Based On The Web GIS Forest Fire Protection System Design And Implementation

Forest fires, sudden strong destructive, affecting a wide range of features such as forestfires is not only a serious threat to the safety of the forest resources, but also underminesthe human ecological environment and human lives and property of causing serious harm.Therefore, in order to avoid and reduce the damage caused by forest fires, an accurateunderstanding of fire took place and the fire spread of the scientific analysis of forest fireconditions and laws, in a timely manner to predict the extent of forest fires before they caneffectively reduce the forest fire prevention and fire-fighting operations, blindness,effectively improved the purpose of forest fire prevention and planning.With the continuous development of network technology, network geographicinformation system (WebGIS) has become a geographic information system (GIS) researchfocus, it is released and the use of GIS spatial data provides a convenient way.The WebGIS application in the forest fire prevention system, Web GIS advantage was given fullplay.This paper mainly discusses the basic principle of Web GIS, forest fire preventionrequirement analysis and system design, database design, system of forest fire preventionforest fire system etc..Analysis of the forest fire prevention system and WebGIS thedevelopment situation at home and abroad, the basic principles of WebGIS in WebGISknowledge, characteristics, functions, main technical methods and construction mode, WebServices architecture and the related techniques are described, according to the B/S(Browser/server) structure and its advantages, design WebGIS forest fire preventionsystem of various types of database.Combined with the requirements and practice of forestfire prevention, forest fire prevention system of WebGIS overall function, structure,processes and WebGIS forest fire prevention system system design, the system through theInternet/Intranet published on Web forestry geographic information spatial data, for the user to provide geographic information browsing, editing, space position and shortest pathanalysis function, meet the needs of different users of forestry geographic informationspatial data needs, provide support for forest fire prevention.
