Building The System About Information Storaging Andvisualization In Vineyard Based On Open Source WebGIS

In recent years,grape planting area and yield are gradually increased in China,and the industry of grape is becoming the important form in the Chinese agricultural industry.But there is a large number work about the information monitoring and management in the actual production.Therefore,it's seriously necessary to establish the vineyard management system.WebGIS makes full use of the characteristics of Internet real-time interactivity and low cost.It can improve and expand the traditional stand-alone GIS system and provide fast.Based on the WebGIS can obtain the actual situation and dynamic changes of vineyard information in time,so as to achieve the visualization of vineyard's management.According to the actual application requirements of the information storaging and visualization in the vineyard,this paper based on the vineyard data of Yongning in Ningxia Province establishes the vineyard system about the information storing and visualization under B/S module.The main contents and conclusions of this paper are as follows:(1)The systems analysis of the information storaging and visualization in the vineyard.Making a grape-growing region in the Yongning in Ningxia Province as an example,this paper completes the demand analysis about function,data and performance of the information storaging and visualization in the vineyard based on the vineyard managers' requirement.At the same time,the paper completes the feasibility analysis about technology,economy and operation for the process of system development and realization.The general design of system.The system overall architecture uses three layers structure about “data-service-presentation”.(2)Storaging the data.IIn data storage aspect.The system database chooses open source database PostgreSQL as a relational database.It mainly used to store the data such as the user's information,the data of farming activities and the basic information of field.Its plug-in PostGIS used to store spatial data including the vector map about division of the field.It can make the vineyard spatial data and non spatial data to unified management based on the design of database.(3)The implementation of system function.Through the realization of all layers about the system,this paper should integrate all technology and services,in order to satisfy the customers' requirements.Finally,this paper establishes the vineyard system about the information storing and visualization based on open source WebGIS.The system can realize five fuctions: the user information management function mainly used to implement the registration and login of the manager;the weather forecast function,whitch can call the public meteorological service,used to realize the weather forecast for the next period of time;the basic function of the map achieved the user for the basic operation of the map by loading the public and vector map;farming progress fuction,can let the manager understand the horzontal comparison of different field;field information visualization,used to query,add,delete the information,and compare the historical data.(4)System test.In the paper finished a lot of tests through the black box testing to test the system,including the fuction tests and compatibility test with different browsers,which can validate the system and the requirements are the same.
