Abstract

Despite the fact that wildland fires have always been an integral part of many ecosystems, their increased frequency and intensity have reinforced the need of fire managers for updated and highly accurate information associated with the spatial distribution of forest fuels. In 2015, a fuel type mapping method was developed in the framework of the “National Observatory of Forest Fires (NOFFi)” project resulting in the generation of a national fuel type map. In this study, we aimed at examining the potential of the newly available Sentinel-2 satellite images for the improvement of the NOFFi’s mapping method in terms of accuracy and update effectiveness of the national fuel type map. Results demonstrate Sentinel-2 data will likely improve the resolution and reliability of national fuel type maps, increasing mapping efficiency for operational purposes.

摘要

尽管野火一直是许多生态系统不可分割的一部分，但其频率和强度的增加加强了火灾管理者对与森林燃料空间分布相关的更新和高度准确信息的需求。2015 年，在“国家森林火灾观测站 (NOFFi)”项目的框架内开发了燃料类型映射方法，从而生成了国家燃料类型图。在这项研究中，我们旨在检查新可用的 Sentinel-2 卫星图像在改进 NOFFi 制图方法在国家燃料类型图的准确性和更新有效性方面的潜力。结果表明，Sentinel-2 数据可能会提高国家燃料类型地图的分辨率和可靠性，从而提高用于运营目的的地图绘制效率。
