Design And Implementation Of Land-based Map Visual Website Based On PHP

With the continuous development of computer technology,the world has entered the information society.The acquisition of information becomes more and more important.Now many enterprises and institutions are actively building their own websites and using the industry's characteristics to develop special service modules within the website to promote data opening and information sharing,thereby enhancing their competitiveness.In recent years,PHP has set off an upsurge in Web development.Its language structure is simple and it has very powerful functions.It supports almost all popular databases and operating systems.Using PHP technology,it is efficient and convenient when developing website modules,and later management and maintenance are relatively Simple,basically solved the previous dependence on developers.The internship organization builds a portal site according to its needs and compares it with the portal industry of the same industry,and further strengthens its service in the industry.Therefore,this paper takes the realization of the special land data service as an example to study the design and implementation of the thematic service system of the website.The main work done is:(1)Determine the storage directory and file naming rules for the original data and thematic map product data.The original land data is divided into five types:farmland data,woodland grassland data,water area data,urban and rural areas,industrial and mining resident land data,and unutilized land data.All types of data are sorted by district and county deposit and year,and the file name is classified by land data.,district and county codes,years,secondary classification codes,identification codes and extensions.Thematic map product data is stored by topic type.Each topic type file contains a number of thematic map data.The product file name includes the thematic map name,production date and extension.(2)Designed web site management content and services.The non-spatial data information used to store the site configuration and the spatial data used for the geographic information service are stored in the MySQL database and the SQL Server database,respectively,and two library data are integrated.Based on ArcGIS Server,it produces and publishes various thematic map data to provide users with thematic map services.Together with on-line map queries,address navigation and other functions,it constitutes the geographic information service model of the website and reflects the characteristics of the website and industry.(3)The information management module based on the PHP development language and MySQL database development website,including the function of adding,editing,and deleting posting information,realizing the real-time management of the content published on the website front-end;making and releasing thematic maps based on ArcGIS Server and SQL server database,through the information management module in the front of the site to achieve visualization.(4)Optimize the code from the three aspects of filtering user input,optimizing SQL query,and filtering output,strengthening the protection of security vulnerabilities in the process of web site front-end data interaction,and protecting the server-side user and resource data by optimizing the server configuration.Security.
