Forest fires are one of the most common disasters and seriously endanger human life. Timely and accurate monitoring of forest fires is essential for fighting fires and reducing losses. At present, active forest fires monitoring with satellite is mainly based on low spatial resolution polar or geostationary orbit satellites. The spatial resolution is too low, which makes it impossible to detect small-scale fires and master detailed fire situation. In response to this problem, we prospect a near-real-time medium and high spatial resolution forest fire monitoring system, based on the rapid development of medium and high spatial resolution satellite sensors, data sharing policy and data processing capabilities in recent years. This paper summarizes the research status and related shortages in 4 aspects, including basic principles of forest fire monitoring, currently available medium and high spatial resolution satellite data and its characteristics, active forest fire monitoring algorithms and data sharing and cloud storage and computation, and propose a framework of a near-real-time global medium and high spatial resolution forest fire monitoring system. The construction of this system can form an important supplement to the existing coarse resolution forest fire monitoring system, and its combination with the drone and ground monitoring system will also significantly improve the large-scale forest fire monitoring capability.
