基于高分辨率遥感影像的GIS制图与建库一体化研究

Study on Integration of GIS Mapping and Database Construction Based on High Resolution Remote-sensing Image

目前,GIS制图与GIS建库已成为地图应用的两大研究方向,但其对数据的要求各不相同:GIS制图应用更注重地图的符号化表达、地图的可视化表达,没有保留地物的完整性,导致数据无法满足后期的空间分析、地图服务发布、数据检索等要求;而GIS建库应用虽然保留了地物的完整性,但不符合长期以来的地图制图规范和读者视觉上的要求。为了满足不同的应用要求,产生了数据重复生产、数据冗余、更新困难等一系列问题。为了解决上述问题,本文以城区图的制作为例,提出了一种基于Arc GIS软件的一体化解决方案,通过获取原始数据、GIS数据库设计、自动建立GIS数据库、矢量化、数据处理、数据检查、自动制图等一系列举措实现了一库两用,避免了生产过程中的重复建设。

At present,GIS mapping and Database construction have become the two research directions of map application,but they have different requirements,GIS mapping application more emphasis on the symbolic expression of the map,the visual representation of the map,without retaining the integrity of the object,The data cannot meet the requirements of the late spatial analysis,map service release,data retrieval and other requirements,and GIS Database construction application although the preservation of the integrity of the features,but does not meet the long-term map mapping specifications and the reader's visual requirements.In order to meet the different application requirements,resulting in data duplication,data redundancy,update and a series of difficulties.Therefore,in order to solve the above problems,this paper presents an integrated solution based on ArcGIS software,which contain GIS database design,automatically builds GIS database,vectorization,data processing,and data check,Automatic mapping and so on.This paper achieve a library dual-use,to avoid duplication of the production process.
