Research And Development Of Forest Resource Data Visualization Prototype System Based On WebGIS

Forestry informatization is an important part of modern forestry construction,which plays an important role in promoting the development of forestry science.The useful data in forestry,after combing,in the form of people willing to accept,show to the majority of forestry science and technology workers and the public has become an urgent need.However,the traditional statistical data of forestry resources are expressed by means of text description and form,which is simple in form and low in visualization.It is difficult to reflect the spatial distribution of forest resource statistics.At present,there are few researches on the visualization of forest resource statistics in the aspects of visualization of forest resources,visualization of forest stand and visualization of growth model.With the rapid development of WebGIS and network front-end technology,it provides a new platform for the display of forestry resource statistics.The use of WebGIS platform can be a comprehensive display of forest resource statistics,and a wealth of visual effects to meet the growing needs of users of information needs.This paper constructs a visualization prototype system of forest resource statistics based on WebGIS,introduces the key technology,design method and operation effect of the system,and puts forward the future development and research prospect of the system.The system uses the three-tier architecture in B / S mode: the data layer stores four world forest resource statistics,China's eight forest resource inventory data and the 2015 international important wetland data,using spatial data and attribute data to separate the storage model;The background service layer uses ArcGIS Server and Web Service to provide data interface services for the front end;the front page layer uses ArcGIS API for JavaScript to implement the specific module.To improve the visualization,the Highcharts framework is used to graphically display the data.The system uses WebGIS technology to realize the visualization system of forestry resource visualization.The system is divided into map basic operation module,query module,thematic map display module and spatial analysis module.And the use of HighCharts chart framework to achieve a dynamic display of front-end data,enriched the form of forest resource statistics,and enhance the front page of the dynamic interactive and 3D display effect.The research of this paper enriches the expression of forest resource statistics data,improves the visualization level of forestry resources statistics,and provides some reference value for the visualization of forestry resource statistics in the future.
