摘要

1998年春天，大火摧毁了印度尼西亚婆罗洲岛加里曼丹帖木儿的大片热带雨林。作者报告了协同使用NOAA-AVHRR和多时相ERS-2 SAR数据分析该灾害的结果。利用1998年1月至4月期间获得的150多个NOAA-AVHRR热点数据集的时间序列和6个ERS-2场景的多时间序列，他们能够绘制出燃烧区域并追踪到一些火灾的起源。通过建立热点密度分布与多时相ERS图像中检测到的烧伤疤痕之间的关系，可以大致估算出全省的烧伤面积。根据这一基于NOAA-AVHRR的预测，仅在加里曼丹铁木尔地区，受火灾严重影响的总面积约为400万公顷。

Evaluation of the 1998 forest fires in East-Kalimantan (Indonesia) using NOAA-AVHRR hotspot data and multitemporal ERS-2 SAR images

In spring 1998 fires have devastated large areas of tropical rainforests in Kalimantan Timur on the island of Borneo in Indonesia. The authors report on results of the synergistic use of NOAA-AVHRR and multitemporal ERS-2 SAR data to analyze this disaster. Using a temporal sequence of more than 150 NOAA-AVHRR hotspot data sets acquired from January to April 1998 and a multitemporal series of 6 ERS-2 scenes they were able to map the burned area and trace the origins of some fires. By establishing a relation between hotspot density distribution and burned scars detected in multitemporal ERS images they were able to roughly estimate the burned area for the whole province. According to this NOAA-AVHRR based projection the total area severely affected by fire in Kalimantan Timur alone is approximately 4 mil. Ha.
