Details of the process for mapping fire scars is available on the NAFI website. More information on the mapping process and data reliability can be obtained from the North Australia and Rangelands Fire Information service (see email contact below).
