November 2018: Shift to htpps address
To comply with new security standards, the NAFI site has shifted to an https web address. The regular address (www.firenorth.org.au) and older bookmarked addresses should be automatically re-directed to the new address. If you know someone is having problems reaching NAFI, they should use the www.firenorth.org.au address and bookmark that.

August 2018:Regularly updated curing maps for the NT now available
You can now view maps of curing (fuel dryness) for the NT that are updated every week. Under the "More Tools" tab in the left hand menu, go to Map Layers > Base where you will see three new layers: two "Current Curing" layers, one with 250m pixels and one with 5km pixels, plus a layer showing the BOM Fire Weather districts. The 5km curing layers is better suited for reporting against the fire weather districts. The curing layers will be updated at the start of each week. The curing data is sourced from Landgate WA. This feature comes from a collaboration between Bushfires NT, Landgate WA and Charles Darwin University.

May 2018:More archived fire histories available for download
You can now download fire histories for the 2000-16, 2000-15, 2000-14, 2000-13 and 2000-12 periods from NAFI: go to Download Data > Data as image or shapefile > Fire history archive. These older fire histories can be useful for gauging progress in fire management.

March 2018:NAFI Reports updated
The NAFI Reports (under the "Create Report" tab above the map) have now been updated with the latest fire histories for 2000-2017 and for 2008-2017.

March 2018:Fire histories updated
The Long term (2000-2017) and Last 10 years (2008-2017) fire histories are now viewable on NAFI (under the "View Fire History" tab) and available for download (go to "Download Data" tab > "Data as image or shapefile" > "Fire history" ). They are available as Fire Frequency, Late Fire Frequency (after July 31) and Time Since Last Burnt.

March 2018:2017 fire scar display no longer default
The previous year's fire scar display (which can be useful for managing fire that burn through into January) has now been removed as a default display when you enter the NAFI site. It can still be viewed by going to View Fire History > Past fire scars by month and ticking the box for 2017.

February 2018:
Google Earth links for past year's fire scars updated for the new year
The Google Earth kml links for past years' fire scars have been updated for 2018. You will need to download these new links to view previous years' fire scars by month and by year with the correct legends and updated menus on Google Earth. On NAFI, go to Download Data > Data as .kml file > Past years' fire scars.

February 2018:Fire scars updated for the new year
The 250m fire scar displays have been updated for 2018. The 2017 fire scars will continued to be displayed by default along with the 2018 scars for the next few weeks. The updated fire scars can also be used in the "Fire Scars By Year" reports on the reporting site.

A small area of the 2017 fire scar mapping remains to be finalised in the far south of the low rainfall methodology zone in Qld. SavBAT should be updated by mid February.

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 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.

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.

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)".
