Abstract

Video monitoring plays a crucial role in forest fire monitoring system,and placing video monitoring points can effectively enhance the level of forest fire detection.This study focuses on Yuhexian County,Lishui City,Zhejiang Province.Using digital elevation models(DEM),visual field analysis and reverse visual field analysis techniques were employed to assess the effectiveness of placing video monitoring probes within different visibility ranges.The study identifies a need for 86 additional video monitoring points,comprising 29 dual-spectrum probes and 57 spherical probes.Following optimization,the coverage area of monitored forest land increased from 11.67% to 85.12% of the county's vegetated forest.This optimization plan offers a scientific foundation for enhancing the layout of the forest fire video monitoring system in Yuhexian County,and serves as a technical reference for other regions to improve forest monitoring coverage using geographic information technology.

Key words： forest fire; Yunhe County; visibility analysis; video monitoring
