基于服务的城乡建设用地增减挂钩项目可视化监管系统研究

Study on Visualization Supervision System of Decreasing Urban Construction Using Land and Increasing Rural Agricultural Land Based on Application Service

城乡建设用地增减挂钩项目可视化监管系统为省国土资源部门开展城乡建设用地增减挂钩工作提供了重要的技术支持。它以地理空间数据为基础,提供多种空间的和动态的地理信息并实现信息可视化的系统。可视化监管系统的基本功能是将表格型数据(数据库数据或直接在程序中输入的数据)转换为地理图形显示,然后对显示结果浏览、操作和分析。该文对城乡建设用地增减挂钩项目可视化监管系统的开发环境、总体设计、关键技术及应用进行阐述。

The visualization supervision system can provide an important technical support for provincial de- partment of land and resources in decreasing urban construction using land and increasing rural agricultural using land. Geographical spatial data is the foundation. It can provide a variety of the space and dynamic geographic information and realize the information visualization. The basic function of visualization super- vision system is to turn data type （datas of database and directly inputted datas in the program） into geog- raphy graphs, and then the results can be displayed, operated and analyzed. In this paper, development environment, overall design, and key technology of visualization supervision system have been introduced.
