Abstract Geotiff image of the time
in years since areas were last burnt in northern Australia for the period 2000
- 2024 based on MODIS and MSI satellite sensors. The image has a resolution of
250m per pixel and each burnt pixel is tagged with an attribute (Band 1) that
corresponds to the number of years since that pixel has been detected as being
burnt in the 25 year period 2000 to 2024 with no data indicating it has not
been burnt in that period. The data is based on monthly fire scar mapping and
extends across the WA rangelands, across the entire NT (down to 26 degrees S)
and across northern Qld down to aprox. 20 degrees S.
The monthly fire scar mapping of landscapes north of 20 degrees S has been
validated by aerial transects and checked using high resolution imagery across
northern Australia.

Lineage Statement The time since last burnt mapping is based
on GIS analysis of monthly burnt area mapping from each of the years 2000 to
2024. This data was produced through analysing the individual burnt area raster
grids (in Arc-GIS) from 2000-2024 where grid cells were attributed with the
values equal to the number of years since it had been last burnt up to a value
of 25 - with a value of 26 if it had not been burnt at all in the period.The burnt area mapping was based on analysis of
imagery from the Moderate Resolution Imaging Spectroradiometer on NASA’s Terra
and Aqua satellites and the Multispectral instrument on ESA's Sentinel-2
satellite. At least two images of different dates were compared to detect fire
affected areas. Image analysing software, manual inspection of the image and
other datasets such as hotspot data were used to produce the final burnt area
product that the fire frequencies are based on.
