基于GIS技术的影像数据库建立与设计方法研究——以增城市为例

The design and implement method research of image database based on GIS technology:Taking Zengcheng for an example

空间数据库建设是数字城市建设的基础,它对城市规划管理信息系统建设具有重要的支撑作用,文章以广东省增城市为例,基于Geodatabase建立遥感影像和矢量数据空间数据库,以及可视化编程语言和G IS技术实现对影像数据库的一体化管理、分析、查询、显示与更新等操作;以矢量数据与影像数据的统一存储为基础,实现对影像数据库的分析.在G IS技术的支持下,以拓扑关系结构进行空间数据与属性数据的更新,保证了规划修改的实时性与准确性.通过空间数据库技术,不仅提高了现有规划信息的更新速度,实现了多种数据的无缝集成,方便规划部门人员进行数据查询、分析.

Spatial database is the basis of construction of digital cities, it has important role for urban planning and management system. The paper takes Zengcheng City as example to build image database based on Geo-database technology. It establishes image database and uses visual program language to realize the image and vector data management, analysis, query and update etc. It realized the image data and vector data store as the same data structure and realized the analysis function of image database. Based on GIS technology it carried out spatial data and attributed data update according to topology structure and ensured the timing and accuracy of the planning data. Through analysis we find that to build image database to manage spatial data to improve the speed of existing planning information update, it can realize seamless integration of multiple data, and the staff of management and the planning department can query and analyze the spatial data.
