October 2017:Fire histories extended in WA
The long term 250m fire histories from the year 2000 have been extended in WA so they now extend south of the Kimberley region to cover the WA rangelands. These fire histories can be viewed on NAFI under the "View Fire History" tab or they can be downloaded as a geotif , shapefile or kml from the "Download Data" tab (then use the data as image or shapefile > Fire history menu or the Data as kml file > Fire history patterns menu).

September 2017:New source of satellite image
The satellite image used by NAFI that appears on the home page and is used in the Check smoke & cloud conditions tool in the Track Fires > Check conditions menu has been changed. This image is provided by Geoscience Australia and they have recently changed the source from MODIS polar-orbiting satellites to the Himawari 8 Geostationary satellite.

The new image is updated more frequently. Whereas the old satellite images were updated a couple of times during daylight hours, the new geostationary satellite provides images every hour around the clock. So you will see dark images overnight. The images show conditions usually around 2-3 hours before they are displayed, so opening the site first thing in the morning you will see a dark night image from a few hours earlier. However, the images may sometimes be delayed by 6 hours or more.

The new image is also coarser than the old image, so you will not be able to zoom in as much to get images of smoke from smaller fires.

June 2017:Automated fire scar mapping now available
Daily updated automated 250m fire scar mapping is now available on NAFI. Go to More Tools > Firescars 250m > Auto Scars (last 60 days) - at the bottom of the menu. The auto fire scars are colour coded by accuracy confidence levels with redder colours more confident and bluer colours less confident. The most recently updated auto-scars tend to be less confident as the algorithm builds accuracy over time.

These fire scars can be useful for tracking recent fires before the regular mapping updates. Note that the auto scars may not work as well in wetter landscapes in Qld.

This is a test product provided for the 2017 fire season by Maitec. For more information contact stefan.maier@maitec.com.au.

June 2017:High Resolution Landsat fire scar imagery available for CYP
Regularly updated high resolution (30m) Landsat fire scar images for areas in Cape York Peninsula are now available from NAFI. Follow the link to "Landsat Fire Scar Images" on the NAFI front page. You may need to refresh the NAFI site in your browser. Available formats include kmz (for use in Google Earth) and geo-tiff (for use in mapping programs).

This imagery will be available for the 2017 northern fire season as part of a feasibility project supported by the Indigenous Land Corporation and CYP fire management groups.

March 2017:Rangelands 10 year Fire Histories updated
The recent fire histories covering most of the rangelands have been updated to 2007-2016 (i.e. covering the WA rangelands, the NT and QLD). These histories are now displayed on NAFI and are available for download as images and shapefiles from the "Download Data" tab under "Data as image or shapefile" > "Fire History".

The full rangelands fire history dating back to 2000 should be available later this year.

February 2017:Format of downloadable fire scars revised
The downloadable images of fire scars for the years 2013-2016 now have the pixels tagged with the month burnt - a change from the previous versions where pixels were tagged with a "Fire Scar Identifer" or FSID value that could be used to work out the mapping interval from an attached csv file. Feedback indicated this was a hard system to use. If you want to determine the mapping of the fire scars interval you can download the shapefile.

The image and shapefiles of annual fire scars are available from the "Download Data" tab.

July 2016: New tool to track spread of older fires
A new hotspot animation tool is available that can animate the spread of all fires back to 2000. This tool is useful for seeing how fires are pulled up by breaks, how they are affected by wind conditions and roughly where they started. Go to the "Track Fires" menu then choose "Check Fire Spread" and "Animate hotpots (older)".
