Research On Key Technologies And Appl Ication Of 3D GIS For Smart Forest Plat Form

Due to the increasingly prominent environmental problems caused by high levels of industrialization and urbanization,the requirements for landscaping and ecological construction have been continuously improved.The method of real-time monitoring of the forest environment has gradually shifted from manual monitoring to automated monitoring.Automatic continuous monitoring systems and computer technologies have been widely used in forest environmental monitoring.GIS technology plays a leading role in the field of forest environmental monitoring and application.With the continuous enrichment and innovation of three-dimensional GIS technology,the application of three-dimensional GIS technology in smart forest monitoring systems has become the main development trend of forest management information.Based on the wireless sensor network data acquisition system can quickly capture the environmental data transmitted to the base station through wireless communication,and three-dimensional GIS as a spatial data processing and analysis technology tools,has developed into a powerful data processing system.For the current three-dimensional forest monitoring system,there are many problems,such as the low degree of three-dimensional model simulation,lack of real-time monitoring of environmental data.This paper clarifies an emerging model of the application of 3D GIS in intelligent forest information management.It combines the wireless sensor network with 3D GIS technology to realize the real-time monitoring and visual space-time expression of the forest environment.First,the forest-related data were obtained through actual surveys,field measurements,and the use of existing data to construct three-dimensional forest models.Then,according to the needs of forest environmental monitoring,a forest environment wireless sensor network is established,and data fusion algorithms are used in the network to improve data quality.Secondly,according to the needs analysis of the three-dimensional forest monitoring platform,the main functions of the system are determined and developed,and on the basis of three-dimensional landscape visualization and data analysis,the forest real-time monitoring function is added.Send the data obtained from the wireless sensor network monitoring to the 3D GIS system to process the data and display the data on the 3D model in real time to collect data in real time,process information,update data,analyze data,and determine the health status of the forest environment.the goal of.It made up for the deficiencies in the traditional forest information monitoring model and made the forest management decision more scientific and reasonable.In addition,through the design of multiple experiments,the feasibility of the three-dimensional forest monitoring platform was verified.Finally,the problems and challenges that still exist in the three-dimensional forest monitoring system are summarized,and it is verified that the forest environment status can be judged through the three-dimensional forest monitoring platform in the future.
