Developing state of the art approaches to detect and characterize fire events using high spatial and temporal remote sensing imagery

需要有有效的测量和监测工具，以便在精细的空间尺度上和接近真实的时间内探测、量化和确定火灾的原因。在全球范围内，在接近真实的时间内检测火灾是公司的一项运营要求，特别是在热带地区，负责确保森林资源的可持续利用。卫星遥感是探测和监测火灾以及评估森林覆盖率随时间变化的重要工具。目前，我们依赖于光学传感器，如大地卫星和中分辨率成像光谱仪，然而，这些数据存在挑战，特别是在高云层覆盖，雾霾地区，以及近实时检测小火灾事件。Tanka是一家总部位于温哥华的高科技公司，它利用小卫星星座获得的遥感图像，开发了一种商业解决方案。这些小型卫星重量轻、体积小、成本低，因此可以随时发射许多卫星，从而可以在地球仪的任何地方快速获取图像。该项目旨在审查、测试和演示利用Tanka提供的高时空遥感图像探测火灾事件并确定其特征的新技术，并在加拿大和全球进行测试。

Effective measurement and monitoring tools for detecting, quantifying and attributing fires are required at finespatial scales and in close to real time. Globally, detection of fires in near real time is an operational imperativefor companies especially in the tropics charged with ensuring sustainable use of forest resources. Satelliteremote sensing is a critical tool for detecting and monitoring fires as well as assessing changes in forest coverover time. Currently we rely on optical sensors, such as Landsat and MODIS however, there are challengeswith these data especially in regions of high cloud cover, haze, as well as for detecting small fire events in nearreal time. Tanka, a Vancouver-based, high tech company has developed a commercial solution to this needglobally, by utilizing remote sensing imagery acquired by the Planet constellation of small-sats. The lightweight, small size and low cost nature of these small satellites allow many to be launched consecutivelyresulting in rapid image acquisition anywhere on the globe. This project is designed to review, test anddemonstrate new techniques to detect and characterize fire events on high spatial and temporal remote sensingimagery provided by Tanka over test cases in Canada and globally.
