Three Parks Savanna Fire-effects Plot Network: Fire Scar Mapping, Northern Territory, Australia, 1989-2017

Abstract: This package contains Geotiff images of fire affected areas in Kakadu and Nitmiluk National Park for the years 1989 onwards, and Litchfield National Park for the years 1990 onwards. Pre-2000 images are based on Landsat imagery and attribution of each burnt pixel is either early or late. Images from 2000 onwards is based on NASA Moderate Resolution Imaging Spectroradiometer (MODIS) and each burnt pixel is tagged with the month that covers the largest part of the date interval in which the burnt pixel was detected; these Images are clipped from geotiff images of fire affected areas in far northern Australia available from North Australian Fire Information (NAFI) website. The images have a resolution of 250 m (pixel size). These data cover Kakadu, Litchfield and Nitmiluk National Parks, but are part of a larger data set that extends across far northern WA down to 21 degrees S, across the entire NT (down to 26 degrees S) and all of Qld (down to 29 degrees S). The NAFI mapping covers the years 2000 to present and since 2012, the mapping also includes northern SA down to 29 degrees S. Mapping landscapes north of 20 degrees S in WA, NT and Qld has been validated by aerial and on-ground transects across northern Australia.

Project funding: These data is collected as part of an ongoing program to map fire scars across northern Australian savannas and all of the NT. All fire scar mapping is available on the NAFI website and funded directly by the Federal Government and through Territory NRM.

The site is hosted at Charles Darwin University. Hotspot data from Landgate W.A. and Geoscience Australia is used to present hotspots and to highlight fires in the process of mapping fire scars.

Between 2012 and 2018 this project was part of, and funded through the Long Term Ecological Research Network (LTERN) a facility within the Terrestrial Ecosystem Research Network (TERN) and supported by the Australian Government through the National Collaborative Research Infrastructure Strategy.

摘要：本数据包包含1989年起卡卡杜（Kakadu）和尼特米卢克（Nitmiluk）国家公园，以及1990年起利奇菲尔德（Litchfield）国家公园的火灾影响区域Geotiff影像。2000年前的影像基于Landsat卫星数据，每个燃烧像素的属性标注为早季或晚季；2000年及以后的影像基于NASA中分辨率成像光谱仪（MODIS）数据，每个燃烧像素标记有其检测日期区间中占比最大的月份。这些影像从澳大利亚远北地区火灾影响区域的Geotiff影像中裁剪而来，可通过北澳大利亚火灾信息（NAFI）网站获取。影像分辨率为250米（像素大小）。

本数据覆盖卡卡杜、利奇菲尔德和尼特米卢克国家公园，但属于更大数据集的一部分——该数据集范围包括西澳大利亚州（WA）远北部（南至南纬21度）、整个北领地（NT，南至南纬26度）及昆士兰州（Qld，南至南纬29度）。NAFI的制图覆盖2000年至今，2012年起进一步扩展至南澳大利亚州（SA）北部（南至南纬29度）；西澳大利亚州、北领地和昆士兰州南纬20度以北区域的景观制图已通过澳大利亚北部的航空与地面样带调查验证。

项目资金：本数据是澳大利亚北部稀树草原及整个北领地火灾疤痕制图持续项目的一部分。所有火灾疤痕制图可在NAFI网站获取，资金由联邦政府直接资助及领地自然资源管理局（Territory NRM）提供。

该网站由查尔斯·达尔文大学托管。西澳大利亚州Landgate与澳大利亚地球科学局的热点数据用于展示热点，并在火灾疤痕制图过程中突出火灾区域。

2012-2018年，本项目是长期生态研究网络（LTERN）的一部分并获其资助；LTERN是陆地生态系统研究网络（TERN）旗下设施，由澳大利亚政府通过国家协作研究基础设施战略支持。
